ABSTRACT:
A radial cylinder hydraulic pump or motor has radial pistons each provided with a guide pad urged against the cylindrical inner surface of a guide element. A continuous series of rollers cover the cylindrical inner surface and are interposed between such surface and the guide pads. The rollers are prevented from coming in contact with each other by a number of auxiliary smaller rollers. Between each piston and its respective guide pad there is interposed a sliding member which is slidably mounted on the pad along a tangential direction.
