Description

Brennstoffpumpe. Die vorliegende Erfindung betrifft eine einfache Anordnung der Betätigung und Abstellvorrichtung der Brennstoffpumpe für kompressorlose Dieselmotoren, wobei der Abstellhebel auch gleichzeitig als Handhebel zur Betätigung der Brennstoffpumpe dient, und besteht lediglich in der dargestellten und beschriebenen Konstruktion.Fuel pump. The present invention relates to a simple one Arrangement of the actuation and shutdown device of the fuel pump for compressorless Diesel engines, whereby the shut-off lever also doubles as a hand lever for actuation the fuel pump is used, and consists only in the illustrated and described Construction.

In der Abbildung ist die Anordnung der Brennstoffpumpe samt der Abstellvorrichtung ersichtlich. a ist das Pumpengehäuse, 1r die Brennstoffpumpe, c der Kolben der Pumpe, d der Schwinghebel, der sich um den Bolzen e dreht und vermittels des Nockens f und der Rolle g bin und her bewegt wird. Der Schwinghebes drückt mittels des Anschlages h gegen den Pumpenkolben, der durch die Feder i wieder nach außen gedrückt wird. h stellt den Abstellhebel dar. Derselbe dreht sich um den Bolzen L und drückt durch den Anschlag m gegen den Zapfen tt des Schwinghebels.The illustration shows the arrangement of the fuel pump including the storage device. a is the pump housing, 1r the fuel pump, c the piston of the pump, d the rocker arm, which rotates around the bolt e and is moved and forth by means of the cam f and the roller g bin. The rocker arm presses by means of the stop h against the pump piston, which is pushed outwards again by the spring i. h represents the shut-off lever. The same rotates around the bolt L and presses through the stop m against the pin tt of the rocker arm.

Der Handhebel kann in die Rastenbohrung o und p der Gehäusewand eingesteckt und fixiert werden, indem die Hülse g am Handhebel. gegen eine Feder nach außen gezogen wird, wobei der Zapfen r aus dem Bereich der Bohrung kommt. In der Rast o ist der Schwinghebel seiner freien Betätigung durch den Nocken-überlassen und bewegt dabei den Pumpenkolben hin und her. Wird am Handhebel die Hülse zurückgezogen und der Hebel 'in die Stellung p gebracht, so drückt der Anschlag m geben den Zapfen n des Schwinghebels, und zwar so, daß die Rolle desselben außerhalb des Bereichs des Nockens gelangt und damit die Brennstoffpumpe und die Maschine abgestellt ist.The hand lever can be inserted into the notch hole o and p of the housing wall and fixed by the sleeve g on the hand lever. is pulled outwards against a spring, the pin r coming out of the area of the bore. In the detent o the rocker arm is left to its free actuation by the cam and moves the pump piston back and forth. If the sleeve is withdrawn on the hand lever and the lever 'is brought into position p, the stop m presses the pin n of the rocker arm, in such a way that the roller of the rocker arm gets outside the area of the cam and thus the fuel pump and the machine are switched off is.

Es ist nun oft nötig, die Pumpe von Hand zu betätigen, insbesondere dann, wenn die Öldruckleitung aufgefüllt werden muß oder wenn vor dem Anfahren der Druckleitung noch einige Pumpenhübe Öl zu geben sind. Dies wird hier in einfacher Weise dadurch erreicht, daß die Hülse g am Handgriff nach außen gezogen w=ird und so der Hebel von Hand hin und her geschwenkt werden kann, womit sich auch vermittels des Anschlages tn der Schwinghebel und der Pumpenkolben hin und her bewegt. 'It is now often necessary to operate the pump by hand, especially when the oil pressure line needs to be topped up or when the A few more pump strokes of oil have to be given to the pressure line. This becomes easier here Way achieved in that the sleeve g on the handle w = ird pulled outwards and so the lever can be swiveled back and forth by hand, which also means of the stop tn the rocker arm and the pump piston moves back and forth.

PATENTANSPRUCH: Abstellvorrichtung der Brennstoffpumpe für Dieselmotoren, bei der der Abstellhebel gleichzeitig als Handhebel zur Bedienung der Brennstoffpumpe dient, dadurch gekennzeichnet, daß die äußere einen Rast°nteil (p) tragende Hülse (q) des Handhebels entgegen der Wirkung einer innenliegenden Feder zurückgezogen und beim Auf- und Abschwenken die Brennstoffpumpe angetrieben werden kann, während beim Einstecken in die eine Rast (o) die Pumpe ihrer normalen Tätigkeit durch den Nocken überlassen ist und beim Herausnehmen und Einschwenken in die andere Rast, (p) die Pumpe abgestellt- ist. Claim: Stop device for the fuel pump for diesel engines, in which the stop lever also serves as a hand lever to operate the fuel pump, characterized in that the outer sleeve (q) of the hand lever carrying a locking part (p) is withdrawn against the action of an internal spring and when Swinging up and down the fuel pump can be driven, while when plugging into one detent (o) the pump is left to its normal activity by the cam and when removing and pivoting into the other detent, (p) the pump is switched off.
