INTERNAL COMBUSTION TURBOROTOR ENGINE Russian patent published in 2005 - IPC

FIELD: mechanical engineering; internal combustion engines.

SUBSTANCE: proposed engine contains housing with inner compression and expansion space communicating through combustion chambers uniformly spaced over circumference. Rotor and gates form variable-capacity chambers. And gates are arranged in pairs near every combustion chamber, one in compression space, and the other, in expansion space. According to invention, ring channels for delivering lubricating liquid are made in side walls of compression and extension spaces in contact with end face surfaces of rotor disks. Said channels are open to side of spaces. Sealing rings are installed on planes of contact of end face surfaces of rotor disks and side walls of compression and expansion spaces in inner part of engine. Drain grooves are made in end face surfaces of disks of rotor and gates.

EFFECT: simplified design, increased reliability of sealing element in operation, improved efficiency of engine.
