Abstract

Un tel robinet comprend deux soupapes séparées disposées l'une derrière l'autre dans un corps de robinet, une tige de poussoir pouvant être commandée de l'extérieur et agissant sur le clapet d'une première soupape, et un dispositif de commande pour deuxième soupape. Selon l'invention, un siège d'admission 14 de la première soupape 18 est prévu sur un piston étagé 16 qui peut être couple par l'intermédiaire d'un ressort de course à un poussoir de commande 3, sur lequel agit la tige de poussoir. Ce robinet est utilisable en particulier comme robinet de frein à deux cicuits pour freins à air comprimé à haute pression de véhicules automobiles.Such a valve comprises two separate valves arranged one behind the other in a valve body, a push rod which can be controlled from the outside and acts on the valve of a first valve, and a control device for the second. valve. According to the invention, an intake seat 14 of the first valve 18 is provided on a stepped piston 16 which can be coupled by means of a stroke spring to a control pusher 3, on which the control rod acts. pusher. This valve can be used in particular as a two-circuit brake valve for high-pressure compressed air brakes of motor vehicles.
