Air booster of wheel loader parts

Brake Booster is A device that converts low pressure to high pressure. It uses air pressure as a power to push the piston in the oil tank of Guoli. The piston in the cylinder moves through the transmission device of the push rod, thereby increasing the pressure of the brake fluid, and then transmitting it to the brake caliper to achieve the braking effect. The air pressure of the loader is 0.8MPA, but the afterburner is converted to 4MPA
