Wherein, the elastic force of the first elastic component 3 is more than the second elastic component 10.For example, the first elastic component 3 and the second elastic component 10
It is spring, the first elastic component 3 is in compressive state between armature 1 and lifting core 7, produces downward elastic force；Second elasticity
Part 10 is in compressive state between hook arm 9-5 and lifting core 7, produces elastic force upwards；The elastic force of the first elastic component 3 is more than the
The elastic force of two elastic components 10, thus first passage 7-5 and sealing 4-1, the bottom of lifting core 7 when ensure that electromagnetic valve is not powered on
All keep contacting with the bottom of sleeve pipe, it is to avoid the leakage of hydraulic oil.
When the electromagnetic valve of the present embodiment uses, especially apply in automobile electronic stabilization system:
Under normal circumstances, when that is, electromagnetic valve solenoid is not powered on, the elastic force due to the first elastic component 3 is more than the second bullet
Property part 10 elastic force, dynamic iron core 4 moves down towards lifting core 7, makes the sealing 4-1 of dynamic iron core 4 bottom and lifting core 7 top
Sealing cooperation, i.e. first passage 7-5 closure；Dynamic iron core 4 promotes dynamic lifting core 7 towards pump inlet passage 30-2 to moving down simultaneously
Dynamic, so that lifting core 7 bottom is coordinated with valve seat 9 bottom end seal, i.e. second channel 9-4 closure.
In the case of the energising of electromagnetic valve solenoid, if master cylinder passage 30-1 is in low hydraulic coupling state, armature 1 produces
Raw electromagnetic force and the second elastic component 10 elastic force overcome the elastic force of the first elastic component 3 and master cylinder passage 30-1 and pump inlet to lead to
Pressure differential between road 30-2, makes dynamic iron core 4 move up towards armature 1, the sealing 4-1 of dynamic iron core 4 bottom with lifting core 7
Top generation gap, that is, first passage 7-5 open, so that the oil-in that hydraulic oil passes through on dynamic iron core support 6 is logical from first
Road 7-5 flows into pump inlet passage 30-2；After dynamic iron core 4 rises setpoint distance, by the first limiting section 6- on dynamic iron core support 6
1 is coordinated with the second limiting section 7-3 conflict on lifting core 7, and dynamic iron core 4 drives lifting core 7 to move up towards armature 1 direction,
Make lifting core 7 bottom and valve seat 9 bottom generation gap, that is, second channel 9-4 opens, so that hydraulic oil passes through second channel 9-
4 inflow pump inlet passage 30-2.
In the case of the energising of electromagnetic valve solenoid, if master cylinder passage 30-1 is in high hydraulic coupling state, due to master
Pressure differential between cylinder passage 30-1 and pump inlet passage 30-2 is very big, electromagnetic force and the second elastic component 10 that armature 1 produces
Elastic force can only overcome the elastic force of the first elastic component 3 can not overcome the pressure between master cylinder passage 30-1 and pump inlet passage 30-2
Difference, thus dynamic iron core 4 can only be made to move up towards armature 1, makes the sealing 4-1 of dynamic iron core 4 bottom and lifting core 7 top produce
Give birth to gap, that is, first passage 7-5 opens, make hydraulic oil pass through the oil-in on dynamic iron core support 6 and flow into pump from first passage 7-5
Intake channel 30-2；Because lifting core 7 can not be driven, lifting core 7 bottom and valve seat 9 bottom still seal cooperation, and that is, second
Passage 9-4 closes；When hydraulic oil by first passage 7-5 flow into pump inlet passage 30-2 for a period of time after, master cylinder passage 30-1
Pressure differential and pump inlet passage 30-2 between can drop to below predetermined value, and dynamic iron core 4 passes through first on dynamic iron core support 6
Limiting section 6-1 is coordinated with the second limiting section 7-3 conflict on lifting core 7, drives lifting core 7 to move towards armature 1 direction, makes to carry
Rise core 7 bottom and valve seat 9 bottom generation gap, that is, second channel 9-4 opens, so that hydraulic oil is flowed by second channel 9-4
Enter pump inlet passage 30-2.
In the case of the energising of electromagnetic valve solenoid, if master cylinder passage 30-1 is in no pressure or the relatively low state of pressure
When, the elastic force of electromagnetic force and the second elastic component 10 that armature 1 produces overcome the elastic force of the first elastic component 3 and master cylinder passage 30-1 and
Pressure differential between pump inlet passage 30-2, makes dynamic iron core 4 move up towards armature 1 rapidly, the sealing of dynamic iron core 4 bottom
4-1 is opened with lifting core 7 top generation gap, i.e. first passage 7-5；Due to master cylinder passage 30-1 and pump inlet passage 30-2 it
Between pressure differential relative to electromagnetic force very little, under the elastic force of the second elastic component 10 acts on, lifting core 7 moves upwards towards dynamic iron core 4
Dynamic, make sealing 4-1 and the lifting core 7 end sealing cooperation of dynamic iron core 4 bottom, that is, first passage 7-5 closes, meanwhile, lifting
Core 7 bottom and valve seat 9 bottom generation gap, that is, second channel 9-4 open, so that hydraulic oil is flowed into by second channel 9-4
Pump inlet passage 30-2.
The present invention, by supporting the second elastic component using the hook arm above second channel, makes second channel enter to pump
The conveyance capacity that runner between mouth passage is unblocked, substantially reduces flow resistance, enhance electromagnetic valve；Also reduce simultaneously
Parts in electromagnetic valve, reduce the volume and weight of electromagnetic valve, greatly reduce cost；Other second elastic component adopts
