Description
Technical field
This utility model relates to technical field of automobile components, particularly relates to a kind of new type gasoline fuel injector valve rod fore-set and combines
Body.
Background technology
The gasoline engine produced now has fuel injector (except motorcycle), and fuel injector is commonly called as atomizer, briefly gasoline
The effect of the fuel injector on machine is: by liquid, quantitative fuel oil is become vaporific, then mixes with air；In electric-controlled fuel injector one
As have valve rod, spring fore-set, spool, spring, valve seat (including sealed steel ball), wherein spring fore-set and withstands spring in valve rod
One end, the spring other end then withstands spool, and electric-controlled fuel injector is externally provided with coil, and operation principle is, during coil no power, automatically controlled spray
Oil device spool withstands on sealed steel ball under the common effect of high pressure gasoline and spring, and oil circuit is obstructed, produces magnetic during coil electricity
Power, spool generation action, high pressure gasoline is by spraying after sealed steel ball.Electric-controlled fuel injector is the essence that a kind of machining accuracy is the highest
Close device, if production, installation process can be simplified on the premise of fitness for service requires, can receive preferable benefit undoubtedly.
Summary of the invention
This utility model is high in order to solve the electric-controlled fuel injector requirement on machining accuracy of prior art, produces complexity slowly
Problem, it is provided that a kind of electric-controlled fuel injector structure that simplifies, the new type gasoline fuel injector valve rod fore-set knot of reduction processing and installation difficulty
Fit.
To achieve these goals, this utility model is by the following technical solutions: a kind of new type gasoline fuel injector valve rod top
Post coalition, described gasoline ejector includes valve body, valve rod fore-set coalition, spool, spring, valve seat, described valve rod top
Post coalition is located at gasoline ejector valve body stage casing, and described valve rod fore-set coalition is cylindrical, described valve rod fore-set coalition
Inside being provided with hollow pipe, described spool is located between valve rod fore-set coalition and valve seat, described both ends of the spring respectively against
Valve rod fore-set coalition and spool.The valve rod and spring fore-set that are originally used for two parts are combined by this programme, form one
New part-valve rod fore-set coalition, valve rod fore-set coalition possesses former valve rod, the function of spring fore-set, valve rod and bullet completely
Spring fore-set needs precision-fit originally, after being integrated, decreases processing, the technique amount installed, improves productivity effect.
As preferably, described hollow pipe is provided with the oil suction chamber of different tube diameters, spring cavity, described oil suction chamber, spring
Chamber intersection is provided with the shaft shoulder, and described spring one end contacts with the shaft shoulder.A solution of this programme, is i.e. at hollow pipe
Inside arranging the shaft shoulder that can withstand spring, play the effect of original spring fore-set, the shaft shoulder is by the oil suction chamber of different tube diameters and spring
Chamber is formed, and is gasoline channel in hollow pipe.
As preferably, outside described valve rod fore-set coalition stage casing, it is provided with annular boss, described valve rod fore-set coalition
And it is provided with gap between spool.The annular boss of this programme valve rod fore-set coalition is for being connected with valve body, and valve rod fore-set combines
Gap between body and spool, for providing mobile space to spool, all serves the effect of original valve rod.
Therefore, this utility model has the advantages that (1) simplifies electric-controlled fuel injector structure；(2) reduce automatically controlled
Fuel injector processing and installation difficulty.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
In figure: 1, valve body 2, valve rod fore-set coalition 3, spool 4, spring 5, valve seat
6, oil suction chamber 7, spring cavity 8, the shaft shoulder 9, annular boss 10, gap.
Detailed description of the invention
As it is shown in figure 1, a kind of new type gasoline fuel injector valve rod fore-set coalition, gasoline ejector includes valve body 1, valve rod top
Post coalition 2, spool 3, spring 4, valve seat 5, valve rod fore-set coalition 2 is located at gasoline ejector valve body 1 stage casing, valve rod fore-set knot
Fit 2 be cylindrical, is provided with hollow pipe in valve rod fore-set coalition 2, spool 3 be located at valve rod fore-set coalition 2 and valve seat 5 it
Between, spring 4 two ends are respectively against valve rod fore-set coalition 2 and spool 3, and hollow pipe is provided with the oil suction chamber 6 of different tube diameters, spring
Chamber 7, oil suction chamber 6, spring cavity 7 intersection be provided with the shaft shoulder 8, and spring 4 one end contacts with the shaft shoulder 8, outside valve rod fore-set coalition 2 stage casing
Side is provided with annular boss 9, is provided with gap 10 between valve rod fore-set coalition 2 and spool 3.
Specific implementation process is, after valve rod fore-set coalition 2 is installed on valve body, is withstood on by spring 4 on spool 3, valve rod
The gap 10 mobile space as spool 3 it is provided with between fore-set coalition 2 and spool 3.
