摘要： The invention relates to a hydrostatic piston machine. The hydrostatic piston machine comprises a housing in which a cylinder drum is rotatably arranged. A first group of cylinder bores and a second group of cylinder bores are arranged in the cylinder drum. Arranged longitudinally displaceably in the cylinder bores are respective pistons, which are supported on a swash plate which may be inclined about at least one swivelling axis. The first group of cylinder bores is temporarily connected to a first hydraulic circuit via first control slots (50, 51) of a control plate, when the cylinder drum is rotated. Accordingly, the cylinder bores of the second group are temporarily connected to a second hydraulic circuit via second control slots (57, 58) of the control plate (32′), when the cylinder drum is rotated. The relative position of the first and/or second control slots (50, 51; 57, 58) may be altered relative to the at least one swivelling axis of the swash plate.

摘要： A support structure carrying a thrust load of a compressor has a swash plate which contributes to a compressing operation by rotating according to rotation of a rotating shaft which is rotatably supported by a housing. The swash plate is rotatably supported with respect to the housing, and the support structure includes a thrust needle roller bearing having double-row needle rollers. The support structure carrying a thrust load of a compressor and the thrust needle roller bearing are thus obtained, with an improvement in inflow and outflow of a lubricating oil, a reduction of the differential slip of the needle rollers, and an improvement in strength durability.

摘要： A hydrostatic adjustment unit with a swash plate for adjusting the stroke of displacer pistons which are arranged in a rotating cylinder block is described. The displacer pistons each have a slider block which bears against a support face of the swash plate and is held in abutment by means of a slider block holder. The slider block-holder has a number of bores for receiving the slider blocks corresponding to the number of displacers. The slider block holder at the same time forms the rotor of a rotational speed signal transmitter for determining the rotational speed of the cylinder block.
