摘要

A Stirling engine with mechanical output through a crankshaft (71) has piston(s) (44) reciprocable in cylinder bore(s) (41). The piston to crankshaft connection includes a lever arm (74) on pivot pin (77) and a connecting rod (75). The lever arm passes through opening (76) which is sealed from the engine crankcase by an annular seal member (94) engaged against part spherical seat (91) on the lever arm by gas pressure and by a spring washer (95).
