Abstract (en)
[origin: FR2914951A1] The device (80) has a double direction electrovalve (81) for opening or closing a hydraulic fluid conduit (83) between an upper chamber (121) and a lower chamber (122) of an actuating cylinder (8). A position sensor (82) is provided at a level of the actuating cylinder and determines a position of a control rack (7) using a controller (84). The electrovalve has a check valve (85) preventing movement of a hydraulic fluid from the lower chamber to the upper chamber.
