ABSTRACT:
A displacer-type Stirling engine includes buffer space provided in back of a power piston, and a front chamber in which a small-diameter piston provided on an end of a displacer rod is reciprocated. The buffer space and the front chamber are communicated by a conduit so that a fluctuation in pressure which develops in the buffer space is used as an auxiliary power source for driving the displacer rod.
