Abstract

Sistema principal de servo-actuación de pistón con sistema de actuación de fallos, que comprende dos servo-válvulas (1 y 2), y un pistón (4) unido mecánicamente a un transductor de posición (5). Las servoválvulas (1 y 2) reciben la misma presión desde la línea de alimentación (12) y descargan a la misma línea de retorno (13) y van conectadas al pistón (4) a través de un sistema de canalizaciones (3) para su posicionamiento en función de la demanda eléctrica transmitida por lazos realimentados de control de posición (6 y 7) a los motores de par (8 y 9) de las servo-válvulas, todo ello de modo que si el movimiento del pistón (4) no sigue la demanda solicitada a las servoválvulas (1 y 2), la lógica del sistema detectará la existencia de fallo, realizando el cambio a un sistema de respaldo.
