Principle of working principle of brake vacuum pump: the brake booster pump uses the principle of breathing in air when the engine is working to create a vacuum on one side of the booster. The pressure difference is generated relative to the normal air pressure on the other side, and the pressure difference is used to strengthen the braking thrust. Even if there is only a small pressure difference between the two sides of the diaphragm, due to the large area of the diaphragm, a large amount of thrust can be generated to push the diaphragm towards the lower pressure side. Under working condition, the push rod return spring brake pedal in the initial position, at this point, the vacuum tube connected to the vacuum booster position of check valve is in open state, from inside the booster, the diaphragm will be divided into its true air chamber air chamber, and the application can be connected between the two, both isolated in most of the time, The chamber is connected to the atmosphere by two valves. structure The brake booster pump is a large diameter vacuum chamber, inside which there is a diaphragm (or piston) equipped with a push rod in the middle, which divides the chamber into two parts. One part is communicated with the atmosphere, and the other part is connected with the engine intake pipe through a pipe. So, when the engine shuts down, because there is no intake vacuum, there is no help, and braking requires a lot of manpower. It should be noted that many novices believe that when the engine flameout, there is no braking, which is not true
