ABSTRACT:
A seal system in a rotary engine includes apex seals held against an inner peripheral wall surface of a rotor housing, seal rings disposed between the apex seals and a side wall surface of the rotor housing, seal rings disposed between sliding plates mounted on a rotor and the side housing member, a split seal ring disposed between the side housing member and the rotor, and an air seal unit for supplying a flow of compressed air across a clearance between the rotor and the rotor housing to prevent gas leakage between compression and combustion stroke chambers.
