A hydraulic clamping element (1) has a housing (2) which is provided, on an end face (5), with an annular piston (6) which can move in the axial direction of the housing (2) and which delimits an annular space (17) formed in the housing (2). A pressure chamber of which the volume can be varied by turning the pressure screw (4) is formed in a bore (18) of the housing (2). The pressure screw (4) has, over a lengthwise portion, a radial spacing from the wall of the bore (18), with the result that a first pressure chamber (33) is formed. The pressure screw (4) is provided with a pressure ring (25), and at an axial distance thereto there is provided a screw portion (32) having an external thread (321) which interacts with a thread (20') belonging to the housing. A terminal end (32'') of the pressure screw (4) delimits a second pressure chamber (37), and the first and second pressure chambers (33, 37) and the piston space (17) are fluidically connected to one another. |
