Compensated actuator with optimised power

摘要

The activator comprises a cylindrical body (20) and a piston (30) which slides in the body. The piston and body are connected by a screw-nut system which allows the transfer of mechanical energy and constitutes a permanent control device for positioning the piston. Hydraulic energy is supplied by a hydro-pneumatic accumulator (50) to a hydraulic piston (25).
