Background technique
Oil sprayer itself is a normally close valve, is moved up and down the switching of control valve by needle.When ECU assigned the oil spout instruction, its voltage signal can make flow through coil in oil sprayer of electric current, produces magnetic field valve rod is picked up, and allows valve opening that oil plant can be sprayed from nozzle opening.The great advantage of spraying fuel feeding is exactly that the control of fuel delivery is very accurate, allows engine under any state, correct air fuel ratio can be arranged, and not only allows engine keep running smooth and easy, and its waste gas also can conform with the standard of environmental regulation.
As the oil sprayer of one of critical component of electronic fuel injection engine, the continuous injection rate of oil sprayer will directly affect the performance of motor.Existing oil sprayer is that processing and assembling is convenient, and the spiral hole of guide plate is the through hole that direct punching press forms, and when controlling oil spout, sprays outward fuel by straight spiral hole.The fuel oil that ejects due to the pod apertures of straight distribution can be concentrated and be distributed in the oil sprayer outlet end, fogging degree is still lower, fuel oil under high pressure easily occuring insufficient, can not satisfy fuel oil especially recyclable fuel such as ethanol, the spraying requirement of vegetable seed wet goods under the different operating condition.
So well-known, bio-fuel-oil is typical case's " green energy resource ", and the development bio-fuel-oil advances energy substitution to sustainable economic development, alleviates external pressure, controls urban atmospheric pollution and has important strategic importance.
The model utility content
In order to overcome deficiency and the defective in background technique, the utility model provides a kind of electric-jet type umbrella for cars shape spiral ethanol injector assembly, mainly solves existing injector assembly and exists in use fogging degree low, and fuel oil is than low problem.
the technical solution of the utility model is: the spiral ethanol injector assembly of a kind of electric-jet type umbrella for cars shape, comprise oil inlet pipe, valve rod, valve seat, block and oil outlet tube, the side of oil inlet pipe is provided with filler opening, described valve rod is located in oil inlet pipe, it is interior and corresponding with valve rod that described valve seat sets out oil pipe, described block is located at the opposite side of the corresponding valve rod of valve seat, the first through hole is established in described valve seat block center, described valve seat center is provided with second through hole corresponding with described the first through hole, be provided with guide plate between described valve seat and block, it is characterized in that: described guide plate is provided with a plurality of along the circumferential spiral hole that distributes in guide plate center.
The corresponding guide plate of described spiral hole center ring-type evenly distributes, and along guide plate center single direction rotation setting.
Plane, the corresponding described guide plate place of described spiral hole is the helix angle of 15 ~ 75 °.
Described guide plate upper surface center is provided with locating column, and described upper locating column coordinates with the first through hole is spacing.
Described guide plate lower surface center is provided with lower locating column, and described lower locating column coordinates with the second through hole is spacing.
The beneficial effects of the utility model: owing to taking such scheme, the spiral ethanol injector assembly of electric-jet type umbrella for cars shape of the present utility model, high pressure fuel is by the flow through spiral hole of horn-like distribution of valve seat place, after circumferential diffusion, effectively enlarged the diffusion space of fuel oil, has fogging degree good, the sufficient characteristics of fuel oil.
Description of drawings
Fig. 1 is the partial sectional view that the utility model is implemented.
Fig. 2 is the structural representation of guide plate in Fig. 1.
Fig. 3 is the plan view of guide plate in Fig. 1.
In figure, oil inlet pipe 1, valve rod 2, oil outlet tube 3, valve seat 4, the first through holes 41, guide plate 5, upper locating column 51, lower locating column 52, spiral hole 53, block 6, the second through holes 61.
Embodiment
The below is described further embodiment of the present utility model for accompanying drawing:
by shown in Figure 1, the spiral ethanol injector assembly of a kind of electric-jet type umbrella for cars shape, comprise oil inlet pipe 1, valve rod 2, valve seat 4, block 6 and oil outlet tube 3, the side of oil inlet pipe 1 is provided with filler opening, described valve rod 2 is located in oil inlet pipe 1, it is interior and corresponding with valve rod 2 that described valve seat 4 sets out oil pipe 3, described block 6 is located at the opposite side of the corresponding valve rod 2 of valve seat 4, the first through hole 41 is established in described valve seat 4 block 6 centers, described valve seat 4 centers are provided with second through hole 61 corresponding with described the first through hole 41, be provided with guide plate 5 between described valve seat 4 and block 6, described guide plate 5 is provided with a plurality of along the circumferential spiral hole 53 that distributes in guide plate 5 centers.The oily device of disputing is normally close valve, and high pressure oil is entered in valve rod 2 cavity volumes by the place, axle center of oil inlet pipe 1, and do not open for oil sprayer this moment, and high pressure oil is stored in holding cavity.When ECU assigned the oil spout instruction, its voltage signal can make flow through coil in oil sprayer of electric current, produces magnetic field valve rod 2 is picked up, and allows valve opening that oil plant can be sprayed from nozzle opening, formed vaporificly, was convenient to abundant burning.High pressure fuel flows to guide plate by the valve seat place, via the spiral hole of horn-like distribution on guide plate, after carrying out circumferential diffusion, has effectively enlarged the diffusion space of fuel oil, has a fogging degree good, the sufficient characteristics of fuel oil.
