Detailed ways:

As shown in the figure: the electromagnetic coil 4 is wound on the non-metallic skeleton 5, and the armature 37 is fixed in the magnetizer 2. The periphery of the electromagnetic coil 4 is wrapped with an insulating material 3, and the armature 37 is connected with one end of the fourth spring 35. The fourth The other end of spring 35 links to each other with permanent magnet 6, and permanent magnet 6 is fixed with one end of first one-way valve 7, and the other end of first one-way valve 7 is fixed with one end of baffle plate 32, and the other end of baffle plate 32 It is connected with one end of the second spring 25, and the other end of the second spring 25 is connected with the third one-way valve 16. The fuel 11 flows into the annular groove 9 along the oil inlet 10, and the fuel 11 exerts force on the first valve ball 13. pressure, the first valve ball 13 will exert pressure on the first spring 14 after receiving the pressure, the first spring 14 is forced to shorten, and the fuel 11 enters the pressure chamber 31 through the channel 15, and feeds into the electromagnetic coil 4 Wave power signal 38 will cause a strong interaction between the electromagnetic coil 4 and the permanent magnet 6. When a strong repulsive force is generated between the electromagnetic coil 4 and the permanent magnet 6, the first one-way valve 7 will also be pushed after being pushed. Pressure will be applied to the fuel oil 11 in the pressure chamber 31, and the fuel oil 11 will generate pressure on the first one-way valve 7 and the second one-way valve 12 after being under pressure. The second one-way valve 12 applies pressure, so only a very small amount of fuel oil 11 enters the air chamber 36 through the first one-way valve 7, and flows back into the annular 9 groove through the second one-way valve 12, and the same fuel oil 11 will also Apply pressure to the third one-way valve 16, fuel oil 11 exerts pressure on the second valve ball 27, and the second valve ball 27 compresses the second spring 25 after receiving pressure, and the second spring 25 is forced to shorten, so that the fuel oil 11 is released from the pressure chamber. 31 is pressed into the high-pressure passage 24, because the fuel 11 in the high-pressure passage 24 is under strong pressure, it will quickly flow into the arc passage 20 from the oil passage 23 of the V-shaped nozzle body 19, and finally the fuel 11 Forced to spray out from the V-shaped hole 21 in an atomized state. When there is a strong attractive force between the electromagnetic coil 4 and the permanent magnet 6, the first check valve 7 will move in the opposite direction after receiving the attractive force, so that the pressure of the fuel 11 in the pressure chamber 31 is rapidly reduced, and the outside world The fuel oil 11 will flow into the annular groove 9 along the oil inlet 10, and the fuel oil 11 will exert pressure on the first valve ball 13, and the first valve ball 13 will exert pressure on the first spring 14 after being pressurized, and the first valve ball 13 will exert pressure on the first spring 14. Once the spring 14 is forced to shorten, the fuel 11 enters the pressure chamber 31 from the passage 15 to prepare for the next fuel injection, thus completing a complete fuel injection. Next, the fuel injection device will cycle the above-mentioned actions. The cavity 33 plays a role of fixing the second one-way valve 12 , the plunger sleeve 8 , the third one-way valve 16 and the front end 18 . The first O-ring 30 plays the role of sealing the fuel 11, so that the fuel 11 cannot overflow from the contact between the housing 1 and the cavity 33; The contact of 33 overflows; the plunger sleeve 8 prevents the fuel oil 11 from overflowing from the contact of the check valve and the plunger sleeve 8; the thread 28 fixes the front end 18 and the housing 1 together.
