A hydraulic device having improved safety is disclosed. According to an embodiment of the present invention, the hydraulic device comprises: a cylinder in which a working fluid inlet and a working fluid outlet are formed; a rod coupled to the cylinder to slide, and pushed out from the cylinder by a working fluid flowing into the cylinder; and a valve opening the working fluid outlet when internal pressure of the cylinder is more than a predetermined value, and closing the working fluid outlet when internal pressure of the cylinder is less than the predetermined value.

    안전성이 향상된 유압장치가 개시된다. 본 발명의 실시예에 따른 유압장치는 작동유체 유입부와 작동유체 배출부가 형성된 실린더; 상기 실린더에 슬라이딩 가능하게 결합되고, 상기 실린더로 유입된 작동유체에 의해 상기 실린더에서 밀려 나오는 로드; 및 상기 실린더 내부 압력이 설정값 이상이면 상기 작동유체 배출부를 개방시키고 상기 실린더 내부 압력이 상기 설정값 미만이면 상기 작동유체 배출부를 폐쇄시키는 밸브를 포함한다.
