Description
Technical field:
A kind of it can shorten the invention patent relates to use for diesel engine electric-control common-rail type fuel injector more particularly to simultaneously atomizer and open
The common-rail injector for closing delay time is more particularly to injector nozzle matching parts therein.
Background technique:
Existing high pressure common rail injector is all transmitted using long valve rod, and slow in reacting, structure is complicated, and cannot realize simultaneously
Opening time and shut-in time are reduced, power density is small, and volume and weight has the space of diminution, is not able to satisfy energy-efficient bavin
The mating requirement of oil machine, therefore, applicant devise a kind of hydraulic control rapid response type high pressure common rail injector, utilize specific structure
Armature, armature seat, valve seat and oil nozzle couple form the hydraulic control system of oil spout opening and closing automatic adjustment, this control system spray
Oil nozzle couple can be achieved with quickly starting and closing without the driving of valve rod rigid mechanical, when shortening the delay of opening and closing
Between, improve power density.This hydraulic control rapid response type high pressure common rail injector applicant separately protects, structure such as Fig. 1-
Shown in Fig. 5, it includes electromagnetic actuator 1, upper spring 2, armature 3, armature seat 4, valve seat 5, lower spring 6, oil nozzle valve body 7, oil nozzle
Needle 8, tight cap 9 and injector body 10, it is armature 3, armature seat 4, valve seat 5 and oil nozzle needle 8 that wherein core, which improves part,.
Its working principles are as follows:
High pressure fuel in common rail pipe entered by main fuel feed hole 11, pedestal fuel feed hole 41, valve seat fuel feed hole 55, couple
Fuel feed hole 71 and couple high pressure chest 72 constitute asphalt channel, upper pressure oil cavity 12 by upper throttle orifice 44, lower end oil suction chamber 46 with
Valve seat fuel feed hole 41 communicates, and high-pressure channel 53, center cavity 54 are communicated by lower throttle orifice 52 with couple fuel feed hole 71, couple high pressure
Chamber 72 is communicated by vertical throttle orifice 51 with lower end oil suction chamber 46.
When 1 power loss of electromagnetic actuator, due to upper spring 2 pretightning force F1 act on, the sealing cone section 31 of armature 3 with
42 mechanical seal of taper hole face of armature seat 4 cooperates；Under conditions of not considering restriction loss, high-pressure channel 53 and couple are high at this time
Press the liquid pressure in chamber 72 identical as the pressure in common rail pipe, since high-pressure channel 53 is applied to the downward liquid of oil nozzle needle 8
The forced area S1 of pressure F2 is applied to the forced area S2 of the upward hydraulic coupling F3 of oil nozzle needle 8 than couple oil outlet chamber 13
Greatly, therefore F2 > F3, the resultant force of the hydraulic action F2 of the high pressure fuel in the pretightning force F4 and high-pressure channel 53 of lower spring 6
Under effect, F4+F2 > F3, oil nozzle needle 8 is sealed on the seat surface of oil nozzle valve body 7, and fuel injector is in close state, oil spout
Device not oil spout；
When fuel injector needs oil spout, electromagnetic actuator 1 must be electric, and electromagnetic actuator 1 is applied with upward electromagnetism to armature 3
Suction F5, electromagnetic attraction F5 overcome the pretightning force F1 of upper spring 2, and the sealing cone section 31 of 3 uplink of armature, armature 3 leaves armature
The taper hole face 42 of seat 4, the liquid pressure in access ramp 43 reduce rapidly, the height due to the effect of pressure difference, in high-pressure channel 53

Font face, fuel injector realize fuel oil injection.The trunon delay time T1 of injection depends on flow-rate ratio a, S1, S2, F4；Compared to relatively often
The fuel injector of the electronic control common rail oil sprayer of rule, this programme design eliminates the intermediate mechanical transmission mechanism similar to valve module, by
Fluid pressure in high-pressure channel 53 changes the force controlled directly to oil nozzle needle 8, thus can bring three benefits: first is that subtracting
Lack delay time caused by transmission mechanism movement, improves response speed；Two are the reduction of since transmission mechanism movement causes
The performance and stability to injector assembly influence, improve the stability of injector assembly；Third is that eliminating transmitting machine
The manufacturing cost of structure；
At the end of fuel injector injection needs, the voltage that electromagnetic actuator 1 applies is cut off, electromagnetic force F5 disappears, by
It is forced on the taper hole face 42 of armature seat 4 in the sealing cone section 31 of the effect of the pretightning force F2 of upper spring 2, armature 3, it is tiltedly logical
The pressure release passage in road 43 is closed, and high pressure fuel enters high-pressure channel 53, another way high pressure fuel by lower throttle orifice 52 all the way
It is transmitted to vertical throttle orifice 51 by upper throttle orifice 44, lower end oil suction chamber 46 also to enter in high-pressure channel 53, at this time high-pressure channel
Liquid pressure in 53 rises rapidly, and when rising to F4+F2 > F3, oil nozzle needle 8 is sealed in the seat surface of oil nozzle valve body 7
On, fuel injector injection is closed；Spray the flow that turn-off delay time T2 depends on flow-rate ratio a, S1, S2, F4 and upper throttle orifice 44
Speed A3；Compared to the valve rod mechanical transfer mechanism of the valve module in more existing common-rail injector, at the end of spraying needs, high pressure
Fuel oil can also enter high-pressure channel by vertical throttle orifice 51 other than it can enter high-pressure channel 53 by lower throttle orifice 52
53, the strong promotion speed of 53 internal combustion oil pressure of high-pressure channel is which thereby enhanced, and then reduce and reach F4+ required for injection is closed
The time of this condition of F2 > F3, that is, reduces turn-off delay time T2, further improve response speed.Wherein, atomizer
Couple is the core component of fuel injector.
