1. A high pressure accumulator of a brake system disposed on a modulator block to reduce pressure pulsation of brake oil pressed by driving of a pump and pumped, the high pressure accumulator comprising:
a closing member that closes one end of a bore having one opened end and is in communication with an inport through which the brake oil is introduced and an outport through which the brake oil is discharged; and a damping housing that is installed in the bore and has a damping chamber formed therein in communication with the inport and the outport, wherein an orifice part is formed integrally with the damping housing in a portion in which the brake oil is discharged through the outport, and a damping member is installed in the damping housing and partitions the damping chamber into a plurality of layers so that the partitioned plurality of layers are in communication with each other, and the damping member comprises a body part having one opened side to partition the damping chamber into a plurality of layers and a connection hole formed in a bottom surface of the body part in communication with the adjacent damping chamber partitioned by the body part, and an inclined part is formed on the bottom surface of the body part so that the brake oil easily flows into the adjacent damping chamber, and the connection hole is formed in distal ends of the inclined part. |
