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 an outer cylinder. Each section of the shaft has two helical grooves (19, 20, 23, 24). The piston has two pins (21, 22) which run in one set of grooves. A sleeve (14) which drives the plunger has pins (25, 26) running in the second set of grooves. Dispositif à cycle Stirling. Le dispositif à cycle Stirling comprend un compresseur alternatif ou un moyen de déplacement agissant sur un fluide de travail, un arbre rotatif, et un moyen d'entraînement pour effectuer la transformation du mouvement rotatif de l'arbre rotatif au compresseur ou au moyen de déplacement, le moyen d'entraînement comprenant une piste à came ondulatoire annulaire et un galet de came, l'un étant associé à l'arbre et l'autre étant associé au compresseur ou au moyen de déplacement. Application aux générateurs de force motrice et aux pompes à chaleur.
