Description

  

  Heiz- und Ventilationseinrichtung an Motorfahrzeugen.    Die Erfindung betrifft eine Einrichtung  an Motorfahrzeugen, insbesondere mit ge  schlossenem Wagenkasten. Sie gestattet, je  nach Temperatur eine Beheizung oder ein  Absaugen der Luft aus dem Wageninnern,  das heisst eine Ventilation vorzunehmen.  



  Aus den Fig. 1 und 2 der Zeichnung ist  ein Ausführungsbeispiel des Erfindungsgegen  standes in der Heizstellung mit Variante er  sichtlich.  



  Das Auspuffrohr A des Motors T führt  in üblicher Weise unter dem Wagenkasten  durch in den bekannten Auspuffkopf P. Um  das erwähnte Auspuffrohr A ist ein Mantel  rohr M von grösserem Durchmesser als jener  des Auspuffrohres angebracht. Dieses in der  Längsrichtung des Fahrzeuges laufende Man  telrohr ist hinten durch eine Klappe D bezw.  K, Fig. 1 bezw. 2 (es könnte auch ein weg  nehmbarer Deckel oder ein Schieber sein),  abgeschlossen und vorn unter dem Wagen  bei E offen. Aus diesem Mantelrohr M führen  Stutzen S und R in den Personenraum J  des Fahrzeuges. Beim Vorwärtsfahren des    Fahrzeuges drückt die Luft auf die Mündung  E des Mantelrohres, wobei durch die Stutzen  S und R ein Strom reiner, heisser Luft in  das Wageninnere strömt.  



  Dieser Heissluftstrom kann in Querröhren  (Fussrasten), welche mit Öffnungen versehen  sind, weitergeleitet werden.  



  Das Mantelrohr M besitzt an seinem  hintern Ende die Klappe K bezw. D, zum  Zwecke, um bei genügend grosser Wagen  innentemperatur bezw. bei genügender Aussen  temperatur die heisse Luft nach hinten aus  treten zu lassen. Hierbei wird bei rascher  Vorwärtsfahrt die Luft aus dem Innenraum  durch die Stutzen R und S bezw. durch S  allein kräftig injektorartig abgesogen, je nach  Einstellung des Deckels D, Fig. 1, oder der  Klappe K, Fig. 2. Es hat sich nämlich ge  zeigt, dass die Absaugung aus dem bezw.  den vordern Stutzen S (wenn mehrere vor  handen sind) genügt, um besonders den vor  deren Personenraum, in den Motordämpfe und  Motorhitze durch die     Pedalöffnungen    leicht  hingelangen, intensiv genug zu lüften.

        Die Einrichtung zum Öffnen des hintern  Endes des Mantelrohres ist auch insofern  von grosser Wichtigkeit, weil sonst bei hoher  Aussentemperatur (Sommer) die eingeschlos  sene Auspuffröhre sehr heiss würde, wodurch  eine rückwirkende, kraftvermindernde Stau  ung der Abgase und Erhitzung des Motors  eintreten könnte; ebenso würden die ins  Wageninnere führenden Stutzen S und R  durch die direkte Ableitung unerwünschte  Hitze verbreiten.



  Heating and ventilation equipment on motor vehicles. The invention relates to a device on motor vehicles, in particular with a closed car body. Depending on the temperature, it allows the air to be heated or extracted from the interior of the car, i.e. ventilation.



  From Figs. 1 and 2 of the drawing, an embodiment of the subject invention is in the heating position with variant it is evident.



  The exhaust pipe A of the engine T leads in the usual way under the car body through in the known exhaust head P. To the aforementioned exhaust pipe A, a jacket pipe M is attached to a larger diameter than that of the exhaust pipe. This running in the longitudinal direction of the vehicle Man telrohr is behind by a flap D BEzw. K, Fig. 1 respectively. 2 (it could also be a removable cover or a slider), locked and open at the front under the carriage at E. From this jacket pipe M, nozzles S and R lead into the passenger compartment J of the vehicle. When the vehicle drives forward, the air presses on the mouth E of the jacket pipe, whereby a stream of pure, hot air flows into the interior of the vehicle through the sockets S and R.



  This stream of hot air can be passed on in cross tubes (footrests) which are provided with openings.



  The jacket tube M has the flap K BEZW at its rear end. D, for the purpose to bezw at a sufficiently large car inside temperature. to let the hot air escape to the rear when the outside temperature is sufficient. In this case, when driving forward rapidly, the air from the interior is respectively through the nozzles R and S. S sucked by S alone powerfully like an injector, depending on the setting of the lid D, Fig. 1, or the flap K, Fig. 2. It has been shown that the suction from the respectively. the front connection S (if several are available) is sufficient to ventilate the area in front of their passenger area where engine fumes and engine heat can easily reach through the pedal openings.

        The device for opening the rear end of the jacket pipe is also of great importance because otherwise the enclosed exhaust pipe would be very hot at high outside temperatures (summer), which could result in a retroactive, force-reducing accumulation of the exhaust gases and heating of the engine; Likewise, the nozzles S and R leading into the interior of the car would spread unwanted heat due to the direct discharge.
