The operating principle of the motor is based on an internal gearbox consisting of a fixed toothed ring. with internal rollers and a gearwheel meshing with it, through which the output torque and speed are transmitted The rollers in the toothed ring reduce the load and distribute the tooth force optimally. This achieves a long service life and better efficiency even with high continuous pressure. gear wheel set with rollers is recommended for operation with low-viscosity oil and under operating conditions with frequent changes of direction of rotation The distributor valve is driven synchronously with the gear set so that the filling and emptying of the individual chambers of the engine takes place precisely - without losses. The drum valve is part of the output shaft. The cardan shaft transmits the mechanical energy from the gear set to the output shaft.
