ROTARY PISTON INTERNAL COMBUSTION ENGINE Russian patent published in 2008 - IPC F02B53/08 

FIELD: mechanical engineering; internal combustion engines.

SUBSTANCE: proposed rotary piston internal combustion engine has body with combustion chamber, working chambers and different-diameter rotating disk secured in parallel on shaft. Radial slot is made in disk being rotor of compressor whose depth smoothly increases from zero to maximum value on first half of arc of disk circumference and smoothly decreases from maximum value to zero value on second half of arc of circumference of said disk. Disk, being turbine rotor, is provided with projection for contact with body and spring-loaded shutter. Combustion chamber is made in form of coaxial outer, middle and inner cylinders nested in each other. Outer cylinder is divide by plane passing through axes of shaft and cylinders into half-cylinders, first of which being rigidly secured in body, and second one, being piston, is arranged in slot of disk which serves as rotor of compressor. It is installed for displacement relative to first half-cylinder till inclined bottom of second half-cylinder adjoins base of slot of said disk. Middle cylinder and inner cylinder installed for rotation are provided with ports to take working mixture into combustion chamber and bypass ports to discharge burning working mixture. Diameter of disk being turbine rotor exceeds diameter of disk being compressor rotor. Turbine rotor disk is made in form of short cylindrical member whose projection is arranged on its inner surface. Combustion chamber is arranged inside disk being rotor of turbine.

EFFECT: increased engine power.
