ABSTRACT:
A brake device has at least one wheel cylinder operable by the pressure of a working liquid. A reservoir stores the working liquid discharged from the at least one wheel cylinder during the operation of an anti-lock braking function. A pump serves to transfer the working liquid from the reservoir. An outlet valve is disposed on the discharge side of the pump. A master cylinder receives the working liquid delivered from the pump via the outlet valve. A pulsation reducing device is disposed on a downstream side of the outlet valve between the pump and the master cylinder. The pulsation reducing device controls the operation speed of the outlet valve in order to reduce possible pulsations produced in the working liquid discharged from the pump.
