Nissan JF015E valve body

The function of the transmission valve body on the car is to switch between high and low gears. When the vehicle speed reaches a certain gear speed, the hydraulic oil pushes the valve body to automatically change the gear to this gear.

I believe everyone knows about valves, but do you know what a valve body is? Indeed, few of us will understand the structure of the valve in detail, and the valve and the valve body are not the same thing, and the valve body is a main component of the valve. There are different mechanical manufacturing methods according to the pressure level. You can see from this question that the Transmission Valve Body And Mechatronics still have certain requirements in terms of workmanship.

The functions of the transmission throttle body: 1. To increase power through acceleration or deceleration; 2. To correct the air intake function through its self-regulation; 3. To control the operation of the engine assembly; 4. To control the flap, through the sensor Work to control the size of the intake air for power improvement.

The function of the throttle valve is to output throttle oil pressure according to the opening (load) of the engine throttle valve. The greater the load, the higher the output oil pressure. It is mainly used to adjust the main oil line oil pressure and accumulator back pressure. There are two slide valves in the throttle valve body. The lower one is the throttle valve and the upper one is the feedback valve. There is a spring between the two valves, so that the two valves are subject to spring tension. There is another spring in the valve that acts on the lower part of the throttle valve. Also gives the throttle valve an upward tension.
