ABSTRACT:
The present invention is directed to providing an accumulator for pulsation absorption on a feeding passage between a hydraulic pressure generating device and hydraulic pressure booster equipment, and to provide a restriction on a section of the feeding passage between the accumulator and the hydraulic pressure generating device. As the result, the pulsation caused by a pump is reduced by the restriction, and the pulsation thus reduced is absorbed by the accumulator. Therefore, pulsation is effectively decreased by the restriction and the accumulator, and the pulsation transmitted to the hydraulic pressure booster equipment is quite small.
