Oilhole 6, armature lever mesoporous 4, oil outlet 3 leaks into the chamber armature chamber 21 of low pressure on armature lever；At the same time, with armature 2,
The lifting of armature lever 7, the armature lever circular passage 27 that armature lever annular groove 5 is formed with control valve seat 18 are gradually reduced, until disappear,
To block high pressure oil to continue to pour in control chamber 16, reduce the loss of high pressure fuel.Pass through the above-mentioned course of work, control
Fuel pressure in chamber 6 can decline rapidly, and the downward hydraulic coupling suffered by the top of control piston 8 is less than suffered by needle-valve upwards
Hydraulic coupling when, needle-valve open realize oil spout.
When the electromagnet is powered off, as shown in Fig. 2,3,5, electromagnetic force disappears, and armature 2, armature lever 7 are in electromagnet spring 22
Lower downlink is acted on, during the decline of armature lever 7 conical surface 26 under armature is in contact with the sealing cone 20 of control valve seat 18, hinders
Broken the high pressure oil approach that oil outlet 3 leaks to armature chamber 21 from armature lever；At the same time, armature lever annular groove 27 and control valve
Seat 18 gradually forms armature lever circular passage 27, and high pressure oil is through meter in hole 7, armature lever annular groove 27, armature lever circular passage
27 are flowed into control chamber 16, and the pressure in control chamber 16 gradually increases, when it acts on the hydraulic coupling of control 8 upper surface of piston
When greater than hydraulic coupling in phase suffered by needle-valve, needle-valve downlink is taken a seat, and injection process terminates.
