INTERNAL COMBUSTION ROTARY ENGINE Russian patent published in 2006 - IPC F01C1/344 F02B53/00 

FIELD: mechanical engineering.

SUBSTANCE: invention can be used as power plant in different machines, and as internal combustion engines of vehicles. internal combustion rotary engine has fixed body with grooves, rotor rigidly fitted on shaft and 2 n pairs of blades in its body. Each pair of blades is two parallel extending plates. Engine contains also combustion chambers formed between plates of each pair of blades and extending devices. Plates are made inform of working and auxiliary ones, extending successively and consisting of two parts of different thickness. Toothed racks and pushers for engagement with extending device are made on parts pf plates of larger thickness moving in guide rotor. Extending device for each pair of blades is rack-cam-crank-connecting rod mechanism including slider with toothed rack coming into engagement with gear-cam shaft on which two incomplete toothed wheels are blind-fitted at both sides on central gear, displaced relative to each other and provided with accelerating and brake cams. Cavities forming combustion chambers with plates are made on rim surface of rotor between plates of each pair of blades. Profile of grooves in body in cross section is parts of two unipolar n-period antiphase sine curves displaced through angle corresponding to distance between blades brought into circle into at n=1,2,3. . .

EFFECT: compact design, simple, reliable engine of high specific power output.
