Abstract

Un compresseur (50) possède un actuateur (52) pour mouvoir le piston (58) dans un cylindre de compression (56). Un dispositif électromagnétique (76) comporte un noyau (77) et une bobine (80). Le noyau comporte une surface (104) et un canal (90). La bobine est disposée dans le canal. L'armature à déplacement axial (78) est en liaison mécanique avec le piston animé d'une course axiale avec milieu et fin de course. La surface (94) de l'armature est dimensionnée pour s'aligner avec la surface de l'électro-aimant lorsque le piston se trouve au sommet de sa course. Un ressort primaire (84) situé à l'une de ses extrémités, s'oppose au mouvement axial de l'armature dans une première direction. Un ressort secondaire (86), situé à l'autre extrémité de l'armature, s'oppose au mouvement axial de l'armature dans une direction opposée. Les ressorts contraignent l'armature à un mouvement de résonnance à une fréquence prédéterminée. L'application de courant en milieu de course du piston maintient la fréquence de résonnance, et permet d'éliminer les pertes dues au frottement et les forces de compression. Le montage de deux actuateurs dos-à-dos crée un compresseur à deux pistons.
