According to the present invention, disclosed is a check valve for a brake system. According to one aspect of the present invention, provided is a check valve for an integrated electric brake system including a hydraulic block in which a master cylinder is installed and in which a plurality of fluid passages and valves for regulating braking hydraulic pressure are provided, and a hydraulic pressure generating device coupled to the hydraulic block to generate a hydraulic pressure in accordance with the pressure of the brake pedal to supply the hydraulic pressure to a wheel cylinder. The check valve for an integrated electric brake system includes a valve housing installed in a bore of the hydraulic block and having a through-hole formed therein to form an oil passage having an orifice; an opening/closing member provided in the valve housing to open/close the orifice; and a cap fittingly coupled into the through-hole to prevent oil in the valve housing from leaking to the outside, wherein the valve housing is screwed to a bore to be detachably attached to the hydraulic block.

    본 발명의 브레이크 시스템용 체크밸브가 개시된다. 본 발명의 일 측면에 따르면, 마스터실린더가 설치되며 내부에 제동유압의 조절을 위한 다수의 유로 및 밸브가 마련되는 유압블록과, 상기 유압블록에 결합되어 브레이크 페달의 답력에 따라 액압을 발생하여 휠 실린더로 액압을 공급하는 액압발생장치를 포함하는 통합형 전자식 브레이크 시스템용 체크밸브에 있어서, 상기 유압블록의 보어에 설치되며 내부에 오리피스를 갖는 오일통로를 형성하도록 관통공이 형성된 밸브하우징; 상기 밸브하우징 내에 마련되어 상기 오리피스를 개폐하는 개폐부재; 및 상기 관통공에 압입 결합되어 상기 밸브하우징 내의 오일이 외부로 누유되는 것을 방지하는 캡;을 포함하고, 상기 밸브하우징은 상기 유압블록에 착탈가능하게 상기 보어에 나사결합되는 통합형 전자식 브레이크 시스템용 체크밸브가 제공될 수 있다.
