PISTON SERVO-ACTUATION MAIN SYSTEM WITH HYDROMECHANICALLY SELF-CONTAINED DETECTION |
摘要 |
Main piston servo-actuation system with hydromechanic self-contained failure detection device, working with hydraulic fluid supplied by a pump, including two servovalves (1 and 2) which are identical in design, controlli ng a piston (3) mechanically linked to a position transducer (4) according to the electrical demand supplied by the feedback position control loops (5 and 6) for the servovalves (1 and 2) to the torque motors (7 and 8) of the servovalves. These loops (5 and 6) receive the same piston position request, and they are given feedback at the same time with the same position signal fed by the position transductor 84). The system is furthermore competed by two pressure selection valves (9 and 10) and by its own interconnection servo lines.</SDO AB>
