High Performance Vacuum Pump For Volvo Brake System With OE Number 31370519

OE number: 31370519

Applicable vehicle type: For Volvo

The vacuum pump is installed on the engine and driven by the crankshaft. It creates vacuum through the piston's movement in the pump body. When the engine runs, the piston's downward movement expands the pump chamber, reducing pressure to create vacuum.

This vacuum transfers via lines to the brake booster (typically a vacuum booster), which uses vacuum to increase brake system pressure, reducing required pedal force.

The vacuum booster utilizes vacuum force to assist master cylinder piston movement when braking, generating sufficient force with less pedal pressure. Upon pedal release, the system returns to its initial state.

In intelligent braking systems, the electronic vacuum pump (EVP) operates independently of engine status, providing reliable vacuum assistance during engine stop or low-speed operation for enhanced braking flexibility and safety.
