ROTOR INTERNAL COMBUSTION ENGINE AND METHOD OF ITS OPERATION Russian patent published in 2006 - IPC F02B53/08 F01C1/344 

FIELD: engine engineering.

SUBSTANCE: engine comprises cylindrical working space which receives cylindrical rotor, intermediate section with the inlet and compression chambers, and end sections with the chambers for working stroke and exhaustion. The volume of the intermediate section space is equal to the volume of two end sections. The radial blades of the end sections are angled at 180° to each other and 90° to the diametrical blade of the intermediate section. According to a version, the step projection on the blade of the section for working stroke defines a space together with the recess in the rotor. The space is in communication with the working stroke chamber through a passage, which provides a force for compensating the gas pressure on the projecting section of the blade. The engine is lubricated by pumping a lubricant through the passages in the spaces of contact between the blade and the housing. Each blade is made of three plates. The lubricant is circulated over ths in a groove provided over periphery of the the intermediate plate. The lubricant is cooled in the radiator by means of a coolant, and in the absence of the coolant, the lubricant is cooled by air.

EFFECT: enhanced reliability.
