Abstract
A displacer assembly for use with a thermal regenerative machine has a housing configured to receive a displacer therein. The displacer has a drive area formed by a rod portion of the displacer that extends through a hole in the housing to form a clearance seal therebetween. The housing and displacer form a sub-assembly that can be pre-assembled to provide a clearance seal prior to assembly with a linear drive motor. Another feature is provided by a fluid flow path extending centrally of the displacer rod, and in part along an outer peripheral surface of the rod adjacent a heat rejection region of the housing. Heat transference there along provides for a more efficient stirling thermodynamic cycle in response thereto.
