Abstract

The invention relates to a toilet system which can be rinsed by a rinsing device (1). A pipe (29) is connected to the toilet pan and leads to a sanitation pipe (18). Means (8) are provided for transporting a suction material (4) from the toilet pan (5) into the pipe (29) and into the sanitation pipe (18). Said means (8) comprise two valves (7, 16) which are arranged in the pipe (29) and a pressure chamber (12) is disposed in-between. In order to suction the suction material (4) from the toilet pan (5), low pressure is produced in the pressure chamber (12) and used to transport said suctioned material (4). The pressure chamber (12) is embodied as a piston cylinder and the piston (10) is connected to a controllable drive (14) in order to produce the high and low pressure. The inventive toilet system enables rinsing to occur using a very small amount of water and which can be adapted to different toilet pans.

Description

Toilettenanlage mit einer Toilettenschüssel Toilet facility with a toilet bowl

Die Erfindung betrifft eine Toilettenanlage mit einer Toilettenschüssel, die mit einer Spülvorrichtung spülbar ist, mit einer Leitung, die an der Toilettenschüssel angeschlossen ist • und zu einer Entsorgungsleitung führt, mit Mitteln zum Transportieren einer Absaugmasse von der Toilettenschüssel in die Leitung und in die Entsorgungsleitung, welche Mittel in der Leitung zwei Ventile und zwischen diesen eine Druckkammer aufweisen, in der zum Absaugen der Absaugmasse aus der Toilettenschüssel ein Unterdruck und für den Transport der abgesaugten Absaugmasse in die Entsorgungsleitung ein Überdruck erzeugbar ist.The invention relates to a toilet system with a toilet bowl can be flushed with a flushing device, leads to a conduit, which is connected to the toilet bowl • and to a disposal conduit, having means for transporting a suction-extraction substance from the toilet bowl into the conduit and in the discharge line, Which means have two valves in the line and a pressure chamber between them, in which a negative pressure can be generated to extract the suction mass from the toilet bowl and an excess pressure can be generated to transport the extracted suction mass into the disposal line.

Toilettenanlagen, bei denen mittels Vakuum die Absaugmasse abgesaugt wird, sind bisher vor allem in Fahrzeugen, beispielsweise in Bahnwagen und Wohnmobilen bekannt. Beispielsweise offenbart die WO 92/18713 eine Toilettenanlage, bei der eine Vorrichtung zur Erzeugung von Unterdruck, einen Zwischenbehälter und einen Sammelbehälter aufweist . Die genannte Vorrichtung evakuiert zur Erzeugung des Unterdruckes den Zwischenbehälter, sodass bei einem geöffnetem Ventil in einer Leitung die Absaugmasse in den Zwischenbehälter angesaugt wird. Sammelbehälter erfordern viel Platz und müssen geleert werden. Sie sind in der Haustechnik nicht erwünscht .Toilet systems, in which the suction mass is extracted by means of vacuum, have hitherto been known primarily in vehicles, for example in railway carriages and mobile homes. For example, WO 92/18713 discloses a toilet installation in which a device for generating negative pressure has an intermediate container and a collecting container. Said device evacuates the intermediate container in order to generate the negative pressure, so that when an open valve in a line, the suction mass is sucked into the intermediate container. Collection containers require a lot of space and must be emptied. They are not wanted in building technology.

Die EP 0 887 478 offenbart eine Toilettenanlage, bei der eben- falls ein Tank vorgesehen ist. Mittels einer Membranpumpe wird im Tank ein Teilvakuum erzeugt, durch das eine Absaugwirkung erzeugt wird. Die EP 0 806 527 offenbart eine Spülvorrichtung, die ein hohles, becherförmiges Verschlusselement aufweist. Das Verschlusselement arbeitet mit einer Eingangsöffnung und einer Ausgangsöffnung zusammen, die jeweils beide offen oder geschlossen sind.EP 0 887 478 discloses a toilet installation in which a tank is also provided. A partial vacuum is created in the tank by means of a diaphragm pump, which creates a suction effect. EP 0 806 527 discloses a flushing device which has a hollow, cup-shaped closure element. The closure element works together with an inlet opening and an outlet opening, both of which are both open or closed.

Toilettenanlagen mit jeweils einem Sammeltank sind zudem aus der EP 0 704 372 und EP 1 022 399 bekannt geworden.Toilet facilities, each with a collecting tank, are also known from EP 0 704 372 and EP 1 022 399.

Die EP 0 763 633 AI offenbart eine Absaugtoilette, die in der Ablaufleitung zwischen zwei Ventilen eine Druckkammer besitzt. Durch einen Unterdruck in dieser Kammer wird beim Öffnen eines eingangsseitigen Ventils Absaugmasse von der Toilettenschüssel durch die Ablaufleitung in diese Kammer gesaugt . Nach einem Umschalten der beiden Ventile wird mittels Druck die Absaugmasse von der Kammer in eine weitere Leitung gepresst. Zum Evakuieren der Kammer ist eine Saugstrahlpumpe vorgesehen, die mit Druckluft betrieben wird. Ein Faltenbalg in der Druckkammer bildet eine flexible Membran und dient als Dichtungsmittel und soll verhindern, dass schlechte Luft aus der Ablaufleitung nach aussen gelangen kann. Bei der Erzeugung eines Unterdruckes wird eine Feder gespannt, die beim Entspannen einen Druck aufbaut. Bei dieser Toilettenanlage besteht die Schwierigkeit, dass das Abdichten der Kammer mittels einer flexiblen Membran aufwendig und störungsanfällig ist. Der Aufbau eines Unterdruckes erfor- dert mittels einer Saugstrahlpumpe vergleichsweise viel Zeit. Zudem ist der erreichbare Druck zum Ausstossen der Absaugmasse aus der Kammer sehr begrenzt . In der Praxis dürfte sich diese Toilettenanlage kaum bewähren.EP 0 763 633 AI discloses a suction toilet which has a pressure chamber in the discharge line between two valves. Due to a negative pressure in this chamber, when a valve on the inlet side is opened, suction mass is sucked from the toilet bowl through the drain line into this chamber. After switching over the two valves, the suction mass is pressed from the chamber into another line by means of pressure. A suction jet pump, which is operated with compressed air, is provided for evacuating the chamber. A bellows in the pressure chamber forms a flexible membrane and serves as a sealant and is intended to prevent bad air from escaping from the drain line. When a vacuum is generated, a spring is tensioned, which builds up pressure when the pressure is released. The problem with this toilet system is that sealing the chamber by means of a flexible membrane is complex and prone to failure. It takes a comparatively long time to build up a vacuum using a suction jet pump. In addition, the achievable pressure for expelling the suction mass from the chamber is very limited. In practice, this toilet facility is unlikely to prove itself.

Der Erfindung liegt die Aufgabe zugrunde, eine Toilettenanlage der genannten Art zu schaffen, die bei geringem Wasserverbrauch funktionssicher und dauerhaft ist. Die Aufgabe ist bei einer gattungsgemässen Toilettenanlage dadurch gelöst, dass die Druckkammer als Kolbenzylinder ausgebildet ist und der Kolben zur Erzeugung des Über- bzw. Unterdrucks mit einem steuerbaren Antrieb verbunden ist. Bei der erfindungs- gemässen Toilettenanlage wird der Unter- bzw. Überdruck durch Bewegen des Kolbens erzeugt. Dies ermöglicht einen sehr schnellen Aufbau eines Unterdruckes, beispielsweise innerhalb eines Bruchteils einer Sekunde. Ein Überdruck kann ebenfalls sehr schnell und zudem mit einem Überdruck über lbar, beispielsweise etwa 2bar erzeugt werden. Ein weiterer Vorteil der erfindungsge- mässen Toilettenanlage wird darin gesehen, dass der Hub und damit das absaugbare Volumen der Absaugmasse genau einstellbar ist. Es ist auch möglich, nacheinander zwei oder mehr Absaugzyklen durchzuführen. Damit ist mit sehr wenig Wasser ein sauberer Spülvorgang möglich. Der Kolben des Kolbenzylinders kann hier selbst als Dichtungsmittel dienen, das ein Entweichen schlechter Luft nach aussen verhindert. Eine flexible Membran oder dergleichen ist somit nicht erforderlich. Die Bewegung des Kolbens erfolgt gemäss einer Weiterbildung der Erfindung mittels eines Elektromotors. Dies ermöglicht in Verbindung mit einer Steuervorrichtung eine exakte und genaue Steuerung des Absaug- bzw. Ausstossvorganges . Diese Vorgänge sind zudem einstellbar und an die jeweilige Toilettenschüssel anpassbar.The invention has for its object to provide a toilet system of the type mentioned, which is reliable and durable with low water consumption. The object is achieved in a generic toilet system in that the pressure chamber is designed as a piston cylinder and the piston is connected to a controllable drive for generating the overpressure or underpressure. In the toilet system according to the invention, the negative or positive pressure is generated by moving the piston. This enables a vacuum to be built up very quickly, for example within a fraction of a second. An overpressure can also be generated very quickly and also with an overpressure above 1 bar, for example about 2 bar. Another advantage of the toilet system according to the invention is seen in the fact that the stroke and thus the volume of the suction mass that can be extracted is precisely adjustable. It is also possible to carry out two or more suction cycles in succession. This enables a clean rinsing process with very little water. The piston of the piston cylinder can itself serve as a sealant that prevents bad air from escaping to the outside. A flexible membrane or the like is therefore not necessary. According to a development of the invention, the piston is moved by means of an electric motor. In conjunction with a control device, this enables precise and precise control of the suction or ejection process. These processes are also adjustable and adaptable to the respective toilet bowl.

Ein Ausfuhrungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnungen näher erläutert. Es zeigen:An exemplary embodiment of the invention is explained in more detail below with reference to the drawings. Show it:

Fig. 1 schematisch eine erfindungsgemässe Toilettenanlage, Fig. 2 eine weitere schematische Darstellung der erfindungsge- mässen Toilettenanlage, Fig. 3 schematisch der zeitliche Verfahrensablauf eines Spül- vorgangs und Fig. 4-6 schematisch das Ansaugen und Ausstossen von Absaugmasse.1 schematically shows a toilet installation according to the invention, FIG. 2 shows a further schematic illustration of the toilet installation according to the invention, FIG. 3 schematically shows the time sequence of a flushing process and Fig. 4-6 schematically the suction and ejection of suction mass.

Die Toilettenanlage weist gemäss den Fig. 1 und 2 eine Toilet- tenschussel 5 auf, die trichterförmig ausgebildet und einen unteren Ausgang 5a aufweist. Dieser Ausgang 5a ist jedoch vergleichsweise klein und weist einen Querschnitt von beispielsweise 30 mm2 auf. An der Unterseite dieses Ausganges 5a ist in einer Leitung 29 eine Saugleitung 6 angeschlossen, die ebenfalls einen vergleichsweise kleinen Querschnitt aufweist. Die Toilettenschüssel 5 ist mit einer Spülvorrichtung 1 spülbar und weist ein Spülrohr 3 auf, durch das Spülwasser in das Innere der Toilettenschüssel 5 einleitbar ist. Die Spülvorrichtung 1 kann ein Spülkasten oder eine andere geeignete Spülvorrichtung sein. We- sentlich ist jedoch, dass vergleichsweise wenig Spülwasser verwendet wird, beispielsweise weniger als ein Liter. Die Auslösung der Spülung erfolgt an einer Taste 2 oder an einer anderen geeigneten Auslösevorrichtung. Denkbar ist hier auch eine berührungslose oder automatische Auslösung.1 and 2, the toilet system has a toilet bowl 5 which is funnel-shaped and has a lower outlet 5a. However, this output 5a is comparatively small and has a cross section of, for example, 30 mm 2 . At the bottom of this outlet 5a, a suction line 6 is connected in a line 29, which also has a comparatively small cross section. The toilet bowl 5 can be flushed with a flushing device 1 and has a flushing tube 3 through which flushing water can be introduced into the interior of the toilet bowl 5. The flushing device 1 can be a cistern or another suitable flushing device. It is essential, however, that comparatively little rinse water is used, for example less than one liter. The flush is triggered using a button 2 or another suitable triggering device. Contactless or automatic triggering is also conceivable here.

In der Saugleitung 6 ist ein Ventil 7 angeordnet, das in einem geschlossenen Zustand die Saugleitung 6 absperrt und in geöffnetem Zustand den Durchgang zu einer Kammer 12 eines Kolbenzylinders 8 freigibt . Das Ventil 7 wird über eine Signalleitung 24 von einer Steuervorrichtung 26 gesteuert.A valve 7 is arranged in the suction line 6, which shuts off the suction line 6 in a closed state and opens the passage to a chamber 12 of a piston cylinder 8 in the open state. The valve 7 is controlled by a control device 26 via a signal line 24.

Der Kolbenzylinder 8 weist ein Gehäuse 9 auf, in dem ein Kolben 10 in den Richtungen des Doppelpfeiles 19 begrenzt verschiebbar ist. Der Kolben 10 unterteilt das Gehäuse 9 in eine untere Kammer 12 und in eine obere Kammer 13. Der Kolben 10 dichtet diese beiden Kammern 12 und 13 gegeneinander ab. Dazu ist an der Aussenseite des Kolbens 10 eine umlaufende Dichtung 10a angeordnet. Der Kolben 10 wird mit einem Motor 14, bei- spielsweise einem Elektromotor bewegt und ist mit dem Kolben 10 über eine Kolbenstange 11 verbunden, die wie ersichtlich mit dem einen Ende aus dem Gehäuse 9 herausragt. Bei der Bewegung des Kolbens 10 wird aus der Oberkammer 13 mittels Ventilen 22 und 23 Luft in die Umgebung ausgestossen, bzw. Frischluft aus der Umgebungsluft angezogen. Die Ventile 22 und 23 können einfache Klappenventile sein. Die Stromversorgung des Motors 14 erfolgt über eine Stromleitung 15. Über diese Leitung wird ebenfalls die Steuervorrichtung 26 versorgt. Die Steuervorrichtung 26 kann auch im Motor 14 integriert sein.The piston cylinder 8 has a housing 9 in which a piston 10 can be displaced to a limited extent in the directions of the double arrow 19. The piston 10 divides the housing 9 into a lower chamber 12 and an upper chamber 13. The piston 10 seals these two chambers 12 and 13 against one another. For this purpose, a circumferential seal 10a is arranged on the outside of the piston 10. The piston 10 is driven by a motor 14, for example, an electric motor and is connected to the piston 10 via a piston rod 11 which, as can be seen, protrudes from the housing 9 at one end. When the piston 10 moves, air is expelled from the upper chamber 13 into the environment by means of valves 22 and 23, or fresh air is drawn in from the ambient air. The valves 22 and 23 can be simple flap valves. The motor 14 is supplied with power via a power line 15. The control device 26 is likewise supplied via this line. The control device 26 can also be integrated in the motor 14.

Die untere Kammer 12 weist einen Ausgang 12a auf, der wie ersichtlich an der untersten Stelle der unteren Kammer 12 angeordnet ist und an dem eine Druckleitung 17 angeschlossen ist. Die Druckleitung 17 kann ein flexibler Schlauch oder eine feste Rohrleitung sein. In der Nähe des Ausganges 12a befindet sich ein weiteres Ventil 16, das über eine Signalleitung 25 von der Steuervorrichtung 26 gesteuert ist. In einem Zustand ist der Durchgang zur Druckleitung 17 verschlossen und im anderen Zu- stand frei. Die untere Kammer 12 bildet eine Druckkammer und diese kann in die Toilettenschüssel 5 integriert sein und mit dieser eine Einheit bilden.The lower chamber 12 has an outlet 12a which, as can be seen, is arranged at the lowest point of the lower chamber 12 and to which a pressure line 17 is connected. The pressure line 17 can be a flexible hose or a fixed pipe. Another valve 16 is located in the vicinity of the outlet 12a and is controlled by the control device 26 via a signal line 25. In one state the passage to the pressure line 17 is closed and in the other state it is free. The lower chamber 12 forms a pressure chamber and this can be integrated in the toilet bowl 5 and form a unit with this.

Die Druckleitung 17 weist einen Querschnitt auf, der in wesent- liehen dem Querschnitt der Saugleitung 6 entsprechen kann. Dieser Querschnitt ist somit ebenfalls vergleichsweise klein und kann etwa mit demjenigen eines Gartenschlauches verglichen werden. Er kann vergleichsweise lang, beispielsweise mehrere Meter lang sein und führt gemäss Fig. 1 zu einem Fallrohr einer Ent- sorgungsleitung 18. Vorzugsweise weist die Druckleitung 17 ein vorderes Ende 17a auf, das vergleichsweise tief, beispielsweise mehrere Meter in eine Entsorgungsleitung 18 hineinragt. Die Druckleitung 17 ist beispielsweise durch einen seitlichen Stut- zen 18a in die Entsorgungsleitung 18 eingeführt.The pressure line 17 has a cross section which can essentially correspond to the cross section of the suction line 6. This cross-section is therefore also comparatively small and can be compared to that of a garden hose, for example. It can be comparatively long, for example several meters long, and, according to FIG. 1, leads to a downpipe of a disposal line 18. The pressure line 17 preferably has a front end 17a which projects comparatively deep, for example several meters, into a disposal line 18. The pressure line 17 is, for example, by a lateral fillet zen 18a introduced into the disposal line 18.

Nachfolgend wird die Arbeitsweise der erfindungsgemässen Toilettenanlage erläutert .The mode of operation of the toilet installation according to the invention is explained below.

Der Ruhezustand der Toilettenanlage ist in Fig. 2 gezeigt. Die Ventile 7 und 16 sind geschlossen und der Kolben 10 befindet sich in der gezeigten unteren Stellung. Bei der Benutzung der Toilettenanlage kann die Spülvorrichtung 1 für eine Vorbenetzung der Innenseite 5b der Toilettenschüssel 5 betätigt werden. Durch die Benützung sammelt sich in der Toilettenschüssel 5 die Absaugmasse 4, welche die Saugleitung 6 bis zum Ventil 7 füllt. Durch Betätigen der Auslösetaste 2 wird eine Spülung ausgelöst. Wasser gelangt hierbei durch das Spülrohr 3 in die Toiletten- schüssel 5. Die hier verwendete Wassermenge wird über die Steuerung 26, und die Signalleitung 27 gesteuert. Vorzugsweise ist eine oder mehrere Düsen vorgesehen, welche hierbei die Innenseite 5b der Toilettenschüssel 5 besprüht.The idle state of the toilet system is shown in Fig. 2. The valves 7 and 16 are closed and the piston 10 is in the lower position shown. When using the toilet system, the flushing device 1 can be actuated for prewetting the inside 5b of the toilet bowl 5. Through use, the suction mass 4 collects in the toilet bowl 5 and fills the suction line 6 up to the valve 7. A flush is triggered by pressing the trigger button 2. In this case, water reaches the toilet bowl 5 through the flushing pipe 3. The amount of water used here is controlled by the controller 26 and the signal line 27. One or more nozzles are preferably provided, which in this case spray the inside 5b of the toilet bowl 5.

Nach dem Besprühen fährt der Kolben 10 etwa in die in Fig. 4 gezeigte Stellung. Vorzugsweise wird hier die oberste Stellung nicht ganz erreicht. Da die Ventile 7 und 16 noch geschlossen sind, wird dadurch in einer Kammer 12' ein Unterdr ck erzeugt, der vorzugsweise kleiner als etwa 0,5bar ist. Gleichzeitig kann über die Steuervorrichtung 26 eine weitere Spülung der Toilettenschüssel 5 ausgelöst werden. Etwa gleichzeitig wird das Ventil 7 vergleichsweise schnell und somit im wesentlichen plötzlich geöffnet. Das schnelle Öffnen kann beispielsweise durch eine hier nicht gezeigte vorgespannte Feder erfolgen. Etwa gleich- zeitig wird die Spülung der Toilettenschüssel 5 unterbrochen. Die untere Kammer 12' ist so gross, dass diese etwa zur Hälfte mit Luft und zur Hälfte mit Absaugmasse 4 gefüllt ist. Beim Ansaugen der Absaugmasse 4 werden die Feststoffe durch das plötz- liehe Einströmen in die unter Kammer 12' verkleinert, sodass die abgesaugte Absaugmasse 4' ähnlich einer Suspension vorliegt. Die Fig. 5 zeigt mit dem Pfeil 28 die Einströmrichtung der Absaugmasse 4 in die Unterkammer 12 ' . Über der Absaugmasse 4 ' befindet sich ein Luftpolster 21, das wie oben erwähnt, etwa das halbe Volumen der unteren Kammer 12 ' einnimmt .After spraying, the piston 10 moves approximately into the position shown in FIG. 4. The uppermost position is preferably not fully reached here. Since the valves 7 and 16 are still closed, a vacuum is generated in a chamber 12 ', which is preferably less than about 0.5 bar. At the same time, a further flushing of the toilet bowl 5 can be triggered via the control device 26. At about the same time, the valve 7 is opened comparatively quickly and thus essentially suddenly. The rapid opening can take place, for example, by means of a prestressed spring, not shown here. At about the same time, the flushing of the toilet bowl 5 is interrupted. The lower chamber 12 'is so large that it is filled approximately half with air and half with suction mass 4. When the suction mass 4 is sucked in, the solids are inflow into the chamber 12 'is reduced, so that the extracted mass 4' is similar to a suspension. 5 shows with arrow 28 the inflow direction of the suction mass 4 into the lower chamber 12 '. Above the suction mass 4 'there is an air cushion 21 which, as mentioned above, takes up about half the volume of the lower chamber 12'.

Ist die Absaugmasse 4 abgesaugt, so wird das Ventil 7 geschlossen und der Kolben 10 fährt nach unten, wobei das Luftpolster 21 komprimiert und ein Überdruck von beispielsweise 2bar erzeugt wird. Nun wird das Ventil 16 geöffnet und infolge des Überdruk- kes wird die Absaugmasse 41 in die Druckleitung 17 und schliess- lich in die Entsorgungsleitung 18 ausgestossen. Anschliessend wird das Ventil 16 geschlossen. Bei der Bewegung des Kolbens 10 nach unten wird von der Umgebungsluft Frischluft über das Ventil 22 in die obere Kammer 13 eingeleitet. In der Regel ist die Druckleitung 17 wenigstens teilweise mit Absaugmasse 4' gefüllt. Um auch diese Absaugmasse auszustossen, wird vorzugsweise ein zweiter Spülvorgang ausgelöst. Hierbei wird die Toilettenschüs- sei 5 nochmals gespült und dieses Spülwasser wird mit dem oben erläuterten Vorgang angesaugt und anschliessend ausgestossen. Die Druckleitung 17 wird durch diesen weiteren Vorgang mit Wasser durchgespült und wenigstens teilweise gereinigt. Dieses weitere Spülwasser gelangt in die Entsorgungsleitung 18.If the suction mass 4 is sucked off, the valve 7 is closed and the piston 10 moves downward, the air cushion 21 being compressed and an overpressure of, for example, 2 bar being generated. Now the valve 16 is opened and, as a result of the overpressure, the suction mass 4 1 is expelled into the pressure line 17 and finally into the disposal line 18. The valve 16 is then closed. When the piston 10 moves downward, fresh air is introduced into the upper chamber 13 via the valve 22 from the ambient air. As a rule, the pressure line 17 is at least partially filled with suction mass 4 '. In order to also eject this suction mass, a second rinsing process is preferably triggered. Here, the toilet bowl 5 is rinsed again and this rinsing water is sucked in with the above-described process and then expelled. The pressure line 17 is flushed through with this further process and at least partially cleaned. This further rinse water reaches the disposal line 18.

Die Saugleitung 6 mündet vorzugsweise tangential und vorzugsweise auch nach unten in die Druckkammer 12. Dies ergibt eine besonders günstige Dynamik der Absaugmasse 4 und damit das Ein- und Ausströmen dieser Masse 4 im Zylinder 8. Die Absaugmasse 4 strömt tangential und nach unten gerichtet in die Druckkammer 12 und spült damit sozusagen den Zylinder 8 und rotiert in der Druckkammer 12. Anschliessend wird die Absaugmasse 4 ausgestossen. Da alles in Bewegung ist, kann ein Absetzen in der Druckkammer 12 vermieden werden. Eventuell doch abgesetzte Teile werden wieder aufgespült . Ein Kontakt mit dem Kolben 10 und der Dichtung wird weitgehend vermieden. The suction line 6 preferably opens tangentially and preferably also downwards into the pressure chamber 12. This results in a particularly favorable dynamic of the suction mass 4 and thus the inflow and outflow of this mass 4 in the cylinder 8. The suction mass 4 flows tangentially and downwards into the Pressure chamber 12 and thus rinses cylinder 8, so to speak, and rotates in pressure chamber 12. Subsequently, suction mass 4 is expelled. Since everything is in motion, a stop in the Pressure chamber 12 can be avoided. Any parts that have settled are washed up again. Contact with the piston 10 and the seal is largely avoided.
