Clutch booster pump

Clutch booster pump is used for vehicle braking system

The working principle of the clutch vacuum booster pump is to utilize the principle of inhaling air when the engine is working, so that a vacuum is generated on one side of the booster and normal air pressure on the other side, thus generating a pressure difference, which in turn strengthens the braking thrust. Under normal conditions, the check valve at the position where the vacuum hose is connected to the vacuum booster is in an open state, connecting the vacuum air chamber and the application air chamber diaphragm, which are isolated from the outside world and connected to the atmosphere through two valve devices. When the brake pedal is depressed, the vacuum valve is closed under the action of the push rod, and the air valve at the other end is opened, which will lead to an imbalance of air pressure in the chamber, and when the air enters, the diaphragm will be pulled toward the end of the brake master cylinder under the action of the negative pressure, and the push rod of the brake master cylinder will also be driven, so as to realize the function of amplifying the force of the leg.
