Title (EN) BALANCED REGULATOR WITH TARGETED BOOST SENSING TUBE
(FR) RÉGULATEUR ÉQUILIBRÉ À TUBE DE DÉTECTION À AMPLIFICATION CIBLÉE
Abstract:
(EN) A balanced port pressure regulator includes a valve body having a fluid inlet and a fluid outlet connected by a fluid passageway, an orifice being disposed between the fluid inlet and the fluid outlet. A valve seat is disposed within the fluid passageway. A valve plug is also disposed within the fluid passageway. A piston is disposed within the valve body, the piston separating the fluid passageway from a balancing chamber. A sleeve extends away from the piston, the sleeve forming a balancing passage that fluidly connects the fluid passageway with the balancing chamber. The sleeve includes an open end that terminates within the orifice. By terminating within the orifice, the open end of the sleeve generates boost only towards the end of a valve opening cycle when the valve plug approaches a fully open position, which is where boost is most needed.
(FR) La présente invention concerne un régulateur de pression d'orifice équilibré comprenant un corps de soupape présentant une entrée de fluide et une sortie de fluide raccordées par un passage de fluide, un orifice étant disposé entre l'entrée de fluide et la sortie de fluide. Un siège de soupape est disposé à l'intérieur du passage de fluide. Un bouchon de soupape est également disposé à l'intérieur du passage de fluide. Un piston est disposé dans le corps de soupape, le piston séparant le passage de fluide d'une chambre d'équilibrage. Un manchon s'étend à distance du piston, le manchon formant un passage d'équilibrage qui raccorde fluidiquement le passage de fluide à la chambre d'équilibrage. Le manchon comprend une extrémité ouverte qui se termine à l'intérieur de l'orifice. En se terminant dans l'orifice, l'extrémité ouverte du manchon génère l'amplification uniquement vers l'extrémité d'un cycle d'ouverture de soupape lorsque le bouchon de soupape s'approche d'une position complètement ouverte, qui est l'endroit où l'amplification est la plus nécessaire.
