摘要： A lift-controlled valve as a fuel metering device of an injection system for internal combustion engines has a valve needle which may be actuated axially against the resistance of a spring, the valve needle being situated in a graduated coaxial recess in a valve body and interacting with a valve seat formed in the recess of the valve body in this case controlling the fuel injection process; the valve has in addition a high-pressure area which is connected to an assigned injection nozzle and which is located upstream from the valve seat, a low-pressure area which is located downstream from the valve seat and which opens out into a fuel return flow, and a low-pressure equalizing piston which coaxially adjoins the valve and which is fixedly connected to the valve needle. The characterizing feature is that a first control edge is formed on the low-pressure equalizing piston, the control edge interacting with a second control edge on the valve body recess in the area of the fuel return flow or in such a way that a throttle cross-section which is dependent on the valve lift is formed between the two control edges.

摘要： The invention relates to a stroke-controlled valve which is used as a fuel metering device of an injection system for internal combustion engines. Said valve has a valve needle (11) which can be actuated axially against the resistance of a spring (24), which is arranged in a graduated, coaxial recess (13) in a valve body (10) and which interacts with a valve seat (17) which is configured in the recess (13) of the valve body (10), hereby controlling the fuel injection process. The valve also comprises a high-pressure area (18) which is connected to an allocated injection nozzle and which is located in front of the valve seat (17), a low-pressure area (28) which is located behind the valve seat and which opens out into the fuel return passage (30); and a low-pressure compensating piston (22) which coaxially adjoins the valve (16, 17) and which is solidly connected to the valve needle. The invention is characterised in that a first control edge (39 or 42) is configured on the low-pressure compensating piston (22). Said control edge interacts with a second control edge (40 or 43) on the valve body recess (13) in the area of the fuel return passage (45, 30) or (48, 30) in such a way that a throttle cross-section (38, 38a or 46, 44a) that is dependent on the valve stroke (41) is formed between the two control edges (39, 40 or 42, 43).

摘要： An electromagnetic valve-controlled fuel injection pump for internal combustion engines, especially diesel engines, comprises an electromagnetic valve (18) whose valve needle (17), via a valve seat (16) located inside the pump body, disconnects a high-pressure area (14, 15) from a low-pressure area (21) or connects the high-pressure and low-pressure areas, whereby the duration of injection is controlled by the opening of the electromagnetic valve (18). In addition, a low-pressure compensating plunger (24), which is arranged inside the low-pressure area (21), is provided for compensating for variations in pressure inside this low-pressure area (21). The invention is characterized in that the low-pressure compensating plunger (24), which is arranged coaxial to the electromagnetic valve needle (17), is provided as a component that is separate from the electromagnetic valve needle (17). This ensures an unimpeded and thus fastest possible opening of the electromagnetic valve (18) by the opening force that the electromagnet exerts upon the electromagnetic valve needle (17).

摘要： The invention relates to a magnetic coil which is arranged in a cup-shaped housing (6) with a connecting piece (9) to guide magnetic flow to a magneto inductor. The position of the magnetic coil inside the cup-shaped housing is fixed by an extrusion coating of insulating material (11). The magnetic coil has extrusion-coated insulated contact terminals (5) protruding outwards from the bottom (8) of the cup-shaped housing. The base (8) of the cup-shaped housing has a third opening which is also filled with insulating material and which enables a pin-like element (25) to be inserted during the extrusion coating process in order to support the magnetic coil.

摘要： A fuel injection pump for internal combustion engines which has a moving part supported in a housing bore and on its jacket face on one side, has an exit opening that is under high pressure, and whose bearing is improved by virtue of the fact that on the jacket face of the part or in the wall of the housing bore, at least one pressure compensation is provided. The compensation face is connected to a high pressure source, is disposed on a side of the jacket face of the part which side is remote from the exit opening, and is continuously covered by the wall of the housing bore. As a result, a compensation of the pressure action by means of the pressure field prevailing in the region of the exit opening occurs so that an improved, less damage-prone bearing is produced with a greater high pressure tightness of the moving part.
