General Motors Corp.General Motors Corp. Schwingbebe!lagerung an einer MembranpumpeVibration vibration mounting on a diaphragm pump

Die Erfindung bezieht sieb auf eine Scbwinghebellagerung an einer Membranpumpe mittels eines Zapfens.The invention relates to a swing lever mounting on a diaphragm pump by means of a pin.

Membranpumpen werden häufig als Brennstoffpumpen für Brennkraftmaschinen verwendet und es besteht dann die Gefahr, dass Leckagen durch die Bohrung des Zapfens eintreten, da der Zapfen im Bereich einer Öffnung liegt, durch die der Schwinghebel in daa Pumpengehäuse eingeführt werdenDiaphragm pumps are often used as fuel pumps for internal combustion engines and there is then the Risk of leaks occurring through the bore of the pin because the pin lies in the area of an opening which the rocker arm is inserted into the pump housing

und Ausbau des Schwinghebels möglich ist. !ferner ist auf die dauernd wechselnde Belastung des Zapfens während des Betriebes Rücksicht zu nehmen.and removal of the rocker arm is possible. ! further is to take into account the constantly changing load on the pin during operation.

Die Erfindung löst die gestellte Aufgabe dadurch, dass die einander entgegengesetzten Enden des Zapfens in an. sich bekannten stirnseitig geschlossenen Nuten gehalten sind , die beiderseits einer Öffnung im Pumpengehäuse für den Durchlass des Schwinghebels liegen, und der Zapfen durch zwei Metallpropfen, die aus weicherem Werkstoff als der Zapfen besteben, wie Aluminium, Messing, Kupfer oder Zink, und in die Nuten überdeckende Ausnehmungen eingetrieben sind , drehfest in den Nuten festgelegt ist.The invention solves the problem in that the opposite ends of the Cone in. known closed at the front Grooves are held, which are located on both sides of an opening in the pump housing for the passage of the rocker arm, and the tenon by two metal plugs made of softer Material as the pin, such as aluminum, brass, copper or zinc, and recesses that cover the grooves are driven, is fixed in a rotationally fixed manner in the grooves.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass die Nuten und die Ausnehmungen in der Anschluss flansch fläch e des Pumpengehäuses vorgesehen sind. Weiterhin ist es vorteilhaft, wenn die Ausnehmungen geneigte Seitenwände haben.In a further embodiment of the invention is provided that the grooves and the recesses are provided in the connection flange surface of the pump housing. It is also advantageous if the recesses have inclined side walls.
