Circulating rotary piston fluid gas vapor pressure engine of trochoidal type has two stroke operation working on gas such as nitrogen

摘要

A rotary piston fluid gas vapor pressure engine of trochoidal type comprises a circulating convex piston (2) in a housing (1), vapor expansion chambers (10,11), an exhaust chamber, fluid gas drive inlet nozzles (14) inlet valves (5) for hot material and side outlets (6). An axial eccentric shaft (3) transmits force from the rotation and the operation is two-stroke.
