Abstract

Válvula de control de presión fluida del tipo que comprende un alojamiento, un colector en dicho alojamiento conectado a una fuente de presión fluida, una serie de cámaras valvulares conectadas en paralelo con el citado colector, una serie de cámaras de suministro conectadas a las respectivas cámaras valvulares, un elemento valvular normalmente cerrado que desconecta cada una de las cámaras valvulares respecto a su cámara de suministro, émbolos en alineamiento axial con dichos elementos valvulares, un árbol accionador dispuesto en relación transversal respecto a los citados émbolos y una empuñadura fijada al árbol accionador, caracterizada porque se incluyen en el citado árbol unas levas acoplables a los referidos émbolos, estando construidas y dispuestas las citadas levas de manera que, en una posición de la citada empuñadura, aquellas quedan desacopladas de los émbolos y los referidos elementos valvulares se encuentran en su posición normal cerrada; en una segunda posición, las citadas levas se acoplan por lo manos a uno de los referidos émbolos para abrir un elemento valvular; y n otra posición de la empuñadura, todos los émbolos se acoplan a alas levas para mover todos los citados elementos valvulares a su posición abierta, disponiéndose un resorte graduador entre uno por lo menos de los émbolos y las citadas levas; y un pistón sensible a presiones fluidas en dicha cámara de suministro, sometido a la presión admitida a través de su elemento valvular tras su apertura, para ejercer una fuerza presionadora sobre dicho pistón y desplazarlo a una posición en la que el referido elemento valvular se cierra cuando se ha admitido en la cámara de suministro una presión inferior a la del colector.
