ROTARY INTERNAL COMBUSTION ENGINE

WIPO Patent Application WO2000034636

A8

The present invention pertains to rotary internal combustion engines and essentially relates to an engine including a body that comprises an inner cylindrical cavity as well as side covers. The cavity comprises a rotor-piston which is concentrically mounted therein, which comprises side surfaces, radial protrusions and radial recesses on its peripheral surface, and which forms together with the body a plurality of segmented cavities. The side surfaces of the rotor-piston abut tightly with the side covers, while the radial protrusions at the peripheral surface of the rotor-piston abut tightly with the inner cylindrical surface of the body cavity. The combustion chamber is located beyond the limits of the inner cylindrical cavity and communicates with the latter through inlet and outlet channels provided with controlled slide valves. This engine also includes discharge and supply channels as well as separation vanes which are mounted so as to be capable of radial displacement in the grooves of the body and of the inner surfaces of the side covers between the inlet and outlet channels of the combustion chambers as well as between the discharge and supply channels. The separation vanes are connected to a control mechanism, are brought into contact with the peripheral surface of the rotor-piston and define together with the radial recesses of the rotor-piston, with the inner surface of the cylindrical body and with the side covers of the body a plurality of segmented working chambers. This engine is characterised in that it further includes a second combustion chamber which is identical to the first one and is isolated therefrom. The first combustion chamber communicates with the inner cylindrical cavity of the body through a first inlet channel and a first outlet channel provided with controlled slide valves, while the second combustion chamber communicates with the inner cylindrical cavity of the body through a second inlet channel and a second outlet channel also provided with controlled slide valves. This engine has a high specific output as well as a regular torque.
