geführten Querschnitt die Gestalt eines gleichschenkeligen Dreieckes, dessen Seiten pinaliel zu den schrägen Seiten der Zähne der Zahnung laufen und etwas'kürzer sind als diese. Der achsiale Zwischenraum zwischen der Zahnung beider Scheiben 6,7 ist derart bemessen, dass der relative achsiale Vorschub, der erforderlich ist, damit die Prismen 24, 25 aus jener Lage, in der
EMI2.2
(Fig. 9) eingreifen, dem Ventilhube gleicht.
Die Arbeitsweise der ganzen Einrichtung ist folgende : Beim Anheben des Ventiltellers werden auch die fest mit der Ventilspindel verbundenem Teile 6,7 und 8 angehoben, so dass die Prismen 24, 25, die bei geschlossenem Ventile mit der oberen Zahnung 6 (Fig. 7) in Eingriff standen und beim Hub des Ventiles in Ruhe bleiben, noch vor Beendigung des Hubes gegen die um die halbe Teilung versetzte untere Zahnung der Scheibe 7 stossen, die beim Hube des

keine Beschädigung eintrete, kann sich der Hebel 28 mit den Prismen 24, 25 ein wenig anheben, und zwar entgegen dem Drucke der Feder 32, deren Spannung entsprechend geregelt werden kann. Beim Senken des Ventiles stossen die Prismen wiederum gegen die Zähne der oberen Scheibe 6 (Fig.
10) und bewirken eine zweite Verdrehung des Ventiltellers in der übereinstimmenden

EMI2.1
The guided cross-section has the shape of an isosceles triangle, the sides of which run pinaliel to the inclined sides of the teeth of the toothing and are slightly shorter than these. The axial gap between the teeth of the two disks 6, 7 is dimensioned such that the relative axial advance that is required so that the prisms 24, 25 from that position in which
EMI2.2
(Fig. 9) intervene, resembles the valve lift.
The operation of the entire device is as follows: When the valve plate is raised, the parts 6, 7 and 8 that are firmly connected to the valve spindle are also raised, so that the prisms 24, 25, which, when the valves are closed, have the upper teeth 6 (Fig. 7) were in engagement and remain at rest during the stroke of the valve, before the end of the stroke against the lower toothing of the disc 7 offset by half the pitch, which during the stroke of the

If no damage occurs, the lever 28 with the prisms 24, 25 can raise a little, against the pressure of the spring 32, the tension of which can be regulated accordingly. When the valve is lowered, the prisms again hit the teeth of the upper disc 6 (Fig.
10) and cause a second rotation of the valve disk in the corresponding
