Internal axis rotary piston engine with protrusions having two sealing corners

摘要

In a rotary piston engine which can be produced by simple manufacturing techniques and which has an outer and an inner rotor which rotate in a housing about different axes of rotation, wherein strip-like projections on inwardly extending engagement members generate the contour of the piston of the inner rotor, whereby a well-defined contact seal can be realized in use, the projections have two sealing corners adjacent to but spaced from one another in the direction of rotation of the outer rotor.
