SERVOACTUATOR WITH LIMIT EFFORT DETECTION

摘要

A limit force detector device (20) detects a limit force. The detector device has a casing (21) secured to a structure (2) and defining a detection space. A movable element (50) is slidable in detection space, the movable element subdividing detection space into a right detection chamber (26) opening out to an inside space (10) and a left detection chamber (27). A detector unit (29) detects position of movable element in detection space to determine whether movable element has reached a predetermined limit position corresponding to presence of a limit force exerted on servo-control.
