VERSATILE WORKING EJECTOR CHAMBER (VERSIONS) Russian patent published in 2018 - IPC F04F5/44 

FIELD: engines and pumps.

SUBSTANCE: ejector chamber comprises a toroidal vessel designed to form outside the vessel an axisymmetric flow of active fluid supplied to the inner volume of the vessel by a feeding device containing feed pipe unions with profiled active nozzles, each of which creates a jet of active medium, which vector of speed is directed tangentially to the inner circuit of vessel section by meridian plane, the toroidal vessel has a circular nozzle created by cutting a portion of the toroidal vessel inner volume with a plane perpendicular to the vessel axis. Or the toroidal vessel has a circular nozzle created by cutting a portion of the toroidal vessel inner volume by the inner surface of a right circular cone coaxial to the inner surface of the toroidal vessel. Or toroidal vessel has a circular nozzle created by cutting a portion of the toroidal vessel inner volume by the inner surface of the right circular cylinder coaxial to the inner surface of the toroidal vessel.

EFFECT: expanded field of ejectors application.
