摘要： A high-pressure fuel pump having at least one pump element is driven by a camshaft. An inside chamber of the pump housing, together with the cam-shaped portion of the camshaft and a blocking vane, forms a blocking-vane pump, which can act as a prefeed pump for the at least one pump element, whereby a prefeed pump can be integrated with the high-pressure fuel pump, which saves both production costs and installation space.

摘要： A self priming pump system that includes a motor coupled to a centrifugal pump for driving the centrifugal pump. A separator having a reservoir is provided for storing a limited amount of pumped fluid in advance of the centrifugal pump. A vacuum source provides a vacuum suction to the reservoir to draw pumped fluid into the reservoir to prime the pump. To increase the reliability of the vacuum pump system, a deflector and/or extension may be provided in the reservoir to help prevent pumped fluid from entering the vacuum pump input. Also, the configuration of a tank used to store liquid for the vacuum pump system may be configured to separate and collect sediments near a drain port, which then can be easily drained. For positive head pressures, one or more valves may be used to prevent pumped fluid from escaping the reservoir, if desired.

摘要： A pump assembly which comprises a vane pump and a second hydraulic pump driven together with this vane pump. The vane pump has a suction region in which first pressure spaces between the vanes and second, rear pressure spaces behind the vanes become larger and a pressure region in which the pressure spaces become smaller and in which the pressure spaces are fluidically connected to a pressure outlet. This vane pump is intended particularly for supplying operating cylinders of a hydromechanical transmission of a motor vehicle with pressure fluid under relatively high pressure. The second hydraulic pump has positively driven displacement elements and is intended for supplying a circuit having a relatively low system pressure, in particular a lubricating-oil circuit of the motor vehicle, with pressure fluid. So that the vane pump also begins to deliver at low outside temperatures and with highly viscous pressure fluid even at low rotational drive speeds, the rear pressure spaces of the vane pump are connected in the suction region to the pressure outlet of the second hydraulic pump.

摘要： A first pump includes inner and outer intermeshing rotors, the outer rotor formed with external gear teeth. A second pump includes inner and outer meshing rotors, the outer rotor of the second pump having teeth continually engaged with the external teeth of the first pump outer rotor. The inner and outer rotors are formed with mutually intermeshing lobes that define between them pumping chambers through which hydraulic fluid is moved from a suction inlet to a pressurized outlet. A third pumping element includes pumping chambers located in the spaces between the intermeshing involute gear teeth on the outer rotors of the first and second pumps. A passage plate defines suction and pressure passages, which carry hydraulic fluid from a reservoir or sump to outlet ports, through which fluid is supplied to the hydraulic system.
