The invention relates to positive–displacement pneumatic machines, in particular to combustion engine (CE). An engine has a body with main cylindrical cavity in which rotary piston is concentrically installed, this has radial lugs and radial depressions on peripheral surface, those form with inner walls of the body segment cavities, at least two combustion chambers placed symmetrically out of boundaries of main cylindrical cavity. Each combustion chamber is equipped with pair of channels as inlet channel and discharge channel, by means of those the combustion chamber is connected to main cylindrical cavity. Window of discharge channel to main cylindrical cavity of each pair of channels is displaced with respect to window of inlet channel of that pair to main cylindrical cavity in direction of rotation of the rotary piston and between those windows in radial positions movable separation paddles are installed, those adjoin peripheral surface of the rotary piston. Discharge and suction channels are in pairs and symmetrically placed between pairs of inlet and discharge channels and window to main cylindrical cavity of suction channel in each pair of suction and discharge channels is displaced with respect to window of discharge channel of that pair to main cylindrical cavity in direction of rotation of the rotary piston. Between those windows in radial positions movable separation paddles are installed, those adjoin peripheral surface of the rotary piston. |
