Description

Es ist bei Explosionskraftmaschinen von außerordentlicher Bedeutung, ein gleichmäßiges Einströmen des flüssigen Brennstoffes in den Pumpenzylinder zu bewirken, so daß dieser gleichzeitig mit der Saugbewegung des Kolbens gefüllt wird. Die bekannten, aus einem mit Luft gefüllten, unten offenen Gehäuse bestehenden Saugwindkessel sind infolge der Gefahr, daß Luft in die Pumpe mitgerissen wird, für die Brennstoffpumpen von Explosionskraftmaschinen nicht verwendbar.It is extremely important in explosion engines, a uniform To cause the liquid fuel to flow into the pump cylinder, so that this is filled simultaneously with the suction movement of the piston. The known, from one Air-filled, open-bottom housing existing suction air vessels are due to the Risk of air being entrained into the pump for the fuel pumps of explosion engines not useable.

Den Gegenstand vorliegender Erfindung bildet nun eine Einrichtung, gemäß welcher an Stelle des gewöhnlichen Saugwindkessels ein in die Saugleitung vor dem Saugventil eingesetzter Druckbehälter mit einer auf der Außenseite vom Druck der Atmosphäre belasteten Membran verwendet wird.The subject of the present invention now forms a device according to which Instead of the usual suction air vessel, one in the suction line in front of the suction valve used pressure vessel with one loaded on the outside by the pressure of the atmosphere Membrane is used.

In der beiliegenden Zeichnung ist eine beispielsweise Ausführungsform der Erfindung dargestellt.In the accompanying drawing is an example Embodiment of the invention shown.

In dem Pumpenzylinder b, welcher durch das Saugventil c gegen die Saugleitung d und durch das Druckventil e gegen die Druck leitung f abgesperrt ist, bewegt sich der Pumpenkolben α. Unmittelbar hinter dem Saugventil c ist in die Saugleitung der Behälter g eingeschaltet, dessen eine Wand von einer dem äußeren Atmosphärendruck und dem inneren Flüssigkeitsdruck ausgesetzten Membran h gebildet wird. . Bei der Saugbewegung des Pumpenkolbens α wird zunächst in gewöhnlicher Weise das Saugventil c geöffnet , zugleich wird aber auch die Membran h nach innen gedrückt, was zur Folge hat, daß die Flüssigkeit von dem Behälter.g, unabhängig von der Trägheit der Flüssigkeit in der Leitung, sofort durch das geöffnete Saugventil eingepreßt wird und dem Pumpenkolben unmittelbar folgt, so daß hinter dem Kolben kein Vakuum entstehen kann. Der Pumpenzylinder wird demnach vollständig gefüllt, und wenn der Kolben umkehrt und das Saugventil geschlossen wird, so wird die bestimmte Menge Flüssigkeit durch das Druckventil β hinäusgedrückt. Während des Druckhubs hat die Flüssigkeit Zeit, von der Saugleitung d in den Behälter nachzuströmen und diesen von neuem vollständig zu füllen, wobei die Membran h wieder nach auswärts gedrückt wird. Der Behälter g kann selbstverständlich auch mit mehreren Membranen h versehen sein.In the pump cylinder b, which is blocked by the suction valve c against the suction line d and by the pressure valve e against the pressure line f , the pump piston moves α. Immediately behind the suction valve c, the container g is connected in the suction line, one wall of which is formed by a membrane h exposed to the external atmospheric pressure and the internal liquid pressure. . During the suction movement of the pump piston α , the suction valve c is first opened in the usual manner, but at the same time the membrane h is also pressed inwards, with the result that the liquid is removed from the container. g, regardless of the inertia of the liquid in the line, is immediately pressed in through the open suction valve and immediately follows the pump piston, so that no vacuum can develop behind the piston. The pump cylinder is therefore completely filled, and when the piston reverses and the suction valve is closed, the specific amount of liquid is pushed out through the pressure valve β. During the pressure stroke, the liquid has time to flow from the suction line d into the container and completely fill it again, the membrane h being pushed outwards again. The container g can of course also be provided with several membranes h .
