KARPHIDOV ROTOR ENGINE Russian patent published in 2008 - IPC F02B53/08 F02B11/00 F01C3/00 

FIELD: engines and pumps.

SUBSTANCE: invention relates to rotor engines, compressors, vacuum pumps and hydraulic machines. The rotor engine incorporates a housing accommodating a rotor with the shaft furnished with air, fuel and oil channels. The shaft spherical surface features pressure sites with air and fuel openings matching those made in a spherical bearing communicating with the combustion chambers heated to a temperature exceeding that of fuel ignition. The said chambers are arranged in a disk rigidly fitted on the rotor shaft. The rotor supports cones traveling thereon with cones incorporating air and fuel inlets. The sphere and spherical bearing abut on the cones inner and outer circumferences. The blades abut on the cones end faces and are hinged to the disk. The blades outer and inner circumferences mate the sphere and spherical bearing halves. Every half of the said spherical bearing is attached on to the disk half inner circumference. The disk is arranged across the lines of abutment on the cones to form working spaces. Exhaust gas outlets are arranged in the sphere between its end faces and the disk at the end of the expansion space at the distance from abutment line exceeding 180 degrees of the rotor turn. The cones abutting on the blades are furnished with the cuts in the area they are aligned with the exhaust outlets.

EFFECT: higher efficiency, simpler design.
