Abstract

Un tel appareil est actionné par une pression de commande qui est directement proportionnelle à une pression de réaction dans une chambre à pression variable prévue dans l'appareil et pouvant être mise en communication avec une conduite d'alimentation ou un point de décharge, et qui détermine la presdon de freinage dans au moins un cylindre de frein de roue. Selon l'invention, la chambre à pression variable 13 est délimitée par un diaphragme commutateur 12 qui est, soit, sous l'effet de la pression de commande (robinet de rein 2, conduite de commande 5), élément de commutation d'une soupape relais 9 ou d'une soupape de desserrage rapide 12/14, soit élement de contrôle d'une communication entre une canalisation 26, 27 menant à un cylindre de frein 24, 25 et l'air extérieur (orifice 32).
