摘要

Rotating piston combustion engine comprises an outer ring (2) pressed into a piston (1). The cylindrical contact surface (4) between the piston and the outer ring has openings (5) to allow gas to pass from one planar surface of the piston to another. Preferred Features: The diameter of the contact surface coincides with the diameter of the teeth of a toothed structure in the region of the tooth heads. The contact surface is additionally reduced using grooves in the piston.
