vacuümservo
A vacuum servo is a type of hydraulic brake booster that uses engine vacuum to assist the driver's effort in applying the brakes. It is a component within the braking system of many vehicles. The vacuum servo consists of a housing divided into two chambers by a diaphragm. One chamber is connected to engine vacuum, while the other is open to atmospheric pressure. When the brake pedal is pressed, it operates a valve that allows either vacuum or atmospheric pressure to act on one side of the diaphragm, while the other side is exposed to the opposite pressure. This pressure difference creates a force that multiplies the driver's input, making it easier to apply sufficient braking force. The vacuum servo significantly reduces the physical effort required by the driver to operate the brakes, especially during hard braking situations. It is a common and important safety feature in automobiles.
