The heat pump has a shaft which carries the rotor of an electric motor (3). A compressor piston (12) is driven by the large shaft section (15) and a plunger (7) is driven by the small section (16). The compressor forces gas through a heat exchanger (6) and through a regenerator within the plunger to...
