Abstract

Un clapet de refoulement présente une ouverture et une communication de fluide entre la chambre de compression et une poche d'aisance est établie sélectivement par un plongeur coulissant. Dans une première position, le plongeur remplit l'ouverture du clapet de refoulement pour couper la communication de fluide entre la poche d'aisance et la chambre de compressionet dans une seconde, il s'écarte du clapet pour établir une communication de fluide entre la chambre de compression et la poche d'aisance.
