Abstract
Main piston servo-actuation system, with hydromechanic self-contained failure detection device, working with hydraulic fluid supplied by a pump, including two servovalves ( and ) which are identical in design, controlling a piston ( ) mechanically linked to a position transducer ( ) according to the electrical demand ( ) supplied by the feedback position control loops ( and ) for the servovalves ( and ) to the torque motors ( and ) of the servovalves. These loops ( and ) receive the same piston position request, and they are given feedback at the same time with the same position signal fed by the position transducer ( ). The system is furthermore compensated by two pressure selection valves ( and ) and by its own interconnection servo lines.
