ROTARY PISTON MACHINE, ESPECIALLY ROTARY ENGINE

摘要

A rotary piston machine comprises a housing (10); a piston chamber (12) defined in the housing (10) by a first sidewall (14), a second sidewall (16) and a peripheral wall (18) interconnecting the sidewalls; a rotary piston (28) having a first face (29) and a second face (30) and being rotatably mounted in the piston chamber (12), the first face (29) of the rotary piston (28) facing an interior (15) of the first sidewall (14) of the piston chamber (12) and the second face (30) of the rotary piston (28) facing an interior (17) of the second sidewall (16) of the piston chamber (12), and at least two working chambers (34) being formed between a peripheral surface (31) of the rotary piston (28) and the peripheral wall (18) of the piston chamber (12). Furthermore at least one first lateral seal (36, 37) is provided on the first and the second face (29, 30) of the rotary piston (28) and preferably at least one second lateral seal (38, 39, 40, 41) on the first and second face (29, 30) of the rotary piston (28), the at least one second lateral seal (38, 39, 40, 41) being radially arranged within the at least one first lateral seal (36, 38).
