Abstract (en)
[origin: EP0391866A1] The pressure-driven motor has a main rotor (1) with pistons and connecting rods (3,4) working in one or more rings of cylinder. The protruding free ends of the rods pivot on an auxiliary rotor (6) turning on an axis eccentric to that of the main one. The rotors are coupled together, and air or fluid is delivered to the cylinders by a distributor. The main rotor is fixed to a driving shaft (2). The rotors are coupled by components giving instantaneous angular velocity and driving torque of the auxiliary one equal to those of the main one.
