본 발명은 일단부는 제1 유압 회로와 연결되고, 타단부는 제2 유압 회로와 연결되는 블록 하우징; 상기 블록 하우징에 내장되고, 상기 제1 유압 회로로 유입되는 작동 유체에 의한 압력을 완충하면서 상기 제2 유압 회로의 압력 상승을 보조하며, 형상 변형을 허용하는 댐퍼; 및 상기 블록 하우징에 내장되고, 상기 제1 유압 회로와 상기 댐퍼 및 상기 제2 유압 회로와 상기 댐퍼 사이에 각각 배치되며, 상기 제1, 2 유압 회로로부터 유입되는 상기 작동 유체의 점성을 감소시키는 점성감쇠 유닛;을 포함하여, 비교적 간단한 구성으로 압력 맥동을 저감하고 충격 완화 및 압력 상승이 안정적이면서도 동시에 이루어지도록 하는 유압 피스톤 펌프의 맥동 저감장치에 관한 것이다.

    The present invention relates to a pulsation reduction apparatus of a hydraulic piston pump, comprising: a block housing that has one end connected to the first hydraulic circuit and the other end connected to the second hydraulic circuit; a damper that is embedded in the block housing, absorbs pressure resulting from working fluid introduced to the first hydraulic circuit, assists with pressure increase of the second hydraulic circuit, and allows shape deformation; and viscosity damping units that are embedded in the block housing, are arranged between the first hydraulic circuit and the damper and between the second hydraulic circuit and the damper, and reduce viscosity of the working fluid introduced from the first and second hydraulic circuits, thereby reducing pressure pulsation and stably performing shock absorption and pressure increase at the same time with a relatively simple configuration.
