Signal Regulation high-pressure oil pump fuel oil suction volume, thus control the split type fuel metering valve of high pressure co-rail system pressure.
Background technology
The fuel oil suction volume control valve valve body of HP3 diesel oil high pressure co-rail system uses overall manufacture processing, because of valve body
For small-bore, deep blind hole, the high requirement of machining accuracy, so the requirement to process equipment and human users's technical ability is the highest, often
The machining equipment of rule cannot meet mass production requirement, needs to put into deep blind hole grinding special equipment, and disposable input is relatively big, in
Small enterprise's pressure is bigger.
Summary of the invention
The purpose of the present invention is to propose to a kind of split type fuel metering valve, the valve body of deep for small-bore blind hole is changed into split type
Valve body, solves difficult processing, a difficult problem high to process equipment and human users's skill set requirements, and it is reasonable in design, simple for production, becomes
This is low, promotes the market competitiveness, reduces 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:

Accompanying drawing explanation
Fig. 1 is the schematic diagram of split type fuel metering valve of the present invention.
Detailed description of the invention
Below preferred embodiment of the invention is described in further detail.
As it is shown in figure 1, described split type fuel metering valve, including shell 2, rear yoke 3, coil block 4, spring 6, valve
Body 8, spool 9, back-up ring 11, terminal base 12, described shell 2 one end joint end Stroma 12, shell 2 other end clamping valve body 8, valve body
8 are provided with the structure of through hole for middle part, and processing is simple, socket spool 9 in valve body 8, and spool 9 one end is connected to valve body by back-up ring 11
Inside 8 outer ends, overhead spring 6 one end in the groove that spool 9 is additionally provided with, described spring 6 other end overhead is in the scrobicula of rear yoke 3
In groove, the shallow grooves processing of rear yoke 3 is simple, and precision is high, and described rear yoke 3 is oppositely arranged inside valve body 8, and rear yoke 3
Being connected in coil block 4 with valve body 8 inner sleeve, coil block 4 is socketed in shell 2.
It is provided with sealing ring 5 between described coil block 4 and rear yoke 3.
It is provided with sealing ring 7 between inside described coil block 4 and valve body 8.
It is provided with terminal 1 in described terminal base 12.
Sealing ring 10 it is socketed on outer circle wall outside described valve pocket 8.
High pressure co-rail system low-voltage fuel is flowed into inside valve by valve body 8 end, then flows out to high-pressure oil pump through valve port and enter
Oil end, valve port opening receives vehicle speed sensor, engine speed according to engine high pressure common rail system electronic control unit (ECU)
The signals such as sensor, cooling-water temperature sensor, common rail pressure sensor, comparison MAP carries out pulse width modulated wave (PWM) output and controls fuel oil
Suck the size of the proportion electro-magnet input current of control valve, drive spool 9 to coordinate spring 2 to realize moving left and right regulating fuel oil
Suck the A/F of control valve, thus control the oil inlet quantity of high-pressure oil pump, reach to control the purpose of high pressure co-rail system rail pressure.
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.
