<p>The device (2) has an actuating body limited by functional parts (14, 16), so that the actuating body is loaded against one of the functional parts in a circumferential direction during rotation of the other functional part and is even displaced in an axial direction. Axial distance between the two functional parts is enlarged, so that pressing force on a tool (8) is increased. The actuating body comprises a flexibly deformable material i.e. polymer. The actuating body comprises an element filled with a hydraulic fluid.</p> |
