Abstract:
The invention relates to an actuator cylinder, which is intended to be operated using a control valve (10) controlled by an operating lever (11). The actuator cylinder includes a cylinder barrel (13), a piston (14), and a rod (15), which extends outside the cylinder barrel (13). A detector element (18) is fitted in connection with the rod (15), its angle of rotation corresponding to the current position of the piston (14). The control valve (10) includes a rotatably supported slide construction (39), to which the detector element (18) is connected in order to rotate the slide construction (39) to a free-circulation position, when the piston (14) is in a position according to the operating lever (11). The control valve (10) also includes connections (24, 25), between which a through-flow channel (40) is arranged. The slide construction additionally includes a component (27) shutting off the said through-flow channel (40).
