The holding device has a housing (5) and a rotatable shaft (6) projecting from the housing, the latter having a fluid-filled working space coupled to 2 partial chambers (8,9) containing sliding pistons (12,13) driven by a tumble disc (16), which is rotated via the shaft. A control device (19,20) for each partial chamber has a blocking valve (21,22) connecting the partial chamber with the working space and a flow valve (23,24) connecting the working space with the partial chamber. |
