PCT No. PCT/SE90/00251 Sec. 371 Date Oct. 8, 1992 Sec. 102(e) Date Oct. 8, 1992 PCT Filed Apr. 12, 1990 PCT Pub. No. WO91/16540 PCT Pub. Date Oct. 31, 1991.A rotary reciprocating engine has a rotating center shaft and a rotating outer rim with a rotational eccentricity in relation to the center shaft. The engine has a synchronization mechanism including a synchronizing hub, a guide rail, one cam member fitted to the center shaft, and another cam member fitted to the outer rim. The synchronization mechanism has the same rotational eccentricity in relation to the center shaft as the outer rim, but the rotational axes of the synchronization mechanism and the outer rim are on opposite sides of the rotational axis of the center shaft. The synchronization mechanism restrictively guides rotation of the center shaft and the outer rim, and transfers and balances the forces and moments generated by the pressure medium in the engine, leading to the pistons and cylinders being subjected to axially directed forces only and not moment transferring cross head forces. |
