Description
본 고안은 유입 봉입형 자동조절 밸브에 관한 것으로, 기존의 자동래시 및 유로를 삭제시켜 레이아웃(LAYOUT) 및 밸브의 성능을 향상 시키도록 하는 것이다.The present invention relates to an inlet sealed type self-regulating valve to improve the layout (LAYOUT) and the performance of the valve by eliminating the existing automatic lash and flow path.
알려진 바와 같이 밸브스템(VALVE STEM)은 밸브 가이드에 끼워져 밸브운동을 보호하며 밸브헤드의 열은 가이드를 통하여 냉각시키도록 구성하고 있고, 밸브의 간극을 유지하기 위하여 오토래시 및 유로를 형성하도록 구성하고 있어 그 구성이 복잡하고 노이즈 증가 및 조정이 필요하는등 문제점이 지적되고 있다.As is known, the valve stem is fitted to the valve guide to protect the valve movement, and the heat of the valve head is configured to cool through the guide, and to form an autolash and a flow path to maintain the valve gap. The problem is pointed out that the configuration is complicated and noise increase and adjustment are necessary.
본 고안은 상기와 같은 문제점을 해소하기 위하여 안출한 것으로 밸브스템 끝단부(로커암) 접촉부에 유입 봉입형 자동조절 장치를 설치하여 밸브의 간극을 항상 “0”으로 유지하도록 하기 위한 것이다.The present invention has been made to solve the above problems to install the inlet enclosed type automatic adjustment device in the valve stem end (rocker arm) contact portion to maintain the valve clearance at "0" at all times.
제1도는 본 고안의 설치상태를 보인 단면도.1 is a cross-sectional view showing the installation state of the present invention.

이와 같은 본 고안을 제1도에 의하여 구체적으로 설명하면 다음과 같다.The present invention as described in detail with reference to FIG. 1 as follows.
밸브스템 끝단부(7)에 상부가 개방된 오일 고압실(9)을 형성한다. 이같은 오일 고압실(9)의 상단에는 밸브헤드(1)를 슬라이드 이동 가능하도록 설치하되, 상기 밸브헤드(1)의 외측면에 밀폐용 링(10)이 결합되어 상기 오일 고압실(9) 내의 오일이 외부로 누출되는 것을 방지하며, 이러한 밸브헤드(1)의 하방에 유입통로(3)를 갖는 피스톤(2)이 일체로 형성된다. 또한 상기 밸브헤드(1)의 상면에 한 쌍의 에어홀(1a)이 천공되며, 그 저면에 상기 에어홀(1a)과 연통되는 튜브(1b)가 각각 설치되는 것으로, 상기 튜브(1b)는 평상시에 에어를 채운 상태를 유지하는 것이다. 그리고, 상기 피스톤(2)의 유입통로(3) 하방에 체크 볼 밸브(4)가 설치되며, 상기 피스톤(2)의 하면과 상기 오일 고압실(9)의 바닥면 사이에 리턴스프링(5)이 탄설된다. 도면중 6은 로커암, 8은 체크 볼 밸브의 스프링이다.An oil high pressure chamber 9 having an open upper portion is formed at the end of the valve stem 7. The upper end of the oil high-pressure chamber 9 is installed to slide the valve head 1, the sealing ring 10 is coupled to the outer surface of the valve head 1 in the oil high-pressure chamber 9 The oil is prevented from leaking to the outside, and a piston 2 having an inflow passage 3 is formed integrally under the valve head 1. In addition, a pair of air holes 1a are punctured on the upper surface of the valve head 1, and tubes 1b communicating with the air holes 1a are respectively installed on the bottom of the valve head 1, and the tube 1b is It is to keep the air in normal condition. Then, a check ball valve 4 is installed below the inflow passage 3 of the piston 2, and a return spring 5 is disposed between the bottom surface of the piston 2 and the bottom surface of the oil high pressure chamber 9. This is a snowfall. 6 is a rocker arm, 8 is a spring of a check ball valve.
이와 같이 구성된 본 고안은 캠 노즈 상태일 경우, 상기 밸브헤드(1)를 누르는 힘에 의해 밸브헤드(1)가 하향으로 슬라이드 이동되려 하면서 오일 고압실(9)내의 오일의 튜브(1b)를 압박하게 되고, 이에 따라 상기 튜브(1b) 내의 에어가 에어홀(1a)을 통해 외부로 배출되면서 수축하게 된다. 이같은 튜브(1b)의 수축에 따른 체적의 축소만큼 밸브헤드(1)는 하방으로 슬라이드 이동되며, 이때 피스톤(2)도 동시에 하방으로 이동하게 되는 한편, 상기 피스톤(2)에 형성된 유입통로(3)는 체크 볼 밸브(4)에 의해 차단된 상태를 유지하게 된다. 그리고 상기 피스톤(2)의 이동에 따라 리턴스프링(5)은 압축되게 되고, 상기 리턴스프링(5)이 일정 한계까지 압축되면 더 이상 압축되지 않으면서 상기 밸브헤드(1)의 하향이 멈춰지게 되며, 이 같은 밸브 헤드(1)의 고정과 동시에 밸브전체가 일체로 개폐동작을 수행하게 되는 것이다. 그리고 캠 베이스 서클 상태일 경우, 상기 리턴스프링(5)에 의해 상기 밸브헤드(1)가 로커암(6) 측으로 상향 이동하여 밸브의 간극을 “0”으로 유지하게 되며, 이때 오일 고압실(9) 내의 압력변화에 의해 상기 튜브(1b)의 내측으로 외부 공기가 유입되어 튜브(1b)는 팽창된 상태를 유지하게 되고, 상기 체크 볼 밸브(4)는 상기 유입통로(3)를 오픈시킨 상태이다.The present invention configured as described above presses the tube 1b of oil in the oil high pressure chamber 9 while the valve head 1 is slid downward by the pressing force of the valve head 1 in the cam nose state. Accordingly, the air in the tube 1b is contracted while being discharged to the outside through the air hole 1a. As the volume of the tube 1b shrinks, the valve head 1 slides downward, and at the same time, the piston 2 simultaneously moves downward, while the inflow passage 3 formed in the piston 2 is moved. ) Will remain blocked by the check ball valve (4). The return spring 5 is compressed according to the movement of the piston 2, and when the return spring 5 is compressed to a certain limit, the valve head 1 stops downward without being compressed anymore. At the same time as the valve head 1 is fixed, the entire valve is integrally opened and closed. In the cam base circle state, the valve head 1 is moved upward by the return spring 5 to the rocker arm 6 to maintain the clearance of the valve at "0", where the oil high pressure chamber 9 External air flows into the inside of the tube 1b due to the change in pressure within the tube 1b, thereby maintaining the expanded state of the tube 1b, and the check ball valve 4 opens the inlet passage 3. to be.
이상과 같이 본 고안은 밸브간극을 항시 “0”으로 유지케 함으로써 노이즈 감소 및 밸브조정이 불필요하고 기존의 오토래시 및 유로가 필요없어 레이아웃 및 밸브성능을 크게 향상시킬 수 있게 되는 것이다.As described above, the present invention maintains the valve clearance at “0” at all times, thereby reducing noise and adjusting valves, and eliminating the need for conventional auto-lash and flow paths, thereby greatly improving layout and valve performance.
