Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe wholely.
Such as this helical form atomizer of Fig. 1 to the present invention shown in 7, including valve body 100, outer needle 200.Described valve body
100 are provided with pressure chamber 110, fuel feed hole 120 and multiple first nozzle opening 130.Described outer needle 200 is movably disposed at institute
State in pressure chamber 110.Described outer needle 200 has the first conical seal 210, and this first conical seal 210 is pressed in described
On first nozzle opening 130.Atomizer can also have inner valve needle 300, and valve body 100 can also have the second nozzle opening 140.Second
Nozzle opening 140 can use the inner valve needle 300 different from outer needle to seal, and concrete scheme applicant proposes in other application cases.
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
