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.

Abstract: Fluid cell arrangement for compressed air radial motors, comprising a plurality of fluid cells arranged rosette-shaped to one another in a pressureless state and approximately plane for the alternate inflation of fluid cells, which are provided with air connector means and which are formed by welding two leaves of film or foil made of synthetic resin along the peripheries of the cells. In this connection, an endless elastic rubber cord or ring inserted between the two film leaves extends along the peripheries of the cells and is disposed in radial arrangement near the center of rotation, the two film leaves made of synthetic resin being disposed on both sides of the ring and completely enclosing the latter are welded together.
