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/nozzles 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.

Abstract: A shutoff apparatus for distributor injection pumps in internal combustion engines is proposed. The apparatus may also be used as a means of overspeed protection, and under the effect of an electromagnetic pushing magnet it opens the high-pressure chamber of the injection pump in order to shut off the engine. The opening of the high-pressure chamber is effected without the use of a valve subjected to the injection pressure, by means of the axial displacement of a pressure-equalized annular cylinder, which causes a relief bore to come into coincidence with the high-pressure chamber. The displacement of the annular cylinder is effected under the pressing action of an electromagnet. The area of the high-pressure chamber located opposite the distributor piston is sealed off by a slidable plug, which is pre-stressed by spring force and is centered via the annular cylinder by the distributor piston. The actuation push rod of the electromagnet acts in the direction along this slidable plug and it may in part replace this element.

Abstract: A fuel injection pump is disclosed for supercharged Diesel internal combustion engines, in particular, a distributor-type injection pump in which the full-load fuel supply quantity is limited by means of a variable stop, controlled in accordance with rpm and air quantity. The injection pump includes a control apparatus whose control member forms a three-dimensional cam, which is rotated by a charge pressure control element and is displaced in the longitudinal direction by a hydraulic adjustment piston actuated in accordance with the rpm level. The three-dimensional surface of the cam includes protuberances whose profile is picked up and transmitted to a full-load stop of an rpm regulator located in an interior chamber of the injection pump, while the adjustment piston, in abutting relationship with the three-dimensional cam, is actuated for axial movement by the pressure of the fuel located in the interior chamber of the pump, and controlled in accordance with rpm.

Abstract: A fuel injection pump for Diesel engines in which a rotating and reciprocating piston pressurizes and distributes fuel to individual pressure lines leading to the injection valves of the engine. In order to change the timing of injection with respect to the engine cycle, there is provided a mechanism to change the relative angle between the pressurizing piston and its drive means, which runs in synchronism with the engine. The mechanism operates hydraulically and is affected by the fuel pressure in the sump of the injection pump. There is also provided a hydraulic control valve mechanism which permits varying amounts of fuel to flow back from the sump to the low pressure side of the fuel delivery pump, thereby changing the injection timing. A primary control valve adjusts the sump pressure on the basis of engine speed while a secondary control valve adjusts the sump pressure on the basis of engine temperature in order to adapt the timing of fuel injection to engine starting and engine warm-up. Various embodiments are presented.
