Abstract

Una valvula de descarga automatica incluye un cuerpo con una entrada y una salida y un asiento de valvula en la salida. Existe un ensamble de piston que se puede mover en el cuerpo hacia y lejos del asiento de valvula para controlar el flujo desde la entrada a la salida. Existe una camara de presion en el cuerpo de valvula de descarga automatica que mantiene al ensamble de piston en su asiento de valvula. El ensamble de piston incluye un orificio de relleno que conecta a la camara de presion con la entrada del cuerpo. Existe una valvula de liberacion en el ensamble de piston para ventilar la camara de presion a la salida. El ensamble de piston incluye una guia y un piston unidos al mismo. Existe un sello que tiene una porcion de perimetro anular el cual se coloca entre las superficies confrontantes de la guia y el piston y el sello tiene una porcion interior anular colocada en el asiento de valvula de liberacion para formar un sello con una valvula de liberacion. La porcion interior de sello y la porcion de perimetro se conectan por la pluralidad de rebordes que se extienden radialmente que permiten un grado de movimiento relativo entre las porciones interior y de perimetro del sello.
