Disclosed is a brake system. The brake system includes a pulsation attenuation device configured to attenuate pressure pulsation of brake oil discharged from a pump, wherein the pulsation attenuation device includes a first damping device, wherein the first damping device includes: a first damping member inserted into a first bore in communication with an in-port through which brake oil is introduced and an out-port through which brake oil is discharged and having a hollow formed therein; a second damping member inserted into the hollow to form a damping space between the second damping member and an inner circumferential surface of the first damping member; and a sealing member coupled to the first damping member and configured to seal the first bore, wherein the damping space is formed by a plurality of grooves formed in the hollow.

Brake system

Disclosed herein is a pulsation damping device of a hydraulic brake system. The pulsation damping device of a hydraulic brake system which attenuates a pressure pulsation of brake oil discharged from a pump, the device comprises a damping portion installed to be inserted into a bore in communication with an inport into which the brake oil flows and an outport through which the brake oil is discharged, and a cap coupled to one end of the bore to block the one end, wherein a flow path is formed on an outer circumferential surface of the damping portion to guide the brake oil introduced into the inport to be discharged through the outport, and the flow path is formed in a longitudinal direction of the damping portion to be continuously connected from the inport to the outport.

Pulsation damping device of hydraulic brake system

Disclosed herein is a pulsation damping device of a hydraulic brake system. The pulsation damping device of a hydraulic brake system which attenuates a pressure pulsation of brake oil discharged from a pump comprise a sleeve inserted into a bore which communicates with an inport into which the brake oil is introduced and an outport through which the brake oil is discharged, wherein one end of the sleeve is open and the other end is closed, a damping member accommodated in the sleeve and hollowed to form a damping space therein, and a stopper member configured to block one open end of the bore and coupled to an opening of the sleeve.
