ABSTRACT:
A seal mechanism for the periphery of the rotor of a rotary piston engine including a sealing ledge supported on the rotor to be pivotable about an axis extending in the longitudinal directional thereof and operative to make sealing contact with an opposed surface of said rotary piston engine over a limited region of the periphery of the sealing ledge facing toward said opposed surface. Through at least one secondary member extending parallel to the sealing ledge at a point of its periphery between the sealing ledge and the rotor, a surface region is defined on the sealing ledge at which forces are developed by the fluid working medium of the engine to effect a desired sealing engagement between the sealing ledge and the opposed surface of the engine.
