Abstract
The invention relates to the technical field of engine parts and particularly relates to a gasoline spraying nozzle of a gasoline engine. The gasoline spraying nozzle comprises a valve body, wherein a cylindrical valve cavity is formed in the valve body, a cylindrical metal needle valve body is arranged in the valve cavity, the diameter of a section of the metal needle valve body is smaller than that of a section of the valve cavity, the bottom end of the metal needle valve body abuts to the bottom of the valve cavity, an electromagnet is arranged at the upper end of the valve body, a lifting gap is reserved between the electromagnet and the metal needle valve body, a gasoline spraying hole communicated with the valve cavity is formed in the lower end of the valve body, and a gasoline injection hole communicated with the valve cavity is formed in the side wall of the valve body. The gasoline spraying nozzle of the gasoline engine has the advantages that during gasoline spraying, the electromagnet is electrically conductive and adsorbs the metal needle valve body, the gasoline spraying hole is communicated with the valve cavity, and gasoline injected from the gasoline injection hole is sprayed from the gasoline spraying hole; after gasoline spraying, under the action of gravity, the lower end of the metal needle valve body abuts to the bottom of the valve cavity to seal the gasoline spraying hole, so that waste of fuel oil due to the fact that residual gasoline in the valve body flows out of the gasoline spraying hole is avoided.
Description
Technical field
The present invention relates to engine component technical field, relate in particular to a kind of petrol engine oil nozzle.
Background technique
Oil nozzle is the oil nozzle of one of critical component of electronic fuel injection engine, and its work quality is by the serious performance that affects motor.Existing oil nozzle is generally a simple valve body structure, and one end of valve body is provided with pouring orifice, and the other end is provided with jet, after oil spout, and meeting nubbin fluid in valve body, these have also and can flow out from jet, have caused also and must waste.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind of can avoid oil spout later the fluid in valve body flow out the petrol engine oil nozzle of waste.
The technological scheme that the present invention solves the problems of the technologies described above is as follows: a kind of petrol engine oil nozzle, comprise valve body, in described valve body, be provided with columniform valve pocket, in described valve pocket, be provided with the metal needle valve body that columniform diameter of section is less than described valve pocket diameter of section, the bottom butt of the bottom of described metal needle valve body and described valve pocket, the upper end of described valve body is provided with electromagnet, between described electromagnet and described metal needle valve body, be provided with and promote gap, the lower end of described valve body is provided with the nozzle opening being communicated with described valve pocket, the sidewall of described valve body is provided with the oil hole being communicated with described valve pocket.
On the basis of technique scheme, the present invention can also do following improvement.
Further, one end that described oil hole connects described valve pocket is provided with filtering cavity, in described filtering cavity, is provided with filtrating equipment.
Further, described filtrating equipment is filter screen, and the aperture of described filter screen is less than the aperture of described nozzle opening.
Further, the bottom of described valve pocket is taper, and the bottom of described metal needle valve body is taper.
Further, the quantity of described nozzle opening is more than three or three.
The invention has the beneficial effects as follows: when oil spout, electromagnet conduction, adsorbing metal needle-valve body, nozzle opening and valve pocket conducting, the gasoline injecting from oil hole is sent forth from nozzle opening, after oil spout, metal needle valve body is under the effect of gravity, the bottom of lower end butt valve pocket, seals nozzle opening, avoids gasoline remaining in valve body from oil nozzle, to flow out the waste that causes fuel oil.Arranging of filtrating equipment can be filtered the gasoline entering in valve pocket, avoids gasoline to contain impurity nozzle opening is resulted in blockage.The bottom of metal needle valve body, the bottom of valve pocket are taper, can facilitate metal needle valve body to carry out shutoff to nozzle opening.After more than three or three nozzle openings can make gasoline spraying shed, evenly, increase the area of contact of gasoline and air.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of petrol engine oil nozzle of the present invention;
In accompanying drawing, the list of parts of each label representative is as follows:
1, valve body, 2, valve pocket, 3, metal needle valve body, 4, electromagnet, 5, promote gap, 6, nozzle opening, 7, oil hole, 8, filtering cavity, 9, filtrating equipment.
Embodiment
Below in conjunction with accompanying drawing, principle of the present invention and feature are described, example, only for explaining the present invention, is not intended to limit scope of the present invention.
As shown in Figure 1, the present invention includes valve body 1, in described valve body 1, be provided with columniform valve pocket 2, in described valve pocket 2, be provided with the metal needle valve body 3 that columniform diameter of section is less than described valve pocket 2 interior diameter of sections, the bottom butt of the bottom of described metal needle valve body 3 and described valve pocket 2, the upper end of described valve body 1 is provided with electromagnet 4, between described electromagnet 4 and described metal needle valve body 3, be provided with and promote gap 5, the lower end of described valve body 1 is provided with the nozzle opening 6 being communicated with described valve pocket 2, and the sidewall of described valve body 1 is provided with the oil hole 7 being communicated with described valve pocket 2.
Preferred technological scheme is: one end that described oil hole 7 connects described valve pocket 2 is provided with filtering cavity 8, in described filtering cavity 8, be provided with filtrating equipment 9, described filtrating equipment 9 is filter screen, the aperture of described filter screen is less than the aperture of described nozzle opening 6, the bottom of described valve pocket 2 is taper, the bottom of described metal needle valve body 3 is taper, and the quantity of described nozzle opening 6 is more than three or three.
The invention has the beneficial effects as follows: when oil spout, electromagnet 4 conductions, adsorbing metal needle-valve body 3, nozzle opening 6 and valve pocket 2 conductings, the gasoline injecting from oil hole 7 is sent forth from nozzle opening 6, after oil spout, metal needle valve body 3 is under the effect of gravity, the bottom of lower end butt valve pocket 2, seals nozzle opening 6, avoids the gasoline of valve body 1 interior remnants from oil nozzle, to flow out the waste that causes fuel oil.Arranging of filtrating equipment 9 can be filtered the gasoline entering in valve pocket 2, avoids gasoline to contain impurity nozzle opening 6 is resulted in blockage.The bottom of the bottom of metal needle valve body 3, valve pocket 2 is taper, can facilitate 3 pairs of nozzle openings of metal needle valve body 6 to carry out shutoff.After more than three or three nozzle openings 6 can make gasoline spraying shed, evenly, increase the area of contact of gasoline and air
