How Does an Automotive Vacuum Pump Work?

[LunaLee]

Automotive vacuum pumps operate based on the principle of air intake during engine operation, creating a vacuum on one side of the booster. This generates a pressure differential compared to the normal air pressure on the other side, which is then utilized to enhance braking thrust. Additional relevant information is as follows: Introduction: The vacuum booster pump consists of a large-diameter chamber, primarily composed of components such as the pump body, rotor, slider, pump cover, gear, and sealing ring. Note: Inside, there is a diaphragm (or piston) with a central push rod, dividing the chamber into two parts—one connected to the atmosphere and the other linked to the engine intake manifold via a pipe.
