ROTARY VANE MACHINE Russian patent published in 2004 - IPC

FIELD: mechanical engineering; internal combustion engines.

SUBSTANCE: proposed machine has cylindrical housing with three working chambers formed by three cylindrical surfaces smoothly conjugated with each other in form of three projections. Centers of cylindrical surfaces lie on vertices of equilateral triangle whose center coincides with center of rotor in contact with three projections by three spring-loaded vanes arranged at angle of 120 degrees between vanes. Each projection accommodates combustion chamber with intake and outlet flat valves rigidly mounted on rocker. Outlet flat valve is rigidly secured on short arm of rocker. Rocker is spring-loaded relative to axle and is provided with curve to open inlet valve and close outlet valve, and vice versa. Rotor is sealed on its end face surface by spring-loaded disk whose outer contour follows inner surface of housing.

EFFECT: increased efficiency in operation.
