Abstract

A hydraulic motor with roller elements 30 on the end of its pistons 16 acting on a cam ring 2. In order to combine a hydrostatic bearing for the roller elements with a compact structure each piston is made as a sleeve forming the working chamber of each cylinder and reciprocating in an annular chamber 45 surrounding the pressure medium inlet 34. Each piston has a groove 20 acting as a distributor valve controlling working liquid flow to and from another of the pistons. <IMAGE>
