Boots 4 close on one end and are provided with valve pocket switch side 5.4, are slidably fitted with valve element 11 in valve pocket axis hole 5.2, the valve below valve element 11
Spring base 2 is fixed with set axis hole 5.2, spring 1 is installed on spring base 2, upper end and the valve element 11 of spring 1 offset,
Metering orifice 11.1 is offered on the side wall of valve element 11.
Filter screen 7 is provided with the valve pocket 5 of the position of valve pocket inlet hole 5.1.
Diameter of the outside diameter of the valve element 11 more than pole shoe axis hole 4.1.
Balance pipe 11.2 is offered on the upper surface of valve element 11, the axis of balance pipe 11.2 is with the axis of valve element 11 in flat
Row is set.
Guide pin bushing 15 is provided with the housing 3, armature 12 is installed in guide pin bushing 15, the cylindrical and guide pin bushing 15 of armature 12
There is gap between inner circle.
The upper end of the pole shoe 4 is wedge structure.
The present invention carries out reliable electric and is connected by plug-in unit 6 and external control circuit；Valve pocket 5 is filled with pole shoe 4 using interference
Match somebody with somebody, and valve pocket 5 uses through-hole structure, simplifies the processing technology of valve pocket 5, improves its machining accuracy, particularly valve pocket axis hole
5.2 grinding precisions；Valve pocket 5 cancels the former requirement matched one by one with pole shoe 4, convenient to overhaul and change；
Valve element 11 and the match grinding of valve pocket axis hole 5.2, enable valve element 11 interior slidably in valve pocket axis hole 5.2；Valve element 11 is drum
Shape structure, drum side wall is provided with metering orifice 11.1；Valve pocket axis hole 5.2 is provided with annular oil storage tank 5.3, annular oil storage tank 5.3 and pole
Boots 5 close on one end and are provided with valve pocket switch side 5.4, are fuel-flow control side；Original state, the lower end of metering orifice 11.1 of valve element 11 is slightly higher
Side 5.4 is switched in valve pocket, there is certain misalignment margin；
Sealing ring being offered in the lower surface of pole shoe 4 and annular groove being installed, it is O-shaped to be provided with colored dentation in sealing ring installation annular groove
Sealing ring 20；Flower dentation O-ring seal 20 includes O-ring seal body 20.1 and toothed projections 20.2, and O-ring seal body
Thickness of 20.1 thickness more than toothed projections 20.2；O-ring seal body 20.1 offsets with pole shoe 4, and toothed projections 20.2 will
The upper end of filter screen 7 is pressed on described valve pocket 5.
Valve pocket 5 is connected with filter screen 7, and unqualified impurity particle causes the clamping stagnation of valve element 11 into valve pocket inner chamber in stopping fuel oil,
Cause oil pump oil mass out of control；The lower surface of pole shoe 4 is equipped with flower dentation O-ring seal 20, and its toothed projections 20.2 is compressed by pole shoe 4
On valve pocket 5, the sealing reliability of colored dentation O-ring seal 20 is improve；The press-fitting of spring base 2 loads the lower end of valve pocket 5, passes through
Regulation precompressed depth, controls flow valve starting current size.
Operation principle of the invention is as follows：
Valve element 11 is acted on by the thrust of armature shaft 9 produces slip in valve pocket 5.During original state, the metering orifice of the side wall of valve element 11
11.1 lower surfaces higher than the endoporus of valve pocket 5 valve pocket switch side 5.4, metering orifice 11.1 be in it is complete cover state, fuel oil by when be
Close flow.Spring 1 is against in the bottom hole of valve element 11 and produces and the rightabout active force of thrust of armature shaft 9, the starting of valve element 11
The pretightning force effect produced by the precompressed depth of spring base 2 during state.When control electric current is smaller, the thrust of armature shaft 9 is less than
Pretightning force, valve element 11 will not be slided.As control electric current increases, the thrust of armature shaft 9 is more than spring force, and valve element 11 starts to produce fortune
Dynamic, when the thrust of armature shaft 9 is equal to spring force, valve element 11 is in a relative settling position.
Because the valve pocket switch side 5.4 on the metering orifice 11.1 and valve pocket 5 of valve element 11 has misalignment margin, valve pocket when initial
Switch side 5.4 will not also produce circulation area with valve element metering orifice 11.1, and now flow is still closing.When change control electric current,
Valve element 11 slides into another new relative settling position, and valve pocket switch side 5.4 starts to produce circulation with valve element metering orifice 11.1
Area, fuel oil by when start to produce flow, now correspond to flow valve starting current.By adjusting control electric current size, change
Valve pocket switchs the amount of covering of side 5.4 and valve element metering orifice 11.1, thus change fuel oil by when circulation area, realize to flow
The precise control of valve flow.
