A device for buoy based wave power apparatus, where the bu- oy (30) coacts with a cylinder/piston arrangement which is connect- ed to the sea bed, and where the arrangement is provided with the valve means (34, 35) enabling fluid flow through a piston (32) and possibly a piston rod (33) in said arrangement, a pressure being formed in one chamber (37) of the arrangement during the upward movement of the buoy (30) and simultaneously a suction via a snor- kel or via focusing conduits/means (30', 44, 47) into that part of the cylinder which is adjacent the top face of the piston and which forms a second chamber (36). The piston rod (33) has mounted thereon a submarine buoy (29) or a sink member (80) and is articulated or flex- ibly (46) connected to a sea bed base member (40, 81). The cylinder (31) may be fixedly or articulated (68) connected with the buoy (30, 55, 67). The buoy (30) is provided with a cavity/vessel (42) receiving water upon bigger waves, and being drained through self-drainage conduits (43) during the return of the buoy into the trough of the wave. A linear induction generator can be arranged at the slide movement between an extended piston rod (85) and a guide tube (87) therefor which is arranged on the buoy (86).
