Abstract

Válvula reguladora de caudal, que comprende un estrechamiento de sección constante, dispuesto en un recorrido de circulación de fluido, un pistón principal de estrechamiento dispuesto en el citado recorrido, una de cuyas caras está sometida a la fuerza de un resorte, y la otra cara delimita una cámara de trabajo conectada por un canal de enlace con el cilindro de una válvula de descarga, constituida por un pistón auxiliar, una de cuyas caras está sometida, simultáneamente, al esfuerzo de un resorte auxiliar y a la fuerza que resulta de la presión de salida de la válvula, y cuya otra cara está sometida a la presión de mando de los desplazamientos del pistón principal en el sentido de la apertura del recorrido de circulación de fluido, caracterizada por el hecho de que el cilindro de la válvula de descarga está unido al ánima del pistón principal, por medio de un canal, que desemboca en dicha ánima, entre el orificio de entrada y el orificio de salida, aguas arriba del paso estrechado.
