Abstract: The compressed air radial motor includes a supporting disc, supporting a plurality of fluid cells, which is pneumatically controlled by a control head disposed rotatably fixed in the motor housing and which is rotatably connected to a conical supporting disc supported on the motor shaft via the fluid cells, a diaphragm being disposed at the outer front side of the control head which, on the inner side, is under the flow pressure of the pressure medium flowing through the driving-side of the control head, and, on the other side, supports the control head against the supporting disc via a counter surface in the motor housing.
