ABSTRACT:
A regenerator for a Vuilleumier heat pump comprises a hollow body having an internal surface and a heat absorbing/emitting member housed within the body. In order to prevent leakage of fluid between the internal surface of the body and an outer periphery of the heat absorbing/emitting member, a flow interrupting structure is provided. One form of the flow interrupting structure involves grooves formed in the internal surface of the body, and elastic rings mounted in the grooves for contacting the heat absorbing/emitting member. Another form of the flow interrupting structure involves a wavy configuration of the internal surface and a corresponding wavy configuration of the outer periphery of the heat absorbing/emitting member.
