Abstract
The utility model discloses an oil nozzle of an automotive electronic-injection fuel oil pump assembly. The oil nozzle comprises an oil nozzle body (1), the oil nozzle body (1) is provided with an oil injection passage (2) inside, and the oil injection passage (2) is communicated with an oil injection port (3). The oil nozzle is characterized in that an oil nozzle joint (4) is arranged at the oil injection port (3) and is provided with an oil injection hole (5) communicated with the oil injection port (3). The oil nozzle joint (4) is made of copper, so that the hole diameter of the oil injection port is increased, a die core is thickened, and service life of a die is improved; the oil nozzle joint (4) is a copper joint, and accuracy is easier to control during processing.
Description
Technical field
The utility model relates to a kind of vehicle electric injection fuel pump, particularly be the oil nozzle for vehicle electric injection fuel pump assembly.
Background technique
The oil nozzle of vehicle electric injection fuel pump assembly is varied in the market, its effect is also had nothing in common with each other, as plastic injection-moulded oil nozzle, nozzle diameter is in the time of < Ф 1mm, the fuse of mould is too thin, will be very easy to fracture when injection moulding, and mould is met easily generation burr of place, spout is stopped up, have a strong impact on the up-to-standard rate of die life and part.The size of nozzle diameter directly affects the effect of its siphon for electric-spraying fuel pump assembly, and its required precision is very high, and plastic injection-moulded oil nozzle precision is difficult to control.
Summary of the invention
In view of the problem that known technology exists, the technical problems to be solved in the utility model be to provide a kind of precision higher, process oil nozzle more easily.
For solving the problems of the technologies described above, the utility model takes following technological scheme to complete:
A kind of oil nozzle of vehicle electric injection fuel pump assembly, include oil nozzle body, in described oil nozzle body, be provided with fuel injection passage, described fuel injection passage and jet are connected, it is characterized in that: described jet has been nested with oil nozzle joint, described oil nozzle joint is provided with nozzle opening, and described nozzle opening and jet are connected, and the material of described oil nozzle joint adopts copper.Described oil nozzle joint is provided with barb.The aperture of described nozzle opening is φ 0.55.
The beneficial effects of the utility model are: so just can strengthen the aperture of jet, make the overstriking of mould fuse, improve the working life of oil nozzle mould, and oil nozzle joint adopts copper sleeve, add man-hour easier control accuracy and improved conforming product rate.
Brief description of the drawings
Further describe by reference to the accompanying drawings again embodiment below:
Fig. 1 is the utility model structural representation;
Fig. 2 is the enlarged view of Fig. 1.
Embodiment
Accompanying drawing has represented structure of the present utility model and embodiment, each details of embodiment is described below more by reference to the accompanying drawings, this includes oil nozzle body 1, in described oil nozzle body 1, be provided with fuel injection passage 2, described fuel injection passage 2 is connected with jet 3, described jet 3 has been nested with oil nozzle joint 4, described oil nozzle joint 4 is provided with barb, be that oil nozzle joint 4 is provided with projection, the face that this projection contacts with jet 3 for inclined-plane, from low to high, the rear portion of projection is just as a hook like this, when oil nozzle joint 4 is put into jet 3, inclined-plane along projection puts in, but be difficult to extract, effectively prevent that oil nozzle joint 4 from departing from, described oil nozzle joint 4 is provided with nozzle opening 5, described nozzle opening 5 is connected with jet 3, the material of described oil nozzle joint 4 adopts copper, copper joint is processed as car part, its precision is easily controlled, and up-to-standard rate is high, so just strengthen the aperture of jet 3, make the overstriking of mould fuse, improve the working life of oil nozzle mould.The utility model simplicity of design, but can reach very useful effect, must bring better benefit to enterprise.
Claims (3)
