Abstract

A combination apex corner seal and side compression seal for rotary piston internal combustion engines, the combination consisting of wishbone shaped members having two legs diverging from an integral hub, the hub being shaped to form the end member of an apex seal, the legs of the wishbone indexing with grooves in the side of the piston and forming side compression seals.
