The invention relates to a device for displacing and locking movable switch parts ( 1 ), comprising a hydraulic piston, which is formed by a rod ( 6 ) and cooperates, via coupling or locking members ( 8 ), with an axially displaceable sleeve ( 5 ) intended to receive the radially displaceable coupling or locking members ( 8 ), The displaceable sleeve ( 5 ) is coupled with the movable switch parts ( 1 ) and an externally arranged tube ( 4 ), at least partly overlapping the sleeve ( 5 ) and the rod ( 6 ). A hydraulic duct ( 11 ) is connected to the externally arranged tube ( 4 ), on a front face of the sleeve ( 5 ), facing away from the coupling site for the movable switch parts ( 1 ). |
