There are two ways to use the maintenance solenoid valve of Jinan automatic transmission. One method is to properly open the gear oil circuit under the control of microcomputer system, so as to change the working pressure at one end of the hydraulic valve, promote the rotary vane pump to move and manipulate the relevant gear oil circuit transformation. This kind of solenoid valve is power switch type two-way solenoid valve. This kind of application method is called the function formula of hydraulic valve, which can be summarized as: automatic transmission microcomputer → solenoid valve → hydraulic valve → actuator fuel pipe → actuator. Another way to use the solenoid valve of automatic transmission is to properly adjust the change of gear oil circuit and the working pressure of hydraulic oil under the control of microcomputer system, and to operate the related hydraulic press to fill or drain the components.

这类种类的速比电磁阀一般为占空比型三通电磁阀。微机以适合的占空比数据信号操纵速比电磁阀调整液压油工作压力转变，以完成液压机实行元器件的紧密连接、分离出来姿势。这类运用方法为执行器功效式，能够归纳为：自动变速箱微机→电磁阀→执行器燃油管→执行器。

This kind of speed ratio solenoid valve is generally duty cycle type three-way solenoid valve. The microcomputer controls the speed ratio solenoid valve with suitable duty cycle data signal to adjust the working pressure change of hydraulic oil, so as to realize the close connection of components and separation posture of hydraulic press. This kind of application method is the function of actuator, which can be summarized as: automatic transmission microcomputer → solenoid valve → actuator fuel pipe → actuator.

速比电磁阀的运用有液压阀功效式和执行器功效式2种方法，液压阀功效式是速比电磁阀在微机系统控制下适度导通齿轮油路，使功效在自动变速箱液压传动系统全自动换挡阀一端的工作压力产生变化，促进旋片泵挪动，操纵相关的液压机实行元器件充油或泄油，完成速比变换。这类种类的速比电磁阀一般有两个之上，为电源开关型二通电磁阀。

The application of speed ratio solenoid valve has two methods: hydraulic valve function type and actuator effect type. The function type of hydraulic valve is that the speed ratio solenoid valve can properly open the gear oil circuit under the control of microcomputer system, so as to change the working pressure at one end of the automatic shift valve in the hydraulic transmission system of automatic transmission, promote the movement of rotary vane pump, operate the relevant hydraulic machine to charge or discharge oil components Speed ratio conversion. This kind of speed ratio solenoid valve generally has two above, for the power switch type two-way solenoid valve.

速比电磁阀运用的另一种方法是执行器功效式，速比电磁阀在微机系统控制下，适度调整齿轮油路变换和液压油工作压力转变，操纵相关的液压机实行元器件充油或泄油，完成速比变换。这类种类的速比电磁阀一般为占空比型三通电磁阀。微机以适合的占空比数据信号操纵速比电磁阀调整液压油工作压力转变，可完成液压机实行元器件的紧密连接、分离出来姿势较为理想。

Another way to use the speed ratio solenoid valve is the actuator function type. Under the control of the microcomputer system, the speed ratio solenoid valve moderately adjusts the gear oil circuit transformation and the hydraulic oil working pressure change, operates the related hydraulic press to implement the component oil filling or oil discharging, and completes the speed ratio conversion. This kind of speed ratio solenoid valve is generally duty cycle type three-way solenoid valve. The microcomputer controls the speed ratio solenoid valve with suitable duty cycle data signal to adjust the working pressure change of hydraulic oil, which can realize the close connection and separation of components and parts of the hydraulic press.

锁止电磁阀的作用是操纵变扭器的锁止离合紧密连接或分离出来。选用液压阀功效式或执行器功效式。在微机系统控制下，锁止电磁阀适度导通齿轮油路，调整锁止离合继动阀姿势转换燃油管或立即转换燃油管，使锁止离合姿势，完成机械设备锁止或软性锁止。锁止电磁阀一般有一个或两个，为电源开关型、占比型或占空比型电磁阀。

The function of the lock up solenoid valve is to operate the locking clutch of the torque converter to be tightly connected or separated. Select the function type of hydraulic valve or actuator. Under the control of microcomputer system, the locking solenoid valve can properly open the gear oil circuit, adjust the position of the lock clutch relay valve, change the fuel pipe or immediately change the fuel pipe, so as to lock the clutch position and complete the mechanical equipment locking or soft locking. There are generally one or two locking solenoid valves, which are power switch type, duty cycle type or duty cycle type.
