Title
(EN) PILOT OPERATED REGULATOR WITH ADJUSTABLE MINIMUM DELIVERY PRESSURE
(FR) RÉGULATEUR ACTIONNÉ PAR PILOTE À PRESSION DE REFOULEMENT MINIMALE RÉGLABLE
Abstract
(EN)
A regulator for establishing outlet fluid pressure. The regulator includes a valve body having a fluid pressure inlet in selective fluid communication with a fluid pressure outlet. A pilot pressure inlet is formed in the valve body and in fluid communication with a source of pilot pressure. Valving structure in the valve body establishes outlet fluid pressure as a function of pilot pressure. First adjustable structure within the valve body may establish a minimum outlet fluid pressure threshold without regard to pilot pressure. Second adjustable structure within the valve body may establish outlet fluid pressure offset relative to pilot pressure.

L’invention concerne un régulateur pour établir une pression de fluide de sortie. Le régulateur comprend un corps de soupape ayant une entrée de pression de fluide en communication fluidique sélective avec une sortie de pression de fluide. Une entrée de pression pilote est formée dans le corps de soupape et en communication fluidique avec une source de pression pilote. Une structure de soupape dans le corps de soupape établit une pression de fluide de sortie en fonction de la pression pilote. Une première structure réglable à l'intérieur du corps de soupape peut établir un seuil de pression de fluide de sortie minimal sans tenir compte de la pression pilote. Une seconde structure réglable à l'intérieur du corps de soupape peut établir un décalage de pression de fluide de sortie par rapport à la pression pilote.
