Abstract

The system, with hydromechanic self-contained failure detection device, working with hydraulic fluid supplied by a pump, includes two servovalves (1,2), controlling a piston (3) mechanically linked to a position transducer (4) according to the electrical demand supplied by the feedback position control loops (8,9) for the servovalves to the torque motors (12,13) of the servovalves. The loops receive the same piston position request (10,11), and they are given feedback at the same time with the same position signal (5) fed by the position transducer. The system is furthermore completed by two pressure selection valves (14,15) and by its own interconnection servo lines.
