ABSTRACT:
An adjustable hydraulically operated stop for pulsed loading is proposed, which is particularly applicable for the metering piston of a fuel injection system. The stroke of this metering piston can be varied by adjusting a stop body by means of a metering converter. The supply chamber communicating with a fuel source or with the pump work chamber of one of the pump
ozzles of the fuel injection system, whose size is dependent on the stroke of the metering piston, determines the injected fuel quantity. The adjustable hydraulically operated stop encompasses a mechanical stop body, which is movably supported with respect to its adjusting member embodied by a sheath and communicates therewith via fluid, which also surrounds the adjusting member. The adjusting forces for the adjusting member are kept small, and the holding forces required to prevent a change in the position assumed by the adjusting member are kept equal to zero, because pressure fluctuations affecting the fluid are cancelled out with respect to the adjusting member. To this end, the adjusting member is received in its entirety within a fluid-filled chamber. A spring acting upon the stop body assures the constant renewal of the hydraulic cushion in the case of pulsed operation.
