Abstract A clutch and brake apparatus operable by a compressible fluid, partic- ularly pneumatically, comprising input (1) and output (2) shafts mounted in a common housing (2, 4) is desoribed, wherein a clutch flange (5) fixed to rotate with the input shaft and a clutch plate (6) are disposed in the clutch chamber (11), and the clutch plate (6) subdivides the clutch chamber (11) into two operating chambers (9, 10) adapted to be at different pressures and can be applied to the clutch flange (5) with an interposed friction lining (7, 8) or to an end face (26) of the clutch chamber (11). In this construction, there used to be the problem that only a limited torque could be transmitted because the clutch plate had to be bent out so as to make contact with the individual friction faces. For higher torques, the pressure in the operating chambers had to be increased so that the clutch plate was subjected to impermissibly high stresses. The new apparatus is to be able to operate with a large pressure difference across the clutch plate without the danger of damaging the clutch plate. For this purpose, the clutch plate is mounted to be slightly axially displaceable relatively to the output shaft in every load condition, at least one axially non-rotatable torque plate is fixed to rotate with the output shaft and the circum- ference of the clutch plate, and the torque plate is subjected to the same pressure on both sides.
