How Does a Vacuum Pump Work?

Model: (Various brands) Various

Video tutorial

Vacuum pumps are installed in vehicles that do not have sufficient vacuum. Diesel engines, on the other hand, are equipped with vacuum pumps as standard, as they do not have throttle valves to create a pressure difference.

In many vehicles, vacuum is used to enhance braking, but also to operate pneumatic devices such as exhaust gas recirculation valves, exhaust valves, secondary air valves, intake manifold circuits, and turbine and turbocharger controls. Vacuum pumps generate a negative pressure of approximately 0.7 to 0.9 bar.
