Abstract

L' invention concerne un servomoteur pneumatique d'assistance au freinage dans lequel une douille (103) qui coulisse dans un alésage du piston pneumatique (22) du servomoteur et dont une face annulaire arrière (105) est destinée à entrer en contact avec un joint annulaire de la vanne trois voies pour former un clapet d'équilibrage de pressions entre la chambre avant et la chambre arrière. Une clé de blocage (102, 102') mobile radialement par rapport à la douille (103) traverse la paroi périphérique de la douille (103). Le plongeur distributeur possède une face (460) inclinée qui commande, lorsque le distributeur plongeur (46) se déplace vers l'avant, le déplacement radial de la clé par rapport à la douille (103) ce qui permet à celle- ci de se déplacer vers l'arrière et ce qui tend à fermer ledit clapet d'équilibrage. Application: Freins pour véhicules automobiles.
