Abstract
An internal axis crankless rotary piston engine with an internal rotor and an external rotor mounted eccentrically to one another, with a circularly curved path of the external rotor mounting surrounding an internal rotor shaft, wherein the path of an external rotor bearing is mounted by a plurality of bearings which are spaced from one another in the direction of movement and which are fixed relative to the geometrical axis of the internal rotor shaft.
Claims7
An internal axis crankless rotary piston engine comprising:
- an engine casing (2, 65);
- an internal rotor (4') and an external rotor (18') eccentrically mounted within said casing (2, 65) for rotation about axes which are fixed relative to said casing;
- external rotor mounting means (60, 58) including circularly curved ring bearing means (58) rotatively mounting said external rotor;
- an internal rotor shaft (6') on said internal rotor (4') rotatively mounted relative to said casing (2, 65);
- said circularly curved ring bearing means (60, 58) of said external rotor mounting means surrounding said internal rotor shaft and being mounted by a plurality of individual bearing means (52, 53, 54) which are spaced from one another circumferentially relative to the ring bearing means (60, 58) within said ring bearing means (60, 58) and which are fixed relative to said casing (60, 58).
