Abstract

La présente invention concerne un compresseur de type à pistons dans les blocs-cylindres (21, 23) duquel sont formés des premiers canaux de communication (37a, 41a) ou analogues reliés à des alésages de cylindre (35a, 39a) ou analogues. À l'intérieur d'un arbre d'entraînement (3) sont formés des canaux d'arbre (3a, 3b) qui s'étendent dans la direction axiale d'arbre d'entraînement (O) et des canaux de trajet (3c, 3e) qui s'étendent dans une direction radiale de l'arbre d'entraînement (3) en communication avec les canaux d'arbre (3a, 3b) et qui sont en communication intermittente avec les premiers canaux de communication (37a, 41a) ou analogues conjointement avec la rotation de l'arbre d'entraînement (3). Un corps mobile comprend : des bobines (55, 57) qui sont disposées à l'intérieur des canaux d'arbre (3a, 3b) de manière à être mobiles dans la direction axiale d'arbre d'entraînement (O) ; et des couvercles (63, 65) qui sont disposés dans les canaux de trajet (3c, 3e) de manière à venir en prise avec les bobines (55, 57) et qui sont susceptibles de changer des zones de communication par rapport aux canaux de trajet (3c, 3e), aux premiers canaux de communication (37a, 41a) et analogues. Les couvercles (63, 65) sont conçus pour maximiser les zones de communication lorsque le débit de décharge est à un niveau maximal et pour réduire au minimum les zones de communication lorsque le débit de décharge est à un niveau minimal.
