Abstract

The invention relates to a rotary piston engine of the type having an internally toothed ring and an externally toothed wheel which is orbitably and rotatably movable relative to the ring. The motor has a disk shaped valve which is driven by the externally toothed wheel through a universal joint shaft. In order that the shaft only applies torque to the valve, to the exclusion of any axially directed force, the valve has a splined bore and is journalled on a cylindrically shaped abutment which is fixed relative to the casing. The shaft has a splined head which engages the splined bore of the valve to effect rotation of the valve but the shaft head is in axial thrust engagement with the abutment so that no axial forces are transmitted to the valve. The valve and casing parts are appropriately and uniquely disigned with cooperating annular recesses so that axially directed hydraulic forces on the valve are also minimized. The overall result is that there is no mechanical axial loading of the valve and little or no hydraulic axial loading of the valve.
