摘要： A fuel pressure regulator (22) includes a housing (26) defining a fuel inlet (28) and a fuel outlet (30); a valve seat (32) located between the fuel inlet (28) and the fuel outlet (30), the valve seat (32) being centered about a valve seat axis (44); a valve member (34) centered about a valve member axis (76), the valve member (34) being moveable between 1) a closed position where the valve member (34) engages the valve seat (32) to prevent fuel flow from the fuel inlet (28) to the fuel outlet (30) and 2) an open position where the valve member (34) is disengaged from the valve seat (32) to permit fuel flow from the fuel inlet (28) to the fuel outlet (30); and a grounding member (94) grounded to the housing (26) which engages the valve member (34) to cause the valve member axis (76) to tip relative to the valve seat axis (44) when the valve member (34) moves from the closed position to the open position.

摘要： Die Erfindung betrifft ein Hydrauliksystem (1), mit einer mit einem ersten Hochdruckspeicher (13) verbundenen Pumpeinrichtung (12), die Druckmittel unter Drucksteigerung in den ersten Hochdruckspeicher (13) fördert, mit wenigstens einer Druckverstärkungseinrichtung (17, 18), die mit dem ersten Hochdruckspeicher (13) gekoppelt ist und die das im ersten Hochdruckspeicher (13) befindliche Druckmittel unter weiterer Drucksteigerung in einen zweiten Hochdruckspeicher (22) fördert, wobei wenigstens ein Verbraucher (3) von dem zweiten Hochdruckspeicher (22) mit Druckmittel versorgt wird und wobei zwischen den beiden Hochdruckspeichern (13, 22) wenigstens eine Ventileinrichtung (31, 34) mit der wenigstens einen Druckverstärkungseinrichtung (17, 18) gekoppelt ist, die einen Abfluss von Druckmittel von dem zweiten Hochdruckspeicher (22) in Richtung der wenigstens einen Druckverstärkungseinrichtung (17, 18) verhindert. Erfindungsgemäß ist es vorgesehen, dass der zweite Hochdruckspeicher (22) mit einer Druckreduzierungseinrichtung (25; 25a) gekoppelt ist, mittels der Druckmittel aus dem zweiten Hochdruckspeicher (22) abströmen kann, so dass der Druck im zweiten Hochdruckspeicher (22) reduziert wird.

摘要： A pressure-reduction valve (11) that returns fuel in a common rail (1) to a low-pressure system (9) is configured so that that an actuator (28) changes a valve-opening pressure of the valve device (21) into a target common rail pressure (PC0). Thus, when the actual common rail pressure (PCi) in the common rail (1) exceeds the target common rail pressure (PC0), the pressure-reduction valve (11) opens at once. On the contrary, when the actual common rail pressure (PCi) in the common rail decreases to reach the target common rail pressure (PC0), the pressure-reduction valve (11) closes at once. Accordingly, the pressure-reduction valve (11) limits an overshoot and an undershoot of the actual common rail pressure (PCi) to a minimum without being influenced by a fuel temperature or by detection timings of the common rail pressure sensor (16).

摘要： The invention relates to a fuel injection system for internal combustion engines. Said fuel injection system comprises a high-pressure accumulator chamber (15) that is impinged upon with highly pressurized fuel via a high-pressure conveyor unit (8) and that supplies the fuel injectors (19) with fuel. The high-pressure conveyor unit (8) is associated with a pressure regulating valve (12) that is disposed between a high-pressure side (10, 56) and a low-pressure side (11, 63) and comprises a valve element (54) which is actuated via an electric actuator (47). The pressure regulating valve (12) comprises a housing component (41) with a deformable zone (57) via which a gap L is adjusted between surfaces (48, 49) of an electrically actuated actuator unit (45, 47) when the pressure regulating valve (12) is assembled on a receiving body (52).
