ABSTRACT:
Rotary piston engine having a substantially polygonal rotor provided at each apex portion with an apex seal and corner seals. The corner seal is so arranged that it is forced under the gas pressure introduced in a space behind it toward the side housing. A filler member comprised of a non-rigid material such as a heat resistant rubber or a suitable composite material is provided in a clearance between the corner seal and an adjacent end of the apex seal so as to prevent gas leakage through the clearance.
