ABSTRACT:
Apex seals are installed in slots in the apexes of a rotor in a rotary engine. Each apex seal assembly includes an outer sealing member, an inner support member, a pair of side or end members, a pair of hollow cylindrical slotted corner seal members mounted in the corner recesses, a pair of solid cylindrical resilient inserts mounted in the corner seal members and a pair of underseal springs to urge the seal members outwardly towards the running surface. The apex seal and its slot are tilted with respect to the rotor lobe centerline. The sealing and support members have mating inclined surfaces which form an inclined interface which is spaced entirely outside of the outer cylindrical surface of the corner seal member.
