The present invention relates to a pulsation reduction device for a hydraulic piston pump comprising: a block housing of which one end part is connected with a first hydraulic circuit and the other end part is connected with a second hydraulic circuit; a damper embedded in the block housing and buffering pressure due to a working fluid introduced to the first hydraulic circuit and assisting pressure rise of the second hydraulic circuit and allowing shape deformation; and a viscosity reduction unit embedded in the block housing and disposed between the first hydraulic circuit and the damper and the second hydraulic circuit and the damper and reducing viscosity of the working fluid introduced from the first and the second hydraulic circuit. Therefore, the present invention reduces pulsation of pressure and relieves an impact and stably raise pressure with a relatively simple configuration.

    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.
