ABSTRACT:
Sealing rings located in an annular recess about a piston in a Stirling engine have a continuous sealing ring of polymeric material having an L-shaped cross-section producing an annular flange abutment. A second discontinuous polymeric ring has a surrounding resilient steel strip resting against the abutment so that internal pressure cooperates with the two rings to effect a seal.
