Abstract
The invention relates to the technical field of automotive engine connection cavity parts and particularly relates to a gasoline spraying nozzle. The gasoline spraying nozzle comprises a valve body, a valve cavity is formed in the valve body, a gasoline inlet is formed in the valve body, a gasoline valve is fixed at one end of the valve body, one end of the gasoline valve is arranged in the valve cavity, a gasoline cavity and a communication cavity are formed in the gasoline valve, the communication cavity is communicated with the valve cavity and the gasoline valve cavity, a blocking bead is arranged in the gasoline valve cavity, a gasoline spraying hole communicated with the outside is formed in a cavity wall of the gasoline valve cavity, an end hole, connected with one end of the valve cavity, of the communication cavity is provided with a blocking plate which is connected with the blocking bead through a spring, the spring is arranged in the communication cavity, and a through hole is formed in the blocking plate. When gasoline needs spraying, a gasoline liquid enters the valve cavity through the gasoline inlet followed by entering a connection cavity through the through hole; under the action of gasoline pressure, the blocking bead is separated from the inner wall of the gasoline valve cavity, and the gasoline liquid enters the gasoline valve cavity and is sprayed from the gasoline spraying hole; after gasoline spraying is stopped, the blocking bead tightly abuts to the inner wall of the gasoline valve cavity under the action of the spring to block the gasoline liquid in the valve body, so that waste of gasoline 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 part of automobile engine technical field, relate in particular to a kind of 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 is to provide a kind of oil nozzle, can avoid oil spout later the fluid in valve body flow out waste.
The technological scheme that the present invention solves the problems of the technologies described above is as follows: a kind of oil nozzle, comprise valve body, in described valve body, be provided with valve pocket, described valve body is provided with the filler opening that is communicated with described valve pocket, one end of described valve body is fixed with fuel tap, one end of described fuel tap is arranged in described valve pocket, in described fuel tap, be provided with fuel tap chamber and columniform communicated cavity, described communicated cavity is communicated with described valve pocket and described fuel tap chamber, described fuel tap is provided with spherical block bead in chamber, the chamber wall in described fuel tap chamber is provided with the nozzle opening being communicated with outside, the port that described communicated cavity connects one end of described valve pocket is provided with baffle plate, described baffle plate connects described block bead by spring, the diameter of described block bead is greater than the diameter in described communicated cavity cross section, described spring is located in described communicated cavity, described baffle plate is provided with through hole.
On the basis of technique scheme, the present invention can also do following improvement.
Further, in described valve pocket, be provided with filtrating equipment.
Further, described filtrating equipment is arranged on described filler opening place.
Further, the quantity of described nozzle opening is more than three or three, and described nozzle opening is evenly arranged on the chamber wall in described fuel tap chamber.
Further, the pore diameter range of described nozzle opening is 0.15mm-0.4mm.
The invention has the beneficial effects as follows: while needing oil spout, fluid is from filler opening enters valve pocket, enter in connection chamber from through hole, under the effect of oil pressure, block bead separates with the inwall in fuel tap chamber again, fluid enters in fuel tap chamber, from nozzle opening ejection, stop after oil spout, block bead is connected to tightly the inwall in fuel tap chamber under the effect of spring, fluid in valve body is formed and stopped, avoid fluid remaining in valve body to flow out waste from nozzle opening.Arranging of filtrating equipment can be filtered entering having also in valve body, avoids impurity to result in blockage to nozzle opening.Arranging of more than three or three nozzle opening can form even oil spout.
