<p>The clamping device includes a rotating clamping cylinder (1) and therein a clamping piston (2) and a distributor (4) which comprises a distributor housing (5) carrying connections (6) for the operating medium and a distributor shaft (7) which is coaxially connected to the cylinder housing (1.1). The distributor housing (5) is so arranged that the distributor shaft (7) can rotate therein. The distributor shaft (7) has two shaft ducts (18, 19) which communicates with the connections (6) on the housing and which lead into the clamping cylinder (1) on opposite sides of the clamping piston (2). Associated with each shaft duct (18, 19) is a check valve (20, 21) for controlling the through-flow. The check valves (20, 21) are disposed in the peripheral wall (1.2) of the cylinder housing (1.1) with the directions of displacement of the valve members (32, 33) and the control pistons (26, 27) being parallel to the axis (16) of the cylinder. <IMAGE></p> |
