Pierburg Vacuum pump 7.24807.41.0

A vacuum pump in a car is an essential component of the vehicle's braking system. It works by creating suction and generating a vacuum that helps to boost the power of the brakes. The pump is typically driven by the engine's belt and is connected to the brake booster. When the driver presses the brake pedal, a valve in the booster opens, allowing the vacuum created by the pump to assist in applying pressure to the brake fluid. This vacuum pressure enables the brake system to work more efficiently and provide better braking performance.

In addition to its role in the braking system, a vacuum pump in a car may also be responsible for other functions such as operating the HVAC (heating, ventilation, and air conditioning) system and controlling the engine's emissions. When it comes to the HVAC system, the vacuum pump creates suction to regulate air flow and adjust temperature settings. It also helps to control the ventilation system by opening and closing various vents. Moreover, the vacuum pump is crucial for maintaining the proper functioning of emission control systems, such as the EGR (exhaust gas recirculation) system, which reduces harmful emissions by recirculating a portion of the exhaust gases back into the engine for combustion.
