Abstract
Disclosed herein is a pressure damping device for a brake system which may reduce pressure pulsations generated by a piston pump. The pressure damping device is installed at a brake system having a hydraulic block provided with a first hydraulic circuit to control transfer of fluid pressures generated at a first port of a master cylinder and discharged from a first pump, and a second hydraulic circuit to control transfer of fluid pressures generated by a second port of the master cylinder and discharged from a second pump. The hydraulic block is provided with a bore connecting the master cylinder with a discharge outlet of each of the pumps and formed between main oil channels. The pressure damping device is provided in the bore, has a changeable volume, and includes a stopper member and a damping member. The damping member includes a ring-shaped elastic member and a plate.
