JET-CAVITATION EJECTOR TO PREPARE WATER-FUEL EMULSION Russian patent published in 2009 - IPC F02M25/00 

FIELD: engines and pumps.

SUBSTANCE: invention relates to engine production, particularly, to ICE fuel systems. Jet-cavitation ejector is designed to prepare water-fuel emulsion and to feed it into ICE fuel system and consists of the casing and active jet. The said active circular jet can move along ejector casing. The ejector comprises also the holes communicating the casing inner chamber with water feed tank, a fixed diffuser connected to the casing end face. The proposed ejector comprises additionally a membrane-type vacuum chamber arranged on the second end face of the casing and consisting of a cup, cover and membrane from elastic material, for example, rubber. The chamber cover accommodates an adjusting device consisting of a screw and coil spring. Screwed in screw acts, via the said spring, onto membrane of the adapter, its one end being connected with the membrane and its other end with the active jet pin. The vacuum chamber cover accommodates a union communicating the chamber with the engine intake manifold and a gland arranged between the vacuum chamber casing and cup. Note that the active jet inside has a through radial hole, tapered hole and groove made along the diameter and furnished with radial holes. Note here that the said tapered and radial holes communicate with that in the casing to communicate the housing chamber with the engine fuel system. Fixed diffuser is connected with the line feeding emulsion into engine.

EFFECT: automatic adjustment of water-fuel emulsion preparation and feed system.
