Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe.
As Fig. 1 is to the atomizer of the of the present utility model this band flow-guiding structure shown in 7, including valve body 100, outer needle
200.Described valve body 100 is provided with pressure chamber 110, fuel feed hole 120 and multiple first nozzle opening 130.Described outer needle 200 can move
It is arranged in described pressure chamber 110 dynamicly.Described outer needle 200 has the first conical seal 210, this first conical seal
210 are pressed on described first nozzle opening 130.Atomizer can also have inner valve needle 300, and valve body 100 can also have the second spray
Oilhole 140.Second nozzle opening 140 can use the inner valve needle 300 different from outer needle to seal, and concrete scheme applicant is in other Shens
Case please be proposed.In addition in order to clearly show that the structure of needle in Fig. 1, flow-guiding structure is eliminated.
Described pressure chamber 110 includes oil storage tank 111 and flowline 112, and the medial wall of this flowline 112 has spiral helicine
Guiding gutter 113.Formed vaporific after the ejection of spiral helicine guiding gutter 113 beneficially diesel oil, it is ensured that diesel oil is fully contacted compressed air,
Improve efficiency of combustion.Described outer needle 200 is provided with spiral helicine water conservancy diversion rib 220.The rotation direction of water conservancy diversion rib 220 and guiding gutter 113 phase
Instead, the irregular disturbance of diesel oil in this structure is conducive to pressure chamber 110, it is simple to air-fuel mixture.Described valve body 100 has tapered portion
114, this first nozzle opening 130 is positioned in described tapered portion 114, and described guiding gutter 113 includes a contraction section 115, at least one
Described first nozzle opening 130 through this contraction section 115.Diesel oil is introduced directly in part nozzle opening by guiding gutter 113, at this
Diesel oil flow velocity and the flow direction are inconsistent with other positions, are conducive to the formation of turbulent flow, improve efficiency of combustion further.
It is also preferred that the left this outer needle 200 has sliding eye 230, described inner valve needle 300 is positioned at this sliding eye 230.In described
