6.1.2. Vacuum amplifier of brakes

The vacuum amplifier of brakes reduces effort to a brake pedal, facilitating driving. In the vacuum amplifier the diaphragm from which both parties at a normal operating mode depression is created is used. When braking on the one hand diaphragms air, forming atmospheric pressure moves. At the expense of a difference of the pressure transferred through a diaphragm, the pusher moves towards depression (vacuum), providing auxiliary force for braking. At an otpuskaniye of a pedal of a brake air is pumped out from a cavity of the amplifier via the control valve, creating depression.
