Abstract

Un accionador electrohidráulico de válvula que incluye; una carcasa de accionador; unos medios de piston/cremallera en la carcarsa con paredes que alternanlinealmente para efectuar movimientos lineales, definiendo las paredes alternativas una cámaracentral entre ellas y dos cámaras exteriores dentro de lacarcasa; un eje de salida en comunicacion con los medios de piston/cremallera para mover una válvula, efectuando el eje de salida movimientos rotacionales enrespuesta a los movimientoslineales de los medios de piston/cremallera; medios elásticos de retorno en cada una de las dos cámaras externas que enganchan lasparedes alternativas de los medios de piston/cremallera y las paredes interiores de extremo de la carcasa, empujandolos medios elásticos de retorno las paredes alternativas de los medios de piston/cremallera a una posicion cerrada; unos medios de bombeo; un recorrido de flujo interno primario para transferir fluidohidráulico desde los medios de bombeo a un primerorificio de salida y a la cámara central, haciendo el fluido hidráulico en la cámara central que los mediosde piston/cremallera se expandan en la carcasa para transmitir los movimientos lineales al eje de salida; y un sistema de válvula de solenoidea prueba de fallos que tiene un recorrido de flujo interno secundario que conecta con y se extiende desde el recorrido de flujo interno primario a un segundo orificio desalida que se abre a al menos una de las cámaras externas y unaválvula desolenoide normalmen te cerrada en el recorrido de flujo secundario que impide el flujoa través del recorrido de flujo interno secundario. A la pérdida de potencia que llega al accionador, la válvula de solenoide a prueba de fallos se abre parahacerpor ello que los medi os elásticos de retorno expulsen fluido hidráulico de la cámara central, a través de los recorridos de flujo internos primario ysecundario, a al menos una de las cámaras externas, de manera que los medios de piston/cremalleranse hagan volver a una p osicion cerrada para girar el eje desalida para mover la válvula.
