摘要： The hydrostatic piston machine has a smooth cylindrical pintle which is fixedly mounted in the housing and on which a cylinder block is rotatably mounted. The guide member for the pistons is eccentrically mounted about the pintle and has means thereon for supplying and/or taking off the torque of the machine. The eccentricity of this guide member is adjusted by a movable guide means within the housing. This guide means is controlled by the pressure mdium flowing through the machine.

摘要： The machine has a cylindrical pin mounted at each end in a guide device which is movable so as to change the eccentricity of the guide member axis relative to the pin axis. The guide member is connected over a toothing to a shaft for receiving or taking off power. The toothing can be formed on the outer periphery of the guide member or on a gearwheel secured to a side of the guide member. The guide device may either be of a pivotal type or a slidable type.

摘要： The guide member for the pistons is made of a guide ring and a pair of disc-shaped side parts. The mating bearing surfaces of the guide ring and each side part are disposed about a plane of symmetry which is coincident with the plane of symmetry of the bearing surface of side part on the pin. This avoids deformation of the guide member under high radial loads.

摘要： A radial piston machine has a rotor which turns within the confines of a surrounding annular control face and is provided with substantially radial cylinder bores each accommodating a radially slidable piston having an outer end provided with a piston shoe formed with guide portions projecting circumferentially of the rotor beyond the associated piston and having contact faces which are in sliding engagement with the control face. Each of the contact faces has a hydrostatic bearing constituted by a depression surrounded by a sealing land, and recesses are formed in the respective contact faces outwardly spaced from the sealing lands, so as to separate the latter from outwardly adjacent portions of the contact faces.

摘要： A radial piston pump or motor wherein the pistons are connected with the respective shoes by ball and socket joints and the shoes have convex faces travelling along a cylindrical track of the stationary slide block. The concave and convex surfaces of each joint define a hydrostatic relief chamber whose area is at least 70 percent of the cross-sectional area of the respective piston and the radius of curvature of each such concave and convex surface is at least 90 percent of the radius of the respective piston. The outer faces of the shoes define with the inner face of the slide block hydrostatic relief compartments each having an area which is at least 70 percent of the cross-sectional area of the respective piston. The chambers and compartments are connected with the cylinders for the respective pistons by way of channels which are machined into the pistons and shoes so that the pressurized fluid in the chambers and compartments greatly reduces friction between the pistons and shoes as well as between the shoes and the slide block.

摘要： A fluid pump or motor having a rotor with hollow radially directed piston spokes, each extending into a separate one of a plurality of cylinders which ride against an eccentrically positioned circular race, is provided with cylinders having an inside diameter which progressively decreases towards the radially innermost end of the cylinders to compensate for expansion of the cylinder walls in the course of each working stroke when operated under extreme high pressures. Problems with excessive wear or leakage at the zone of contact between the cylinders and pistons are thereby alleviated.
