Les éraflures des pistons de l'accumulateur et l'usure des alésages sont des problèmes courants dans les corps de vanne répertoriés, en particulier lors du fonctionnement à des pressions élevées. Les pistons des accumulateurs d'origine ont deux bagues d'étanchéité. La rainure d'étanchéité à l'extrémité ouverte du piston a un diamètre plus grand, la bague d'étanchéité agissant comme un guide pour empêcher le contact entre le piston et l'alésage. La rainure d'étanchéité à l'extrémité fermée du piston a un diamètre plus petit et la bague d'étanchéité agit comme un joint classique. Cependant, en raison du diamètre plus petit de la rainure du joint, le piston entrera en contact avec l'alésage lorsqu'il sera chargé latéralement, ce qui entraînera des éraflures, une usure et une fuite de la pression d'application de l'embrayage.
Notre kit de piston accumulateur de billettes 68RFE comprend deux bagues d'étanchéité de guidage, une à chaque extrémité du piston pour éviter les éraflures du piston à l'alésage lorsqu'il est chargé latéralement. De plus, l'emplacement de la bague d'étanchéité à l'huile est déplacé sur le piston, lui permettant de fonctionner dans une partie non usée de l'alésage, permettant ainsi de récupérer les alésages présentant des éraflures modérées.
