ABSTRACT:
A Stirling-cycle assembly comprises an engine with a displacer piston mounted in a cylinder and defining a compression compartment and an expansion compartment respectively of a gaseous working fluid. These compartments communicate via a heat exchanger associated with a hot source, a regenerator and a heat exchanger associated with a heat sink. The engine is coupled to a heat pump having the same structure, via a resonance tube acting as an oscillatory drive member. The displacer piston of the heat pump is associated with a return means, e.g. a rod mounted in sealing-tight relationship in a closedchamber disposed on the compression compartment side.
