Abstract (en)
[origin: WO2007079766A1] Disclosed is a rotary piston engine comprising a rotor which is rotatably mounted in a housing and in which several pistons can be moved in a radial direction between an outer and an inner dead center. Each piston is provided with a piston rod which sits on a transversal shaft that is fastened to a sliding piece at each end, said sliding piece being movable within radial grooves in the rotor, on both sides of the piston. The external side of the sliding pieces which faces away from the piston is fitted with a pin that is accommodated in a star-shaped continuous guiding groove which is fixed to the housing. The guiding groove extends around an axis of rotation of the rotor and causes the pistons to move in a radial direction between the inner and outer dead centers.
