Title (EN) RELAY VALVE AND FORCE BALANCING METHOD
(FR) SOUPAPE DE RELAIS ET PROCÉDÉ D'ÉQUILIBRAGE DE FORCE
Abstract:
(EN) A relay valve configured according to the various embodiments as described herein advantageously provides consistent, reliable start point pressures for both supply and exhaust functionalities. To achieve this, the relay valves described herein utilize a plurality of diaphragms to neutralize any variable forces due to pressure in an actuator and, optionally, a supply connected to the relay valve.
(FR) La présente invention, selon les divers modes de réalisation, concerne une soupape de relais fournissant avantageusement des pressions de point de départ constantes et fiables pour des fonctionnalités à la fois d'alimentation et d'échappement. À cet effet, les soupapes de relais selon l'invention font appel à une pluralité de membranes pour neutraliser de quelconques forces variables dues à une pression dans un actionneur et, éventuellement, à une alimentation connectée à la soupape de relais.
