Background technology
At present, disassembling analysis according to market return, about 30% fault part causes height for this valve cleaning inside degree is poor
The spool of precision-fit and valve pocket clamping stagnation, affect valve assembly high speed response property, thus cannot meet electromotor to dynamic property, combustion
Oil economy, the requirement of exhaust emissions.
Summary of the invention
The purpose of the present invention is to propose to a kind of fuel metering valve carrying accurate filter screen, it is reasonable in design, simple for production, becomes
This is low, promotes the market competitiveness；Oil inlet end at quantity control valve adds accurate filter screen, can effectively filter engine oil path and
Impurity in fuel, it is to avoid impurity enters inside valve, causes valve module clamping stagnation to lose efficacy, and governed engine speed maybe cannot start；Simultaneously can
To avoid a part of minute impurities to enter in valve module fit clearance, cause spool or the abnormal scuffing of valve pocket, premature abrasion, reduce
The service life of quantity control valve.
In order to reach above-mentioned purpose of design, under the technical solution used in the present invention:
A kind of fuel metering valve carrying accurate filter screen, including filter screen, shell, coil block, back-up ring, valve pocket, spool, bullet
Spring, described shell inner sleeve wiring coil assembly, it is provided with valve pocket in coil block, valve pocket is extended out by shell one end, and at its end
End is provided with filter screen, described shell other end joint end Stroma；Socket spool in described valve pocket, spool one end extends to valve pocket end
End, and fix by being connected to the back-up ring of valve pocket end, it is provided with spring between the spool other end and valve pocket.
Preferably, described filter screen includes nylon rack and stainless steel cloth, and stainless steel cloth is socketed in nylon rack.
Preferably, it is provided with terminal in described terminal base.
Preferably, the outer circle wall that described valve pocket is extended out by shell one end is socketed sealing ring.
The fuel metering valve carrying accurate filter screen of the present invention provides the benefit that: at the oil inlet end of quantity control valve
Add accurate filter screen, can effectively filter engine oil path and impurity in fuel, it is to avoid impurity enters inside valve, causes valve module card
Stagnant and lost efficacy, governed engine speed maybe cannot start；A part of minute impurities can be avoided to enter in valve module fit clearance simultaneously,
Cause spool or the abnormal scuffing of valve pocket, premature abrasion, reduce the service life of quantity control valve.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the fuel metering valve carrying accurate filter screen of the present invention；
Fig. 2 is the sectional view of the fuel metering valve carrying accurate filter screen of the present invention；
Fig. 3 is the schematic diagram of the filter screen of the fuel metering valve carrying accurate filter screen of the present invention.
Detailed description of the invention
Below preferred embodiment of the invention is described in further detail.
As Figure 1-3, the described fuel metering valve carrying accurate filter screen, including filter screen 1, shell 3, coil block 4,
Back-up ring 5, valve pocket 6, spool 7, spring 8, described shell 3 inner sleeve wiring coil assembly 4, be provided with valve pocket 6 in coil block 4, valve pocket 6 by
Shell 3 one end extends out, and is provided with filter screen 1, described shell 3 other end joint end Stroma 10 at its end；In described valve pocket 6
Socket spool 7, spool 7 one end extends to valve pocket 6 end, and fixes by being connected to the back-up ring 5 of valve pocket 6 end, spool 7 another
It is provided with spring 8 between end and valve pocket 6.
Described filter screen 1 includes nylon rack 11 and stainless steel cloth 12, and stainless steel cloth 12 is socketed in nylon rack 11.
It is provided with terminal 9 in described terminal base 10.
Sealing ring 2 it is socketed by shell 3 one end on the outer circle wall that described valve pocket 6 is extended out.
Operation principle is: high pressure co-rail system low-voltage fuel is flowed into inside valve by the accurate filter screen 1 of valve pocket 6 end, then
Flowing out to high-pressure oil pump oil inlet end through valve port, valve port opening connects according to engine high pressure common rail system electronic control unit (ECU)
Receiving the signals such as vehicle speed sensor, engine speed sensor, cooling-water temperature sensor, common rail pressure sensor, comparison MAP carries out pulsewidth
The size of modulating wave (PWM) output control quantity control valve electromagnetic force changes the A/F of the valve position control of spool 7, from
And control the oil inlet quantity of high-pressure oil pump, reach to control the purpose of high pressure co-rail system rail pressure.
This quantity control valve, on the basis of original valve pocket 6, is integrated with accurate filter screen 1 at oil inlet end, and this structure only need to be
One peripheral groove of original valve pocket 6 multi-processing, processing technique is simple, and cost is relatively low, reliable in quality；Accurate filter screen 1 uses rustless steel
Silk screen is molded into nylon entirety, and technique is simple, cost is relatively low, reliable in quality；Accurate filter screen 1 uses press-fit approach to load valve pocket 6
In peripheral groove, operation is simple and reliable.Accurate filter screen 1 can effectively filter engine oil path and impurity in fuel, it is to avoid impurity enters
Inside valve, causing valve module clamping stagnation to lose efficacy, governed engine speed maybe cannot start；A part of minute impurities can be avoided to enter simultaneously
Enter in valve module fit clearance, cause spool 7 or the abnormal scuffing of valve pocket 6, premature abrasion, reduce the use longevity of quantity control valve
Life.
Above content is to combine the further description that the present invention is done by concrete preferred implementation, it is simple to this skill
The technical staff in art field is understood that and applies the present invention, it is impossible to assert the present invention be embodied as be confined to these explanations.
For general technical staff of the technical field of the invention, can also make without departing from the inventive concept of the premise
Some simple deduction or replace, without through performing creative labour.Therefore, those skilled in the art's taking off according to the present invention
Showing, the simple modifications making the present invention all should be within protection scope of the present invention.
