    摘要： 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).

    摘要： The invention relates to a frame for a water-jet propulsion unit, which is arranged to be installed and sealed into an installation opening (14) for a water-jet propulsion unit (16) belonging to a boat (12), which frame (15) includes a flow channel (26) for guiding water to the impeller (24) belonging to the water-jet propulsion unit (16), a maintenance opening (28) located on top of the said flow channel (26), for servicing the impeller (24), and a sealing surface (33) forming a closed loop for attaching the water-jet propulsion unit (16) tightly to the counter-sealing surface (32) belonging to the boat (12). The frame (15) includes, in addition, an additional sealing surface (34) for forming a second closed loop arranged to be. used in attaching the water-jet propulsion unit (16) to the boat (12), in such a way that the maintenance opening (28) of the, frame (15) is situated alternatively inside or outside the stern (44) belonging to the boat (12). The invention also relates to a corresponding water-jet propulsion unit equipped with the frame of a water-jet propulsion unit, and an arrangement in. a boat.
