Abstract
A system for reproducing a dry friction torque applied to an actuator on a valve of a hydraulic line including a disc coupled to a power transmission shaft; a disc brake including a caliper mounted on a frame and plates adapted to be put into contact with the disc; and an electric actuator configured to control the force of application of the plates onto the disc so as to apply a controlled resistive torque to the power transmission shaft, is provided.
