摘要

The rotary engine has toroidal working chambers, where an outer chamber is formed from an intermediate ring-upper part (10), an intermediate ring-lower part and an outer ring (9). The inner chamber is formed from an inner ring (12) that is concentrically arranged to the outer ring. The rotation force-transmission is possible between the outer ring and inner ring by fluid-mechanically connected boreholes in a transmission part.
