It is provided with steel ball 3 between spool 2 and cartridge cover 21, matches control P mouths 11 and A with the oil inlet 2a of spool 2 by steel ball 3
Break-make between mouthfuls 12, to control the keying of solenoid valve.A centrally disposed mandril 61 for dynamic iron core 6, dynamic iron core 6 is in spring
The effect of 7 elastic force, and so that steel ball 3 is matched with the oil inlet 2a of spool 2 by mandril 61.
When the coil block 4 of electromagnet assembly is not powered on, the elastic force of spring 7 pushes away dynamic iron core 6 to the left, then by moving iron
The mandril 61 at 6 center of core pushes up steel ball 3 to the left, so that the oil inlet 2a of steel ball 3 and spool 2 is formed and seals, thus by P mouths 11 and A
Separate between mouth 12, at this moment solenoid valve is just closed.
After the coil block 4 of electromagnet assembly is powered, coil block 4 generates electromagnetic force, and dynamic iron core 6 is made to overcome spring 7
Elastic force move right, dynamic iron core 6 move to right drive mandril 61 move to right, make mandril 61 be detached from steel ball 3；Steel ball 3 is losing top
It after the active force of bar 61, is washed open by the oil pressure of P mouths 11, and then is detached from oil inlet 2a, sealing is led by broken ring, P mouths 11 and A mouths 12
Logical, at this moment solenoid valve is just in open state.
After power-off, dynamic iron core 6 loses the effect of electromagnetic force, just moves to left under the effect of the elastic force of spring 7, finally makes again
The oil inlet 2a of steel ball 3 and spool 2 forms sealing again, and solenoid valve is closed；And remaining oil pressure is then from 13 row of T mouths in spool 2
Go out.
Since steel ball 3 can only move between spool 2 and cartridge cover 21,6 need of dynamic iron core of this solenoid valve are extremely short
Stroke can realize the control opened and closed to solenoid valve, keep this solenoid valve control sensitive, fast response time.
Highly preferred embodiment of the present invention has illustrated, and the various change or remodeling made by those of ordinary skill in the art are not
It can depart from the scope of the present invention.
