ABSTRACT:
A unitary apex seal assembly for rotary engines. The assembly includes a pair of spaced bolts each adapted to engage a respective side wall of the rotor-containing chamber of the engine. Each bolt has a generally radially extending slot, and each slot includes an enlarged seal-retaining portion. A spring is interposed between the bolts and connected to both, and is further adapted to urge the bolts away from each other when installed in a rotary engine. An apex seal is received in the slots of both of the bolts, and includes an enlarged section within the enlarged seal-retaining portion of each of the slots. The seal is provided with a raised surface located between the bolts for precluding substantial axial relative movement between the bolts and the seal, so that the seal and appurtenances can be installed within a rotor as a single assembly.
