Description
Technical field
The present invention relates to electric-controlled fuel injector internal structure, specially a kind of fuel injector armature quick response structure.
Background technology
Fuel injector is applied to pulsating liquid delicate metering and atomization, such as engine fuel metering and Combustion System, fuel injector
Receive the fuel injection pulse signal that ECU (electronic control unit) is sent, accurately control fuel injection amount.
The structure of fuel injector is mainly made up of electromagnetic mechanism, valve body mechanism, atomising mechanism, metrological service and runner mechanism.
Fuel injector oil spout quick response is an important technology index, is embodied in the responsiveness of armature adhesive and return
On.In conventional valve body mechanism structure, the iron core tube connection ball valve of armature bottom, the footpath for opening up use of the iron core tube upper runner
To flowing hole, oily flow path to the mobile obstacle axial movement of armature, be to cause armature reaction speed not improve further
Major reason.
The content of the invention
In view of the shortcomings of the prior art, the technical problems to be solved by the invention are to propose a kind of further raising armature
The fuel injector armature quick response structure of reaction speed.
The fuel injector armature quick response structure of above-mentioned technical problem is can solve the problem that, its technical scheme, which is included at nozzle, to be set
The valve body structure put, the valve body structure is included with armature, ball valve and the valve seat being located in plunger tube, except that described
The pipe and lower cone of armature including top angularly under Taper Pipe, formed flow cone chamber, Taper Pipe between the Taper Pipe and plunger tube
Upper circumference uniform distribution offers axial flowing hole and communicated with crossing flow cone chamber, and the ball valve is located at Taper Pipe bottom, the pipe internal pressure
Equipped with return spring, under the elastic force effect of return spring, ball valve is pressed downward tightening seal on valve seat with crossing flow cone chamber by armature
In the circular cone fuel feed hole communicated.
The Taper Pipe cone angle of the armature is preferably 50 °~80 °.
Beneficial effects of the present invention：
In fuel injector armature quick response structure of the present invention, excessively stream duct is axially opened up on the Taper Pipe of armature bottom, with for
For the radial flow path of traditional structure, the flow resistance of fluid is reduced, the axial movement velocity of armature is improved, reduces fuel injector

Embodiment
Illustrated embodiment is described further to technical scheme below in conjunction with the accompanying drawings.
Fuel injector armature quick response structure of the present invention, its technical scheme includes being located at the nozzle of fuel injector 8 (A) place plunger tube
The valve body structure of 1 time mouth, the valve body structure includes armature 2, ball valve 3, valve seat 4 and the deflector 9 being coaxially disposed from top to bottom,
As shown in Figure 1 and Figure 2.
The armature 2 includes top pipe and the Taper Pipe (cone angle is downward) of bottom, between the Taper Pipe and plunger tube 1 of armature 2
Formed and return spring 5 is pressed with flow cone chamber 7, the pipe of armature 2, the ball valve 3 is fixed on the lower cone ttom of pipe of armature 2
Portion, under the elastic force effect of return spring 5, ball valve 3 is pressed and sealed in the circular cone fuel feed hole opened up at the top of valve seat 4 by armature 2,
The circular cone fuel feed hole connected and uniformly offers tiny oblique nozzle opening 10, deflector 9 on flow cone chamber 7, the deflector 9
Diversion cavity 11 is formed between the bottom of valve seat 4, the diversion cavity 11 is communicated with the circular cone fuel feed hole of valve seat 4 upwards, such as Fig. 2
It is shown.
Circumference uniform distribution offers axial flowing hole 6 on the Taper Pipe of the armature 2, and the flowing hole 6 connected flow cone chamber
7, as shown in Figure 2.
Preferably 50 °~80 ° of the Taper Pipe cone angle of the armature 2.
The present invention injection mode be：
When electric drive loop adds control signal, armature 2 overcome the elastic force of return spring 5 upwards with the adhesive of iron core 12,
Armature 2 drives ball valve 3 to open the circular cone fuel feed hole on valve seat 4, and oil stream is stored by the circular cone fuel feed hole of valve seat 4 into diversion cavity 11
Pressure, pressure oil outwards sprays mist of oil from the nozzle opening 10 of deflector 9 again.
