Abstract
An adjustable radial piston machine (pump or motor) is described whose drive mechanism (10) has a comparatively compact structure and an especially good mechanical efficiency. The drive mechanism (10) has a bearing ring (19) which is arranged concentric to a rotor (11) and which can be swung or pivoted about a symmetry axis (Q,H) different from its rotation axis for adjustment of the radial piston machine. An adjusting device (22) for pivoting the bearing ring extends axially parallel to the bearing ring (19) and acts on a facing surface of the bearing ring (19). Working pistons (13) guided in the cylinders in the rotor perform two motion cycles per revolution of the rotor, which are equal, but in opposite directions, over respective 180.degree. angular intervals. Cylinders (12) on opposite sides of the rotor are acted on by identical pressures so that the forces on the rotor are balanced and the rotor rotates largely free of friction.
