Abstract: An axial-piston machine of the type in which a prismatic housing, usually of rectangular or square cross section, receives a rotatable cylinder drum, the pistons of which bear against an inclinable control surface. The control surface is formed on a rocker or tilting box which can be tilted about an axis perpendicular to the axis of rotation of the drum. The rocker-setting elements are disposed between the housing bottom and the reaction surface of the rocker (against which the pistons bear), at the corners of a rectangle which closely circumscribes the orbit of the pistons. Consequently, the presence of the rocker-displacing means does not increase the dimensions of the machine over those necessary for a fixed control surface machine.

Abstract: A control device for an axial piston machine in which the rocker controlling the angular orientation of the cylinder drum is shifted by a differential-action setting piston having a pin which engages in the rocker. The opposite end of this pin bears via a pressure body on one arm of a bell crank lever which can have a curved camming surface, the pressure body including a roller and being urged by a first spring against the bell crank lever. The other arm of the bell crank lever is engaged on one side by a control piston subjected to the pump pressure while the valve member which controls the pressure to the large-diameter side of the setting piston engages the opposite side of the bell crank lever and is urged against this opposite side by a second spring.

Abstract: A piston for a hydrostatic piston machine, especially an axial-piston pump or motor in which the piston is formed with a ball head riding in a slide shoe which is supported by a fluid-pressure cushion against a countersurface, e.g. a swashplate. The piston is formed with a central passage which communicates with a bore in the ball head, this bore being provided with a throttle to prevent the fluid medium from being forced at an excessive rate into the fluid-pressure cushion and thereby lift the shoe from the countersurface. According to the invention, the end of the piston remote from the ball head is provided with a gap filter of large area and narrow gap width to prevent large particles from entering and blocking the passage and the throttle.

Abstract: A hollow piston for a hydrostatic piston machine and especially for a swash-plate-type axial-piston pump or motor, comprises a hollow outer cylinder member which is formed at one end with a ball head and at the other end with a cover. Extending centrally through this hollow piston is a central post having its opposite ends secured to or engaging the opposite ends of the outer piston member and formed with a central bore communicating between a passage in the cover and a passage in the ball head. At least one of these ends of the central post is juxtaposed with a respective end of the piston and the juxtaposed ends are formed with a conical surface and an edge engaging this surface to seal the post to the outer member.
