  Dieser starke Widerstand rührt davon her, dass die eingesperrte   Flüssigkeit,     die.   ie im letzten Augenblick durch. das Ventil in ihrer Strömung gedrosselt wird, eine Kataraktwirkung auf Ventil und Kolben   ausübt.   



    Fig. 6 zeigt eine Vereinigung das zwangläung geöffneten Saugventiles mit dew zwangsläufig geschlossenen Druckleitung. In diesem Falle hat der Kolbenschieber l gegen die Druckleitung     vollständig   abgeschlossen und noch um eine gewisse Strecke zum sicheren. Abschluss überschliffen. Ein Druckstoss von der Saugleitung ist wieder unschädlich gemacht. Springt jedoch der Kolben a um eine Strecke zurück, die kleiner als die Überdeckung ist, so wird die Druck- 
 EMI2.2 
 schon eine grössere Strecke geöffnet. Bei dieser Ausführung stellt sich also nicht der Nachteil ein, den die Bauart nach Fig. 2 bringen könnte, dass Stempel b im ersten   Augenblick des Druck-     huhes   einen   erheblichen Widerstand unnütz   zu   übliwinden hätte.   



    PATENT-ANSPRÜCHE:  
1. Brennstoffpumpe für Verbrennungskraftmaschinenmit stossartiger Einleitung des Druckhubes, dadurch gekennzeichnet, dass die   Druck-oder-Saugleitung durch vom Kolben   
 EMI2.3 
 schlossen wird.

 EMI2.1
 



  This strong resistance comes from the fact that the trapped liquid, the. ie at the last moment. the valve is throttled in its flow, has a cataract effect on the valve and piston.



    Fig. 6 shows a combination of the forced open suction valve with the forced closed pressure line. In this case, the piston valve l has completely closed off from the pressure line and still by a certain distance to be safe. Finishing ground. A pressure surge from the suction line is made harmless again. However, if the piston a jumps back by a distance that is less than the overlap, the pressure

 already a longer stretch open. In this embodiment, there is no disadvantage that the design according to FIG. 2 could bring, that stamp b would have to overcome considerable resistance in the first moment of the printing stroke.



    PATENT CLAIMS:
1. Fuel pump for internal combustion engines with sudden initiation of the pressure stroke, characterized in that the pressure or suction line through the piston
 EMI2.3
 is closed.

Claims (1)

2. Pumpe nach Anspruch 1, dadurch gekennzeichnet, dass dem Saugventil ein Windless ?) vorgeschaltet ist (Fig. 1). 2. Pump according to claim 1, characterized in that a windless?) Is connected upstream of the suction valve (Fig. 1). 3. Pumpe nach Anspruch l, dadurch gekennzeichnet, dass der Pumpenkolben gleichzeitig a) s Schieber ausgebildet ist, der am Ende des Saughubes die Druck- oder Saugleitung abschliesst (Fig. 2 und 3). 3. Pump according to claim l, characterized in that the pump piston is formed at the same time a) s slide which closes the pressure or suction line at the end of the suction stroke (Fig. 2 and 3).
