Abstract

Perfeccionamientos en dispositivos de válvula para servomotores de fluido a presión, del tipo en los que la presión diferencial que actúa a través de una pared movible se controla por medio de un dispositivo de válvula seguidor situado dentro de la cavidad de una parte de cubo de la misma, cuyo dispositivo de válvula comprende una válvula de cuerpo flexible anular que tiene una pestaña exterior de montaje diseñada de forma que sea empujada a hacer contacto hermético con la pared de dicha cavidad del cubo y con un resalto exterior formado en la misma, teniendo además una pestaña de válvula interior que se ve normalmente empujada por medios elásticos para hacer contacto a tope con un primer asiento de válvula situado en un órgano de control con movimiento alternativo y que además está adaptada para hacer contacto con un segundo asiento de válvula provisto en un resalto interior formado en dicha cavidad del cubo al desplazarse dicho órgano de control hacia el interior, caracterizados porque sedotan tales dispositivos de un elemento de refuerzo que comprende un cuerpo generalmente anular adaptado para que mantenga la pestaña exterior de montaje del cuerpo flexible de la válvula en contacto con la pared y el resalto exterior de la cavidad del cubo, na pestaña vuelta hacia arriba formada en el extremo exterior de dicho cuerpo anular para sostener el muelle de recuperación de la válvula y una pestaña pendiente angularmente hacia el interior formada en el extremo interior de dicho cuerpo anular para sostener y centrar el resorte seguidor de la válvula.
