Abstract

CE ROBINET EST DU TYPE COMPRENANT DEUX SOUPAPES DOUBLES DISPOSEES L'UNE DERRIERE L'AUTRE ET UN PISTON D'EQUILIBRAGE. SELON L'INVENTION, LE PISTON 6 COMMANDE PAR LA TIGE 2 PAR L'INTERMEDIAIRE DU RESSORT DE COURSE 5 S'APPUIE SUR LE PISTON D'EQUILIBRAGE 17 PAR UN RESSORT DE RAPPEL 18; ENTRE LE PISTON D'EQUILIBRAGE 17 ET UNE CLOISON FIXE 1 SOLIDAIRE DU CORPS 1 DU ROBINET EST DISPOSE UN RESSORT D'AVANCE 30 QUI AGIT EN PERMANENCE SUR LE PISTON D'EQUILIBRAGE 17 ET QUI EST PLUS FORT QUE LE RESSORT DE RAPPEL 18.THIS VALVE IS OF THE TYPE INCLUDING TWO DOUBLE VALVES ARRANGED ONE BEHIND THE OTHER AND A BALANCING PISTON. ACCORDING TO THE INVENTION, THE PISTON 6 CONTROLLED BY THE ROD 2 THROUGH THE RUNNING SPRING 5 IS BASED ON THE BALANCING PISTON 17 BY A RETURN SPRING 18; BETWEEN THE BALANCING PISTON 17 AND A FIXED BULKHEAD 1 FIXED WITH THE BODY 1 OF THE VALVE IS A FEED SPRING 30 WHICH ACTS PERMANENTLY ON THE BALANCING PISTON 17 AND WHICH IS STRONGER THAN THE RETURN SPRING 18.
