Abstract
The seal bellows of a Stirling cycle device is connected between the bottom of a reciprocating piston and a cylinder wall to form a buffer space between the cycle working space and the lubricated crankcase. The piston and cylinder wall form a noncontact clearance seal between the buffer space and the working space in which an expander piston has a vented clearance seal to reduce the thermal loss due to cold gas leaking along the clearance seal.
