Abstract

Un actionneur de frein à ressort (10), pourvu d'un ressort de compression puissant (82) dans une deuxième chambre de ressort (78) du carter, comporte des évents (100) dans le carter communiquant avec la deuxième chambre de ressort (78). Un ensemble filtrant (134) recouvre les évents (100). Des trous d'évacuation (62), (104), (102) et (100) ménagés dans un manchon (50) d'une tige de poussée (18), dans une tige d'actionneur de frein à ressort (4), et dans une portion (68) du carter de frein à ressort permettent conjointement au fluide comprimé dans une première chambre de frein de service (30) de s'écouler, par l'intermédiaire d'un conduit défini par ces trous d'évacuation, hors de l'actionneur de frein (10) dans lequel il est filtré par l'ensemble filtrant (134).
