A revolving blade drive actuated by a pressurized fluid has a housing in which a revolving blade is mounted. The revolution of the revolving blade is limited by a fixed stop arranged in the cylindrical inner space of the housing. The stop forms with the revolving blade two separate variable-volume working chambers inside the housing associated each to pressure medium inlets and outlets. In order to improve such a drive, so that it may be more resistant to stress and easier to mount on, in particular in handling and automating technology, the revolving blade (4) is directly rotationally fixed by its two ends to a flange (6, 7), and each flange (6, 7) is rotatively mounted in the housing (2). |
