Abstract

L'invention concerne un cylindre de commande (12; 12') pour un frein moteur destiné à fournir une fonction de ralentissement par étranglement du flux de gaz d'échappement du côté sortie d'un turbocompresseur (2) d'un moteur de véhicule (1), comprenant une chemise de cylindre (17) pour loger un piston (22) pourvu d'une tige de piston (21) pour subdiviser la chemise de cylindre (17) en une chambre de ressort (23) pour loger un ressort de rappel (25) pour la tige de piston (21) et une chambre de pression (24) pour produire une force d'actionnement de la part du piston (22) par air comprimé, une bague d'étanchéité dynamique (26) étant disposée radialement entre le piston (22) et le côté intérieur de la chemise de cylindre (17), d'autres moyens d'étanchéité statiques étant prévus en plus de la bague d'étanchéité dynamique (26) du piston (22) pour empêcher un écoulement de fuite de la chambre de pression (24) vers la chambre de ressort (23) pendant que la tige de piston (21) est en position finale sortie. L'invention concerne également un système de turbocompresseur pourvu d'un cylindre de commande selon l'invention.
