摘要： A motor pump unit for a high-pressure cleaning apparatus has an electric motor and a pump. The electric motor has a motor housing that is surrounded by a cooling housing with an annular space having an annular space inlet and an annular space outlet formed therebetween. The pump has a drive housing on which is supported the motor shaft, and has a suction inlet and a pressure outlet. The annular space outlet is fluidly connected to the suction inlet and liquid to be pressurized by the pump is suppliable to the annular space inlet. In order to improve the motor pump unit such that the heat load on the drive housing can be reduced, the drive housing has at least one cooling passage which is arranged upstream of the suction inlet and through which the liquid to be pressurized can flow.

摘要： A hydraulic power unit having a power shaft that rotates a cam. The cam actuates a piston assembly that contains a plurality of pistons wherein each piston has a piston body and fluid working chamber. An electrically actuated bypass valve is fluidly connected and in communication between an outlet check valve and a fluid working chamber of each piston such that when actuated the electrically actuated bypass valve directs fluid away from the outlet port into a reservoir to be returned to an inlet port.

摘要： A method for determining system parameters, such as the operating speed, working pressure and pivot angle of an axial piston unit in which the operating speed, working pressure and pivot angle are determined by means of a frequency analysis of a detected solid-borne sound signal from an axial piston unit of a hydrostatic drive mechanism. A liquid-borne sound signal of airborne sound signal can be used, in which case a respective system parameter is determined by means of a frequency analysis of a detected liquid-borne sound signal or airborne sound signal from the axial piston unit.

摘要： An axial plunger pump includes an auxiliary plate mounted to a cam plate at an end thereof on the side of a cylinder block to be rotatabe relative to the cam plate, and a flexible partition member interposed between a housing and the auxiliary plate to cover a drive shaft and the cam plate. The flexible partition member, which is in the form of, e.g. a metal bellows, serves to divide the inside of the housing into a working fluid chamber and a lubricant chamber.
