    摘要： The invention relates to a hydrostatic axial piston machine, which has a compact construction with a high power-to weight ratio of several kW/kG, high overall efficiency higher than 90 % and considerably reduced working noise. Its working pressure exceeds 42 MPa and machine working as a pump is self-sucking. The machine in accordance with the invention is characterised in that the shaft (2) is equipped with an axial cam (6), which drives the elements controlling the working medium's flow between working chambers and the low- or high-pressure channels (12, 13) and with immovably attached on the shaft (2) support plate (3) with a fixed inclination angle, while the flow controlling element's shape is preferably a sleeve (9) with at least one hole (10) and a projection (11) supported on the cam's (6) running surface, and the internal surface of the sleeve (9) with at least one piston (5) head form together the working chamber.

    摘要： Eine Verstellvorrichtung (10) umfasst hydraulisch betätigbare Stellmittel (11,..,20), welche durch Beaufschlagung von gegeneinander wirkenden Druckflächen mit einem Stelldruck von einer Neutralstellung aus wahlweise in entgegengesetzte Richtungen auslenkbar sind, sowie weiterhin Steuermittel (27,..,35), durch welche nach Massgabe eines Steuersignals die beiden Druckflächen wahlweise mit einem Stelldruck beaufschlagbar ist, welche Steuermittel (27,..,35) ein verschiebbares Steuerelement (27) umfassen, welches nach Massgabe des Steuersignals aus einer Neutralstellung heraus in entgegengesetzte Richtungen auslenkbar ist, und in einer ausgelenkten Position je nach Richtung der Auslenkung die eine oder die andere Druckfläche mit einem mit der Grösse der Auslenkung zunehmenden Stelldruck beaufschlagt, wobei zwischen den Stellmitteln (11,..,20) und dem Steuerelement (27) mechanische Rückführungsmittel (21,..,26) angeordnet sind, welche eine mit der Auslenkung der Stellmittel (11,..,20) zunehmende Rückstellkraft auf das verschiebbare Steuerelement (27) ausüben.
    Bei einer solchen Verstellvorrichtung werden ein vereinfachter, kompakter Aufbau und gleichzeitig grössere Verstellwege dadurch ermöglicht, dass die mechanischen Rückführungsmittel (21,..,26) über gegenläufig wirkende, die Rückstellkraft erzeugende Zugfedern (21, 22) derart an die Stellmittel (11,..,20) angekoppelt sind, dass sich die Wirkung der Zugfedern (21, 22) in der Neutralstellung der Stellmittel (11,..,20) und des Steuerelements (27) aufhebt.

    摘要： The present invention relates to an improved fluid actuated system (10), such as those used in hydraulically actuated fuel injectors of an internal combustion engine (12). A fluid pump (18) supplies hydraulic fluid to a high pressure rail (14) that in turn supplies the fuel injectors (16) with high pressure fluid. Pump output control is provided by an actuator (51) and an electronic control module (52). A position sensor (58) provides data related to actuator position to the electronic control module (52). Pump control parameters are determined by the electronic control module (52), based on fluid pressure, engine operating conditions and actuator position.

    摘要： A high pressure pump system (14) for use with a hydraulic engine system (10), such as a fuel injection system (10) or a compression release brake system, provides variable delivery of pressurized fluid using sleeve metering principles. The relative position of metering sleeves (56) with respect to pumping pistons (32) is controlled electro-hydraulically by a control circuit (60, 160). The control circuit (60, 160) receives pressurized fluid from the pump delivery gallery (50) or another high pressure area (50, 52) and, using a pressure reducer (64, 164), reduces the operating pressure within the control circuit (60, 160) to a substantially constant pressure lower than the pump output pressure. Lower operating pressure within the control circuit (60, 160) improves the manufacturability of the control circuit components and helps to achieve better control of the pump output.
