Abstract

Conjunto de filtro (10) para filtrar un fluido tal como agua, incluyendo el conjunto (10) un alojamiento (12) que define un orificio de entrada (42), un orificio de salida (44) y una cámara (40) entre los mismos, un elemento de filtro operativo en uso para filtrar el fluido que fluye desde el orificio de entrada hasta el orificio de salida, un elemento de válvula (20) que presenta un eje (28), estando el conjunto configurado de manera que, en uso, el fluido fluya desde la parte exterior del elemento de filtro hacia el eje, siendo el elemento de válvula (20) por lo menos parcialmente recibible en la cámara (40) y móvil entre una posición abierta en la que se permite el flujo de fluido entre los orificios de entrada (42) y de salida (44) y una posición cerrada en la que sustancialmente se impide el flujo de fluido a través de cada uno de los orificios (42, 44), en el que el elemento de válvula (20) incluye un par de salientes de cierre (34, 36) operativos en uso de modo que, en la posición cerrada, cada uno de los salientes de cierre (34, 36) sustancialmente cierre un orificio respectivo (42, 44), en el que dicho elemento de válvula (20) incluye un par de primeras juntas de sellado (38), extendiéndose cada primera junta de sellado (38) alrededor de un saliente de cierre (34, 36) respectivo, en el que el elemento de válvula (20) define un canal de entrada (30) que, en uso, en la posición abierta, se dispone para recibir un flujo de entrada del orificio de entrada (42), definiendo el elemento de válvula un canal de salida (32) que, en uso, se dispone para dirigir un flujo de salida hacia el orificio de salida (44), estando dicho conjunto dispuesto para proporcionar una posición de purgado intermedia entre las posiciones abierta y cerrada, en el que el conjunto incluye un saliente de purgado (72) que se extiende sustancialmente desde la primera junta de sellado (38) que se extiende alrededor del saliente de cierre de entrada (34, 36) en una dirección opuesta a una dirección de movimiento hacia la posición abierta, caracterizado por que, en la posición de purgado intermedia, el saliente de purgado bloquea parcialmente el orificio de entrada, de manera que se permita un flujo de entrada reducido.
