Abstract

Un dispositivo de válvula de reducción de presión del tipo que comprende una válvula, una cámara de expansión dispuesta aguas abajo de la válvula con relación a la tubería de salida de gas, estando formada al menos una pared de esta cámara por una membrana flexible y desplazable, estando conectada la membrana al miembro de válvula de tal manera que una elevación de la presión de la cámara de expansión tienda a hacer que se cierre la válvula, caracterizado porque una cámara de transferencia auxiliar que comprende al menos un elemento de pared movible, está dispuesta en un circuito de gas entre la válvula y la cámara de expansión, estando conectadas las dos cámaras por una comunicación de caída de presión, estando conectado dicho elemento de pared al miembro de válvula, originando la caída de presión creada por dicha comunicación una presión diferencial que ejerce constantemente sobre el miembro de válvula una fuerza de apertura auxiliar, proporcional al caudal de descarga que pasa a través de él.
