Abstract

Un conjunto mejorado de válvula para sistema de fluido a presión en el que hay una tobera de presión conectada a una bomba, con una primera tobera de utilización que está en comunicación con un acumulador de presión y con un primer componente de utilización y que es conectable a la tobera de presión a través de un estrangulador y una válvula de derivación ("by-pass valve") la cual tiene un pistón de derivación cuya superficie efectiva adaptada para ser sometida a presión y cuya superficie efectiva adaptada para ser sometida a presión en el sentido de su cierre (y la cual se prolonga por el interior de una cámara de control) conectada con la tobera de presión a través de un estrangulador y de una válvula piloto de respuesta a la presión de un acumulador cuando esta presión del acumulador es inferior a un predeterminado límite y conecta con un conducto de retorno cuando la presión del acumulador ha alcanzado un predeterminado límite, caracterizado porque una tercera tobera de utilización a laque está conectado un tercer componente de utilización de centro cerrado es conectable a la tobera de presión por un conducto adaptado para ser cerrado por una válvula de control cuyo paso de válvula se abre cuando el tercer componente de utilización demanda fluido.
