Abstract
Válvula de control de rebose accionable electromagnéticamente que incluye un elemento de válvula (14, 41) que puede deslizar en un agujero (12) en un cuerpo de válvula (11, 51), un asiento (13) en el agujero, estando configurado el elemento de válvula (14, 41) para la cooperación con el asiento, cámaras de entrada y salida (16, 17) definidas en lados opuestos del asiento (13), un inducido (30, 42) acoplado al elemento de válvula (14, 41), formando el inducido parte de un accionador electromagnético (48) que, cuando está excitado, arrastra el elemento de válvula (14,41) a enganche con el asiento para evitar el flujo de fluido entre las cámaras de entrada y salida (16, 17), medios elásticos (38, 47) que se oponen al desplazamiento del inducido, medios de tope (26, 26A, 52A) para determinar la cantidad de separación del elemento de válvula (14, 41) del asiento (13) bajo el empuje de los medios elásticos (38, 47) cuando el accionador (48) está desexcitado, medios amortiguadores (25, 52) que controlan dicho desplazamiento del elemento de válvula (14, 41) con lo que se minimiza el rebote del elemento de válvula (14, 41), caracterizada porque dichos medios amortiguadores los definen, en parte, el cuerpo de válvula (11, 51) y, en parte, dichos medios de tope (26, 26A, 52A) que cooperan con el cuerpo de válvula para limitar el desplazamiento del elemento de válvula.
