The present invention relates to a pump device for an electronic control brake system, which comprises: a housing unit; a motor cam unit mounted in the housing unit; a piston unit embedded in the housing unit, and moved by friction with the motor cam unit; a compression unit coupled to an end portion of the piston unit to guide oil, and absorbing a shock of the piston unit; an inflow unit embedded in the housing unit, wherein the compression unit is inserted thereinto, and oil supplied through the compression unit is stored; a sealing unit arranged between the inflow unit and the compression unit to prevent an oil leak; and a discharge unit embedded in the housing unit, and selectively allowing discharge of oil in accordance with pressure of the oil stored in the inflow unit. Therefore, a shock in an operating process is relieved, and damage to a sealing portion by movement can be restricted.

    본 발명은 전자제어식 브레이크 시스템용 펌프장치에 관한 것으로, 하우징부와, 하우징부에 장착되는 모터캠부와, 하우징부에 내장되고 모터캠부와의 마찰에 의해 이동되는 피스톤부와, 피스톤부의 단부와 결합되어 오일을 안내하고 피스톤부의 충격을 흡수하는 압박부와, 하우징부에 내장되고 압박부가 삽입되며 압박부를 통해 공급되는 오일을 저장하는 유입부와, 유입부와 압박부 사이에 배치되어 누유를 방지하는 밀봉부와, 하우징부에 내장되고 유입부에 저장된 오일의 압력에 따라 오일의 토출을 선택적으로 허용하는 배출부를 포함하여, 작동과정에서 충격을 완화하고 유동에 의한 밀봉부위의 손상을 억제할 수 있다.
