Abstract

La presente invención se refiere a un sistema combinado de una válvula piloto de operación mecánica e hidráulica para una bomba de dos diafragmas, caracterizado porque comprende: en combinación; (a) una cubierta que define una primera y una segunda cámaras de presión hidráulica axialmente espaciadas en una bomba de dos diafragmas; (b) un primer y un segundo diafragmas dispuestos en la primera y en la segunda cámaras de presión, respectivamente, para definir una pared flexible en cada una de dichas cámaras de presión, cuyos diafragmas son generalmente transversales con respecto al eje, y los cuales se conectan mecánicamemnte para efectuar un movimiento alternativo generalmente simultáneo en la dirección axial, y cuyos diafragmas definen, cada uno de ellos, una pared flexible de una cámara de bombeo adyacente; (c) un montaje de válvula piloto que tiene una sola entrada para el fluido, una primera salida hacia la primera cámara y una segunda salida hacia la segunda cámara, cuyo montaje de válvula piloto incluye también una válvula deslizante alternativa de operación hidráulica para conectar la entrada con la primera o la segunda salidas; cuya válvula deslizante de operación hidráulica incluye un accionador hidráulico de área superficial diferencial que tiene un área superficial menor y un área superficial mayor, cuyo montaje incluye también un miembro piloto mecánicamente desplazable que se proyecta axialmente hacia el interior de las cámaras de presión y es axialmente deslizable en respuesta al contacto por uno de los diafragmas; (d) un primer y un segundo pasadizos de presión hidráulica del fluido que conducen hacia las áeas superficiales menor y mayor, respectivamente, del accionador; cuyo primer pasadizo de presión se comunica directamente con el área superficial menor, y el segundo pasadizo de presión se comunica, mediante el miembro piloto mecánicamente desplazable, con el área superficial mayor; (e) cuyo miembro piloto mecánicamente desplazable incluye un pasadizo de conexión del fluido que abre al segundo pasadizo para que fluya el fluido presurizado al efectuarse la inversión mecánica del miembro piloto axialmente hacia solamente uno de los diafragmas por contacto con el otro diafragma.
