Abstract

A hydraulic rotary piston machine, in which an outer toothed gear wheel cooperates with an inner toothed gear ring, the teeth of which are formed by rollers arranged in recesses of an outer ring and supported on lateral parts joined with said outer ring, characterized because the rollers are loosely arranged in the recesses, and because a sealing slide conducted on the outer ring presses against the periphery of each roller.
