Patent for more than, we can know, existing atomizer will go the structure that installing is filtered, and existing
By the way of filter screen and filter core, and existing filter screen is usually the filter screen group for including filter screen bracket and being arranged on support
Into, it is short to there is service life in it, structural strength and poor filtration effect, and handling it is inconvenient the problem of.
The content of the invention
In order to overcome the technical deficiency of the above, the present invention provides a kind of for the filtering valve seat of automobile oil nozzle and oil spout
Mouth.
The present invention provides a kind of automobile oil nozzle, and it includes setting at oil nozzle body, the oil-out of the oil nozzle body
There is valve seat, the valve seat center is provided with the through hole of insertion, annular boss is set on the outside of through hole, is set on the outside of the annular boss
Put supporting surface, oil separating plate be set above the valve seat, the oil separating plate is circumferentially with some oil ducts, the annular boss with every
Gap is provided between oiled-plate method, the oil duct is connected by gap with through hole, and the height in the gap can stop that impurity passes through.
The gap is 0.04-0.08mm.
The annular boss is integrally upwardly extended by the valve base surface and formed, and its section is trapezoidal.
Annular groove is set on the outside of the annular boss.
The inner side of the annular groove on the outside of the annular boss with seamlessly transitting.
The annular boss to the through hole is provided with extension.
The section of the through hole is in the conical surface.
The oil separating plate is arranged on the supporting surface, and is brought into close contact with the supporting surface.
The height of the supporting surface is more than the height of the annular boss.
The oil duct equi-spaced apart is distributed in the circumference of the oil separating plate.
Beneficial effects of the present invention：Gap between the annular boss and oil separating plate that are set using valve seat upper process, and protect
Demonstrate,prove the gap and be only capable of oil, and the impurity in oil can not then go over from the gap, so that the effect of filtering is served, and without increasing
Plus filter screen structure, material is saved, while easier for installation, fixation and installation without considering screen pack.

Embodiment
Embodiments of the present invention is further illustrated below in conjunction with the accompanying drawings：
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6 and Fig. 7, the present invention provides a kind of automobile oil nozzle, and it can be fuel oil
Atomizer, gas atomizer and urea atomizer；It includes being provided with oil nozzle body, the oil-out of the oil nozzle body
Valve seat 1, the center of valve seat 1 is provided with the through hole 11 of insertion, annular boss 13 is set in the outside of through hole 11, in the annular boss
13 outsides set supporting surface 12, set oil separating plate 2 in the top of valve seat 1, the oil separating plate 2 is circumferentially with some oil ducts 21,
Gap 16 is provided between the annular boss 13 and oil separating plate 2, the oil duct 21 is connected by gap with through hole, the gap
Height a only fuel feeding passes through, and oil separating plate is pressed close in the gap enough, the gap between 0.04-0.08mm so that the gap every
From the impurity in fuel, the effect of filtering can be played, and utilize annular boss and the inherent filtration effect of oil separating plate formation, energy
Screen pack or filtration need not be enough further added by, cost is greatly reduced, and the fixed form of screen pack need not be considered.
The annular boss 13 is integrally upwardly extended by the valve base surface to be formed, and its section is trapezoidal.Annular boss
13 is circumferentially disposed centered on the through hole of valve seat 1, and forms gap between oil separating plate 2, and gap annular is set, so as to ensure
Oil can enter through hole from all directions, so that sprayed at the oil outlet of atomizer, and when the sufficiently small situation in gap
Under, moreover it is possible to the atomizing effect that increase oil sprays.
In the outside of annular boss 13, annular groove 15, the inner side of the annular groove and the outside of the annular boss are set
Seamlessly transit, when the impurity in oil is filtered by the gap, these impurity will be slid to this along the cell wall seamlessly transitted
In annular groove, so as to be accumulated in annular groove, without being blocked in gap location, causing gap to be blocked influences oil spout effect, and
And the impurity being deposited in the annular groove can be cleaned after filtering valve seat taking-up, so as to improve the use of the atomizer
Life-span.
Annular groove is not provided with, then impurity may enter in valve seat, the sealing effectiveness between destruction core 3 and valve seat is led
Atomizer direct-injection is caused, so that it is bad by the bent axle top of engine to occur taking blame for others, so as to very big danger occur, that is, is caused at atomizer
In the case of a direct-injection, when unexpected igniting, it may result in engine failure.
Impurity screening is stored in the groove of the annular groove simultaneously, Filter length can be reduced, therefore declining for pressure can be reduced
Subtract, if groove, pressure can diminish, influence flow.
The annular boss to the through hole is provided with extension 14, extends to the side of through hole through extension by boss
Wall, the distance that extension oil passes through, so that passing through more steadily for oil, improves oil yield efficiency.
The section of the through hole be in the conical surface, from large to small, and preferably sealed with core, it is ensured that atomizer it is close
Seal effect.
The oil separating plate is arranged on the supporting surface, and is brought into close contact with the supporting surface, the height of the supporting surface
More than the height of the annular boss, that is, ensure that oil separating plate directly will not fit with the highest face of annular boss, so as to influence it
It is fuel-displaced, and more facilitate in processing.
The oil separating plate is circumferentially equidistant to be provided with some oil ducts, is sprayed the oil in oil pocket using circumferentially disposed oil duct, and
And crossed by oil duct after annular boss, it can be very good to realize filtering.
Embodiment is not construed as limitation of the present invention, any spiritual improvements introduced based on the present invention, all Ying Ben
Within the protection domain of invention.
