The electromagnetic valve applied to the automatic transmission also has various models and characteristics due to different manufacturers and characteristics of the transmission. In the automatic transmission model for the middle and small displacement model, the working pressure of the proportional solenoid valve is lower because the transmission torque is smaller. The spill type inverse proportional pressure reducing solenoid valve has a higher anti-contamination capability than the spool type proportional solenoid valve, can provide accurate pressure regulation in a lower pressure range, and is thus widely used in automatic transmissions. In the actual use process of the transmission, a filter system of a hydraulic system of the transmission cannot completely remove metal impurities in oil, and the situation of filtration failure often occurs along with the increase of the service life of a vehicle, so that a proportional solenoid valve for controlling pressure is polluted by working media, a large amount of pollutants enter a main valve and are continuously gathered, the space required by the work in the solenoid valve is occupied by the pollutants, the moving capacity of components such as an armature of the solenoid valve is lost, and the working capacity of the solenoid valve is lost. In addition, the abrasion of moving parts in the electromagnetic valve is aggravated due to pollution, the electromagnetic valve can still realize the pressure regulation function, but the overall performance of the electromagnetic valve is obviously reduced, a valve core of the control pressure is easy to generate a destabilization state to cause large fluctuation of the control pressure and even obvious deviation from a set value, the vehicle has faults of large gear shifting impact, slow gear shifting action, vehicle shaking and the like in the driving process, and the vehicle cannot normally drive.

One end of the armature 6 is provided with a flat-bottom hole 16, the surface of the valve core 2 is provided with an annular groove 15, and the bottom of the flat-bottom hole 16 deforms and is embedded into the annular groove 15 on the valve core 2 when the valve core 2 is riveted with the armature 6. The bearings 5 are of an integral structure, and the valve core 2 reciprocates between the two bearings 5 during operation. And an input signal connector is arranged on the coil 8. When the electromagnetic valve is electrified and works, an attraction force is generated between the armature 6 and the stop iron 9, and the armature 6 moves leftwards to overcome the elastic force generated by the compression adjusting spring 13 and then is balanced with the hydraulic pressure fed back by the valve core 2. The working principle of the valve is as follows: as shown in fig. 3, a damping hole is arranged in front of the port a of the solenoid valve control port, and the damping hole is directly a structural set value. The medium is supplied from the system pressure supply port P through the damping arranged between the port P and the port AThe orifice flows to port a. In the non-energized state, the valve core 2 is under the spring force of the adjusting spring 13The medium flowing from the port P to the port A through the damping hole is accumulated at the port A to form pressurePressure of the pressureThe same as the pressure at port P.Acting on the spool 2 to produce a hydraulic force to the leftThe pressure action area is the circular cross-sectional area inside the valve body 1。

Because the armature 6 is riveted with the valve core 2, the valve core 2 moves leftwards. At this time, the sealing structure between the valve element 2 and the valve body 1 is changed, and the medium part flowing from the port P to the port A through the damping hole is discharged from the channel between the valve body 1 and the valve element 2 from the port T.
