Abstract

Une soupape de commande dans un compresseur qui règle le déplacement de refoulement fondé sur la commande d'une inclinaison d'un plateau-came (22). Le compresseur comporte un passage d'alimentation (48) permettant de relier une chambre de refoulement (38) à une chambre de bielle (15). La soupape de commande (49) présente un corps de soupape (64). Un élément de réaction (70) réagit à la pression d'aspiration. Un premier élément de transmission (74) est placé entre l'élément de réaction (70) et le corps de soupape (64). Un solénoïde (62) fait face à l'élément de réaction (70) par rapport au corps de soupape (64). Le premier élément de transmission (74) relie l'élément de réaction (70) et le corps de soupape (64) afin de déplacer le corps de soupape (64) vers ou de l'éloigner de l'élément de réaction (70). Le dispositif de poussée (65) provoque l'ouverture complète du passage d'alimentation (48) par le corps de soupape (64) lorsque le solénoïde (62) n'est plus excité.
