Abstract
A novel fuel spray nozzle mainly solves the problems that engine performance is affected due to the fact that sealing is not good, and fuel leakage is easy. The novel fuel spray nozzle is characterized in that a valve cover is arranged under a valve seat, a fuel outlet is formed in the center of the valve cover, and the valve seat and the valve cover are matched in an end face sealing mode. The novel fuel spray nozzle has the advantages that the valve cover and the valve seat are in end face sealing, sealing performance is good, and fuel leakage is reduced.
Description
Technical field
The utility model relates to a kind of field of mechanical technique, is specifically related to a kind of fuel spray nozzle.
Background technique
Oil nozzle itself is a normally close valve, has needle to move up and down the switching of control valve.When ECU assigns the oil spout instruction, the coil that its voltage signal can make electric current flow through in oil nozzle, produce magnetic field valve rod picked up, and allows valve opening make well oil plant spray 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.
Usually, the oil spout exit seal seals by ball sealer, although Spherical Seals is flexible, its sealing is not good, easily leakage of oil, thus affect the performance of motor.
The model utility content
In order to overcome the deficiency of background technique, the utility model provides a kind of fuel spray nozzle, solves existing oil nozzle sealing not good, easily the problem of leakage of oil.
The technological scheme that the utility model adopts: a kind of fuel spray nozzle, comprise shell, and suit oil inlet pipe, valve rod, valve seat in the enclosure, described valve rod, valve seat are sleeved in oil inlet pipe, between described valve rod and valve seat, by elastic element, be connected, described valve seat below is provided with valve gap, and described valve gap center is provided with oil outlet, and described valve seat coordinates by end face seal with valve gap.
The outer ring sleeve of described oil inlet pipe is equipped with coil carrier, and described coil carrier is around with coil, and described coil outer ring sleeve has coils protective hood.
The below of described valve gap is provided with spray bar.
Described elastic element is spring.
The beneficial effects of the utility model are: adopt above scheme, between valve gap and valve seat, by end face seal, its good seal performance, reduce the leakage of oil situation.

Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
As shown in Figure 1, Figure 2 and Figure 3, a kind of fuel spray nozzle, comprise shell 1, and be sleeved on oil inlet pipe 2, valve rod 3, the valve seat 4 in shell 1, described valve rod 3, valve seat 4 are sleeved in oil inlet pipe 2, between described valve rod 3 and valve seat 4, by elastic element 5, are connected, and described valve seat 4 belows are provided with valve gap 6, described valve gap 6 centers are provided with 3 oil outlets 61, and described valve seat 4 coordinates by end face seal with valve gap 6.Oil nozzle is normal closed gate, and high pressure oil is entered by oil inlet pipe, because valve seat and valve gap end face fit tightly sealing, high pressure oil is stored in molten chamber, when ECU assigns the oil spout instruction, and the electric current flowing through coil, produce magnetic field, mention valve seat, oil content Tong Guo not sprayed by 3 nozzle openings, form vaporific, be convenient to burning, directly utilize the end face of valve seat and valve gap to be sealed, sealing effect is better, is not prone to the leakage of oil situation.
The outer ring sleeve of described oil inlet pipe 2 is equipped with coil carrier 7, and described coil carrier 7 is around with coil, and described coil outer ring sleeve has coils protective hood 8.Described coil periphery is set up safety cover one, when the electric current flowing through coil, can play certain protective action, avoids occurring the phenomenons such as electric leakage.
The below of described valve gap 6 is provided with spray bar 9.Described spray bar 9 is relative with nozzle opening 61 should be 3, and described oil is first by the oil outlet ejection, then through the spray bar ejection, its oil spout scope more, better effects if.
