ELECTRICALLY CONTROLLED ATOMISER Russian patent published in 2015 - IPC F02M51/06 F02M47/02 

FIELD: engines and pumps.

SUBSTANCE: claimed nozzle (1) comprises body (2) with duel feed channel, drain channel (21) and fluid control chamber (19) connected with fuel feed channel (2) via jet (18) and with drain channel (21) via control valve (22), spring-loaded pusher (24) coupled with electromagnet armature (25), sprayer (4) with seat (5) and spraying orifices (6), and needle (8) interacting with sprayer (4) seat (5). In compliance with this invention, body (1) has extra high-pressure channel (3) connecting fluid control chamber (19) with needle (8) and accommodating pre-compressed elastically strained rod (12). Said elastically strained rod (12) is fitted in braiding (13) composed of helical spring with closed coils, bottom end being composed of compression spring. Extra channel (3) has lengthwise ledged to retain said rod (12) against flexure. Every fuel feed channel (2) communicates via jet (18) with fluid control chamber (19) communicated in its turn via control valve (22) with drain channel (42) and, simultaneously, via inclined channel (10) in sprayer (4) with separate bore (9) accommodating the needle (8).

EFFECT: simplified design, fuel saving.
