Abstract

The fuel injection nozzle is for fitting to an I.C. engine. It has an oblong housing (10) containing a chamber (15) open at one end and ending in a bore (16) at the other leading to an outlet (14). A sliding valve (18) works against a seat (17) in the bore, and an inlet union for fuel (13) leads into the chamber, which contains a cylindrical solenoid armature (23) coupled to the valve. A cover for the open chamber and accommodates a solenoid core (21) extending inside the armature, and which when energised lifts the valve off its seat. Fuel flowing through the chamber cools the solenoid windings.

Изобретение относитс  к области двигателестроени  .The invention relates to the field of engine building.

Известна форсунка дл  двигател  внутреннего сгорЬни , содержаща  корпус с каналом подвода топлива, закреплённый на корпусе распылитель с иглой, нагруженной пружиной, и размещенный в топливном канале корпуса электромагнитный привод со статором, имеющим электрическую обмотку, и  корем l .A known nozzle for an internal combustion engine, comprising a housing with a fuel supply channel, an atomizer mounted on the housing with a spring-loaded needle, and an electromagnetic drive with a stator having an electric winding and a core l located in the fuel channel of the housing.

Недостатком этой форсунки  вл ет-. с  повышенна  теплонапр женность.The disadvantage of this nozzle is em-. with increased heat stress.

Целью насто щего изобретени   в- л етс  повышение эффективности охлаждени .The purpose of the present invention is to increase the cooling efficiency.

Указанна  цель достигаетс  тем, что на внутренней поверхности  кор  и на наружной поверхности статора выполнены спиральные ребра дл  образовани  топливного канала, а электрическа  обмотка размещена между спиральными ребрами статора.This goal is achieved by the fact that spiral ribs are formed on the inner surface of the core and on the outer surface of the stator to form the fuel channel, and the electrical winding is placed between the spiral edges of the stator.

На чертеже представлена конструктивна  схема форсунки.The drawing shows a constructive scheme of the nozzle.

Форсунка содержит корпус 1 с каналом 2 подвода топлива, закрепленный на корпусе распылитель 3 с иглой 4, нагруженной пружиной 5. В канале 2 размещен электромагнитный привод со статором 6, имеющим электрическую обмотку If и  корем 8. На внутренней поверхности  кор  8 и на наружной поверхности статора 6 вы5 полнеНы соответственно спиральные ребра 9 и 10. Электрическа  обмотка 7 размещена между спиральными ребрами 10 статора 6. The nozzle includes a housing 1 with a channel 2 for supplying fuel, mounted on the housing of a sprayer 3 with a needle 4 loaded with a spring 5. In channel 2 there is an electromagnetic drive with a stator 6 having an electric winding If and a bark 8. On the inner surface of the core 8 and on the outer surface the stator 6 is fully filled, respectively, spiral ribs 9 and 10. An electric winding 7 is placed between the spiral edges 10 of the stator 6.

Якорь 8 соединен с иглой 4 и снабжен фиксатором 11 от проворачивани  вокруг своей оси.The anchor 8 is connected to the needle 4 and is provided with a retainer 11 from turning around its axis.

Работа форсунки осуществл етс  следующим образом.The operation of the nozzle is carried out as follows.

При обесточенной электрической мотке 7 пружина 5 прижимает иглу 4 к седлу распылител  3, подачи топлива не происходит. В момент подключени  электрической обмотки 7 к источнику тока  корь 8 под действиемWhen de-energized electric coil 7, the spring 5 presses the needle 4 to the seat of the sprayer 3, the fuel supply does not occur. At the time of connection of the electric winding 7 to the current source measles 8 under the action of

20 электромагнитных сил перемещаетс  относительно статора 6, сжимает пружину 5 и поднимает иглу 4 от седла распылител  3. Происходит подача топлива форсункой. Топливо, проход The 20 electromagnetic forces move relative to the stator 6, compresses the spring 5 and lifts the needle 4 from the seat of the sprayer 3. There is a fuel supply by the nozzle. Fuel pass

25 через электромагнитный привод, омывает спиральные ребра  кор  8 и статора 6 и охлаждает электрическую обмотку 7.25 through an electromagnetic drive, washes the spiral ribs of the core 8 and the stator 6 and cools the electric winding 7.
