摘要： The hydraulic machine comprises a cam (4) and a cylinder block with pistons (14) collaborating with the lobes of the cam, which lobes each have two ramps (50A, 50B) extending between top dead centre and bottom dead centre (PH, PB) arcs. The cylinders are connected alternately to a supply and to an exhaust, according to sequences separated by switchover phases comprising a phase of isolation with respect to the main, supply and exhaust, ducts. The angular position of the start or end of at least one first phase of isolation with respect to the corresponding dead centre arc differs from the angular position of the start or end of at least a second phase of isolation with respect to its corresponding dead centre arc, these dead centre arcs both being top dead centre or bottom dead centre arcs.

摘要： The invention relates to a high-pressure fuel pump (10) used for a fuel system of a direct injection internal combustion engine. Said fuel pump comprises a housing (12), a low-pressure inlet (18), and a high-pressure outlet (20) which can be connected to a fuel collector line (22). In order to provide a high-pressure fuel pump (10) which is as compact as possible, the fuel collector line (22) is integrated into the housing (12) of said high-pressure fuel pump (10).

摘要： Es wird eine verstellbare Radialkolbenmaschine (Pumpe oder Motor) vorgeschlagen, deren Triebwerk (10) bei einer relativ schmalen Bauweise einen besonders guten mechanischen Wirkungsgrad aufweist.
Das Triebwerk (10) hat einen Hubring (19), der konzentrisch zu einem Rotor (11) angeordnet ist und der zur Verstellung der Radialkolbenmaschine eine Schwenkbewegung um eine seiner Symmetrieachsen (Q,H) ermöglicht. Die Verstelleinrichtung (22) hierzu ist achsparallel zum Hubring (19) angeordnet.
Im Rotor (11) ausgebildete Arbeitskolben (13) führen pro Umdrehung des Rotors (11) zwei gleichartige, jedoch entgegengesetzt gerichtete Hubbewegungen über jeweils 180 Winkelgrad aus. Einander gegenüberliegende Zylinder (12) sind dabei mit identischem Druckniveau beaufschlagt und halten sich das Kräftegleichgewicht.
Der Rotor (11) rotiert somit weitgehend reibungsfrei.

摘要： The invention relates to a piston pump with suction regulation, especially for motor vehicles, and preferably with a control stub for internal admission. It is the purpose of the invention to provide such a pump with a constant supply flow rate over a wide revolution speed range and the lowest possible losses and low noise level. To this end the present invention proposes several solutions. In a first, the control slot (13) on the pressure side is divided into several grooves (27, 28), which are at least partly connected to the pressure link (20) via non-return valves (32). In another, the shape of the control slot on the pressure side is adapted to the optimum operating mode by making its inlet end relatively narrow to reduce the noise level (noise reduction at high revolution speeds) and keeping an adequate width at the outlet end for the power required. In a third, the arrangement for the slot (12) on the intake side is similar to that of the second solution and its length also affects the degree of filling of the piston drilling.

摘要： The fuel injection pump has a fixed pump body (12) with a pumping chamber (20) having a plurality of plunger bores (16), a plunger (14) mounted in each plunger bore (16) for reciprocation, a cam (60) rotatable for reciprocating the plungers (14) to periodically supply an intake charge of fuel to the pumping chamber (20) and deliver a high pressure charge of fuel from the pumping chamber (20) for fuel injection and to sequentially position the plungers (14) in distributor valve positions thereof to deliver the high pressure charges of fuel, via distributor ports (70) in the plunger bores (16), to a plurality of distributor outlets (45). In one version of the pump, the plunger bores (16) are angularly spaced about and extend radially inwardly to a central coaxial bore (104), the rotary cam (60) is an annular cam which actuates the plungers (16) inwardly to deliver the high pressure charges of fuel, and a poppet valve (100) is mounted in the central coaxial bore (104) to supply fuel to and spill fuel from the pumping chamber (20). A pressure regulator (20) has a fuel inlet opening (162) in axial alignment with the poppet valve (100) and which is closed by the poppet valve (100) in its open position to increase the rate of fuel supply to the pumping chamber (20).
