摘要： A radial piston machine has a cylindrical housing which encloses a rotary shaft formed with an eccentric. A plurality of stationary piston rods is connected to the inner wall of the housing and radially directed toward the shaft. The free ends of piston rods are provided with ball-and-socket joints permitting universal rotary movement of the pistons. Each piston slidably engages the inner wall of an assigned cylinder which at its bottom wall slidably engages the eccentric. In a modification, the spherical surface of the stationary ball joint directly engages the inner wall of the cylinder.

摘要： The hydraulic axial piston engine has a rotary shaft and a stationary control plate symmetrically connected to a two-piece housing supporting for rotation the shaft. Two stationary lifting cams are arranged opposite each other at the end walls of the housing around the shaft; two rotary cylinder blocks are supported for joint rotation on the shaft and each adjoins a face of the control plate; the end walls of the cylinder blocks facing the cams are provided with a plurality of uniformly distributed and axially directed blind bores for accommodating working pistons. The end walls in each blind bore has a through passage for working fluid and the control plate in the range of the passages has a plurality of uniformly distributed control openings connected alternately to two annular distributing channels formed in the plate, one of the channels being connected to an intake port and the other channel to a discharge port for the working fluid. The ends of the pistons are provided with thrust balls engaging the sinusoidal cam surface of the lifting cams.

摘要： The invention relates to a piston machine comprising a plurality of pistons and changeable piston displacement for varying the torque and speed. The pistons are connected via control bores and distributor passages in the distributor of the machine to a high pressure and low pressure connection. To reduce the displacement a switching valve is provided via which the inactive pistons are connected together via their distributor passages and also possibly subjected to an external very low servo pressure or tank pressure. This reduces the frictional losses, increases the efficiency and avoids flow losses of the valve.
