즉, 상기 제3 영역(c), 상기 제2 영역(b), 상기 제1 영역(a)의 순으로 내부 압력이 높게 형성된다.That is, the internal pressure is formed in the order of the third region (c), the second region (b), and the first region (a).

이하에서는 도 2를 참조하여, 본 발명에 따른 범퍼구간이 구비된 압력 전달 실린더의 구동 원리를 설명한다.Hereinafter, a driving principle of a pressure transmission cylinder equipped with a bumper section according to the present invention will be described with reference to FIG. 2.
비압축성 유체는 유체 유입구(110a)를 통해 상기 실린더 본체의 제3 영역(c)으로 유입된다.The incompressible fluid is introduced into the third region (c) of the cylinder body through the fluid inlet (110a).
이때, 상기 유체 유입구(110a)는 상기 실린더 본체(110)의 상측면, 하측면, 제1 캡(120) 또는 제2 캡(130)에 형성되어, 상기 실린더 본체의 제3 영역(c)과 연통되도록 설치될 수 있다. At this time, the fluid inlet (110a) is formed on the upper side, the lower side, the first cap 120 or the second cap 130 of the cylinder body 110, and the third area (c) of the cylinder body It can be installed to communicate.
이후, 상기 제3 영역(c)으로 유입된 유체는 상기 제2 피스톤(160)의 타측면을 가압하여 상기 제1 피스톤(140), 상기 제2 피스톤(160), 상기 제1 로드(150), 상기 제2 로드(170)가 함께 순방향(제1 캡 방향)으로 이동된다.Thereafter, the fluid flowing into the third region (c) presses the other side of the second piston 160 to cause the first piston 140, the second piston 160, and the first rod 150 to flow. , The second rod 170 is moved in the forward direction (first cap direction) together.
이는, 상기 제1 영역(a)의 압력이 상기 제2 영역(b), 상기 제3 영역(c)의 압력에 비해 낮으므로, 상기 제3 영역(c)으로 유입되는 비압축성 유체의 체적만큼 상기 제1 영역(a)의 체적이 점차적으로 감소되면서, 상기 제1 피스톤(140), 상기 제2 피스톤(160), 상기 제1 로드(150), 상기 제2 로드(170)가 함께 이동되는 것이다.This is because the pressure of the first region (a) is lower than the pressure of the second region (b) and the third region (c), so that the volume of the incompressible fluid flowing into the third region (c) is As the volume of the first region (a) gradually decreases, the first piston 140, the second piston 160, the first rod 150, and the second rod 170 move together. .
상기 제1 피스톤(140)이 상기 제1 캡(120)에 면접된 이후에 상기 제3 영역(c)으로 비압축성 유체가 유입될 때에는, 상기 제2 피스톤(160) 및 상기 제2 로드(170)가 순방향으로 이동된다.When the incompressible fluid flows into the third region (c) after the first piston 140 is interviewed to the first cap 120, the second piston 160 and the second rod 170 Is moved in the forward direction.
이는, 상기 제1 피스톤(140)의 경우 상기 제1 캡(120)에 면접되므로 더 이상 순방향으로 이동되지 않으며, 상기 제2 영역(b)의 압력은 상기 제3 영역(c)의 압력에 비해 낮으므로, 상기 제2 영역(b)의 체적이 점차적으로 감소되면서, 상기 제2 피스톤(160) 및 상기 제2 로드(170)가 순방향으로 이동되는 것이다.This is, in the case of the first piston 140, since it is interviewed to the first cap 120, it is no longer moved in the forward direction, and the pressure in the second region (b) is compared to the pressure in the third region (c). Since it is low, the volume of the second region (b) is gradually reduced, and the second piston 160 and the second rod 170 are moved in the forward direction.
즉, 상기 제2 영역(b)은 추가적으로 유입되는 비압축성 유체의 완충 영역으로 기능하므로, 유입되는 비압축성 유체의 허용범위를 증대시킬 수 있는 이점을 지닌다.That is, since the second region (b) additionally functions as a buffer region of the incompressible fluid being introduced, it has an advantage of increasing the allowable range of the incompressible fluid being introduced.
