摘要：
The present invention relates to a servo-control (1) provided with at least one body (2) defining an inside space (10) together with a slider element (11) having a control piston (12) suitable for sliding in said inside space (10), said control piston (12) subdividing said inside space (10) into a retraction chamber (4) and an extension chamber (3). The servo-control (1) has at least one limit force detector device (20) comprising a casing (21) secured to said body (2) and defining a detection space (22). Furthermore, a movable member (50) subdivides said detection space (22) into a first detection chamber (26) opening out to said inside space (10) and a second detection chamber (27). Finally, the device includes detector means (29) for detecting the position of said movable member (50) in said detection space (22).
