Abstract
In the preferred embodiment, the device comprises a body, a sliding rod mounted to slide inside the body, and a control rod including both compression and expansion end-of-stroke abutments associated with a control piston for displacing the control rod to a position which is retracted or extended relative to the body. The stroke c of the sliding rod is greater than the distance d between the compression end-of-stroke abutment and an immediately adjacent end of the corresponding chamber when the control rod is in an extended position.
