Description

오일소모 저감 위한 밸브기구Valve mechanism to reduce oil consumption

본 고안은 오일소모 저감 위한 밸브기구에 관한 것으로, 보다 상세하게는 외주면에 고무와 오일 흡수용 필터가 형성되고 내주면에 스냅링이 삽입된 오일소모 방지링을 밸브의 요부홈에 장착하므로서 밸브의 상·하 이동시에 부압에 의해 연소실로 오일이 유입되는 것을 방지할 수 있는 오일소모 저감위한 밸브기구에 관한 것이다.The present invention relates to a valve mechanism for reducing oil consumption. More specifically, a rubber and oil absorption filter is formed on an outer circumference and an oil consumption prevention ring having a snap ring inserted into an inner circumference thereof is mounted on a recess of the valve. It relates to a valve mechanism for reducing oil consumption that can prevent oil from flowing into the combustion chamber by the negative pressure during the movement.

일반적으로 자동차 엔진 오일은 요소 각 부위의 윤활이나 냉각, 청소, 방청 및 연소실에서의 가스누출 방지를 위해 사용되고 있으며, 오일의 약 60%는 피스톤과 실린더의 틈새를 통해 연소실로 유입되어 없어지고 약 30%는 각 밸브를 통해 연소실로 유입되어 유실되게 된다.In general, automotive engine oil is used for lubrication, cooling, cleaning, rust prevention and gas leakage in the combustion chamber of each element, and about 60% of the oil flows into the combustion chamber through the gap between the piston and the cylinder and is lost. % Is lost through each valve into the combustion chamber.

자동차 엔진의 연소실에는 흡입되는 혼합기 및 배출되는 연소가스를 단속하는 흡·배기밸브가 각각 구비되어 있으며, 이러한 흡·배기밸브는 밸브 기구에 의해 피스톤의 행정에 맞추어 개폐되도록 되어 있다.A combustion chamber of an automobile engine is provided with an intake / exhaust valve for intermitting a mixer to be sucked and a combustion gas discharged, and the intake / exhaust valve is opened and closed in accordance with the stroke of the piston by a valve mechanism.

종래 밸브기구의 구성을 보면 도 1 및 도 2에 도시된 바와 같이, 먼저 실린더 헤드(110)에 흡기포트(111) 및 배기포트(112)를 폐쇄시키는 밸브(120)가 각각 설치되어 있고, 로커암 축(131)을 중심으로 유동하면서 상기 밸브(120)를 하부로 밀어 흡·배기포트(111)(112)를 개방시키는 로커암(130)이 밸브(120)의 상단에 각각 설치되어 있으며, 각 로커암(130)은 캠축(132)의 회전에 의해 유동되도록 되어 있다.1 and 2, a valve 120 for closing the intake port 111 and the exhaust port 112 is provided in the cylinder head 110, respectively. Rocker arms 130 for opening the intake / exhaust ports 111 and 112 by pushing the valve 120 downward while flowing about the arm shaft 131 are respectively installed at the upper end of the valve 120. Each rocker arm 130 is made to flow by the rotation of the camshaft 132.

상기 밸브(120)의 상단에 설치된 스프링 리테이너(122)와 실린더 헤드(110) 간에는 밸브(120)를 탄력적으로 폐쇄시키도록 하는 밸브 스프링(121)이 설치되어 있고, 그 밸브 스프링(121)과 실린더 헤드(110)의 접촉부위에는 밸브 스프링(121)을 지지하는 스프링 시트(125)가 설치되어 있으며, 상기 실린더 헤드(110)에 접촉되는 밸브 스템(120a)의 외주면에는 밸브 가이드(123)이 설치되어 있다.Between the spring retainer 122 and the cylinder head 110 provided at the upper end of the valve 120 is provided with a valve spring 121 to elastically close the valve 120, the valve spring 121 and the cylinder A spring seat 125 for supporting the valve spring 121 is installed at a contact portion of the head 110, and a valve guide 123 is installed at an outer circumferential surface of the valve stem 120a contacting the cylinder head 110. It is.

이와 같은 종래 엔진 밸브기구는 피스톤의 왕복 운동함에 따라 변환되는 크랭크 축의 회전운동이 캠축(132)에 전달된다. 이에 따라, 피스톤의 흡·배기 행정시 로커암(130)은 캠축(132)에 의해 로커암 축(131)을 중심으로 밸브(120)를 하부로 밀게 된다. 이때, 밸브(120)는 밸브 스프링(121)을 압축시키면서 흡기포트(111) 또는 배기포트(112)를 개방시키고, 계속 캠축(132)이 회전함에 따라 압축되었던 밸브 스프링(121)에 의해 탄력적으로 다시 흡기포트(111) 또는 배기포트(112)를 폐쇄시킨다.In such a conventional engine valve mechanism, the rotational movement of the crankshaft, which is converted as the piston reciprocates, is transmitted to the camshaft 132. Accordingly, the rocker arm 130 pushes the valve 120 downward about the rocker arm shaft 131 by the cam shaft 132 during the intake and exhaust stroke of the piston. At this time, the valve 120 opens the intake port 111 or the exhaust port 112 while compressing the valve spring 121, and is resiliently elastically by the valve spring 121 that has been compressed as the camshaft 132 rotates. Again, the intake port 111 or the exhaust port 112 is closed.

그러나, 이와 같은 구성의 밸브 기구는 밸브와 밸브 가이드 사이를 통하여 오일이 연소실로 유입되므로서 블로바이 가스와 섞여 흐르면서 엔진내에 카본을 퇴적시키며 연소실을 오염시키게 되어 엔진의 효율이 떨어지고 오일 소모가 많게 되는 문제가 발생하게 되었다.However, the valve mechanism having such a configuration causes oil to flow into the combustion chamber between the valve and the valve guide, and flows with the blow-by gas to deposit carbon in the engine and contaminate the combustion chamber, resulting in low engine efficiency and high oil consumption. Problems have arisen.

상기한 바와 같은 문제점을 해결하기 위한 본 고안은 외주면에 고무와 오일 흡수용 필터가 형성되고 내주면에 스냅링이 삽입된 오일소모 방지링을 밸브의 요부홈에 장착함으로서 밸브의 상·하 이동시에 부압에 의해 연소실로 오일이 유입되는 것을 방지하여 엔진의 효율을 높이고 오일 소모를 저감시키는데 그 목적이 있다.The present invention for solving the problems as described above is provided with a negative pressure during the up and down movement of the valve by mounting the oil consumption prevention ring is formed in the main groove of the valve, the rubber and oil absorption filter is formed on the outer peripheral surface and the snap ring is inserted into the inner peripheral surface The purpose of this is to prevent oil from flowing into the combustion chamber, thereby improving engine efficiency and reducing oil consumption.

상기한 목적을 달성하기 위한 본 고안은 밸브 스프링에 의해 밸브가 탄력적으로 실린더 헤드에 설치되고 캠축을 회전시킴에 따라 밸브가 밸브 스프링을 압축하면서 흡기포트 및 배기포트를 개폐시키는 엔진 밸브기구에 있어서, 밸브의 요부홈에 고무와 오일 흡수용필터가 외주면에 형성되고 스냅링이 내주면에 삽입된 오일소모 방지링이 장착되어 밸브 가이드의 내주면을 이동할 수 있는 오일소모 저감을 위한 밸브기구를 제공함에 있다.The present invention for achieving the above object is in the engine valve mechanism for opening and closing the intake port and exhaust port while the valve compresses the valve spring as the valve is elastically installed in the cylinder head by the valve spring and rotates the camshaft, Rubber and oil absorption filter is formed on the outer circumferential groove of the valve is provided on the outer peripheral surface and the oil consumption prevention ring is inserted into the inner peripheral surface of the snap ring is provided to provide a valve mechanism for reducing the oil consumption that can move the inner peripheral surface of the valve guide.

본 고안 오일소모 저감을 위한 밸브기구의 주요 구성을 보면 밸브 스프링에 의해 탄력적으로 설치되어 있으며 요부홈에 오일소모 방지링이 장착된 밸브와, 로커암축을 중심으로 밸브를 개폐하는 로커암과, 크랭크축의 동력에 의해 회전하면서 로커암을 움직이는 캠축으로 이루어져 있다.The main structure of the valve mechanism for reducing oil consumption of the present invention is a valve which is elastically installed by a valve spring and is equipped with an oil consumption preventing ring in the recessed groove, a rocker arm that opens and closes the valve around the rocker arm shaft, and a crank. It consists of a camshaft that moves the rocker arm while rotating by the power of the shaft.

좀 더 상세히 본 고안의 구성을 보면 도 3 및 도 4에 도시된 바와 같이, 밸브 스프링(21)에 의해 실린더 헤드(10)에 탄력적으로 설치된 밸브(20)는 밸브 가이드(23)의 내주면을 상·하로 이동하면서 흡·배기포트(11, 12)를 개폐하게 된다.3 and 4, the valve 20 elastically installed on the cylinder head 10 by the valve spring 21 may have an inner circumferential surface of the valve guide 23. • The inlet and exhaust ports 11 and 12 are opened and closed while moving downward.

즉, 밸브 스템(20a)이 밸브 가이드(23)의 내주면을 따라 상·하로 움직일때마다 밸브 페이스(20b)가 밸브 시트(27)와 접촉·분리되어 흡·배기포트(11, 12)를 개폐하게 된다.That is, whenever the valve stem 20a moves up and down along the inner circumferential surface of the valve guide 23, the valve face 20b contacts and separates from the valve seat 27 to open and close the intake / exhaust ports 11 and 12. Done.

특히, 밸브(20)의 요부홈(28)에 고무(41)와 오일 흡수용필터(45)가 외주면에 형성되고 스냅링(43)이 내주면에 삽입된 오일소모 방지링(40)이 장착되어 있어 밸브 가이드(23)의 내주면을 이동하게 된다.In particular, in the recessed groove 28 of the valve 20, a rubber 41 and an oil absorption filter 45 are formed on the outer circumferential surface, and the oil consumption prevention ring 40 in which the snap ring 43 is inserted into the inner circumferential surface is mounted. The inner circumferential surface of the valve guide 23 is moved.

이와 같이 구성된 본 고안의 작용 상태를 보면, 먼저 밸브(20)의 요부홈(28)에 장착된 오일소모 방지링(40)은 내주면에 삽입된 스냅링(43)에 의해 바깥으로 팽창하여 밸브 가이드(23)의 내부면과 밀착되어 접촉하게 된다.Looking at the operating state of the present invention configured as described above, first, the oil consumption preventing ring 40 mounted on the recess groove 28 of the valve 20 is expanded outward by the snap ring 43 inserted into the inner peripheral surface of the valve guide ( 23) is in close contact with the inner surface of the.

밸브(20)와 밸브 가이드(23) 사이에 형성된 오일은 밸브(20)가 상·하로 이동할 때에 서로 고체마찰이 이루어지지 않도록 윤활작용을 하게 되며, 특히 연소실의 부압에 의해 오일이 빨려 들어가는 것을 오일소모 방지링(40)에 의해 방지하게 된다.The oil formed between the valve 20 and the valve guide 23 is lubricated so that the solid friction does not occur when the valve 20 moves up and down. In particular, the oil is sucked in by the negative pressure of the combustion chamber. It is prevented by the exhaustion prevention ring 40.

따라서 본 고안은 밸브의 요입홉에 장착된 오일소모 방지링에 의해 밸브와 밸브 가이드 사이에 분포된 오일이 연소실로 유입되어 들어가는 것을 방지하여 오일소모를 저감하게 된다.Therefore, the present invention reduces the oil consumption by preventing the oil distributed between the valve and the valve guide from entering the combustion chamber by the oil consumption prevention ring mounted on the inlet hop of the valve.

이상에서 살펴본 바와 같이, 본 고안은 외주면에 고무와 오일 흡수용필터가 형성되고 내주면에 스냅링이 삽입된 오일소모 방지링을 밸브의 요부홈에 장착하므로서 밸브의 상·하 이동시에 부압에 의해 연소실로 오일이 유입되는 것을 방지하여 엔진 내부의 카본 퇴적으로 엔진 효율이 떨어지는 것을 방지하며 오일이 많이 소모되는 것을 방지할 수 있는 효과가 있다.As described above, the present invention installs an oil consumption prevention ring having a rubber and oil absorption filter formed on the outer circumferential surface and a snap ring inserted into the inner circumferential surface of the valve groove, so that the valve moves to the combustion chamber by negative pressure during the up and down movement of the valve. By preventing oil from flowing in, it is possible to prevent the engine efficiency from dropping by carbon deposition inside the engine and to prevent the oil from being consumed much.

본 고안은 상기 실시예에 한정되지 않고 본 고안의 기술적 요지를 벗어나지 않는 범위내에서 당해 기술분야의 통상의 지식을 가진 자에 의해 다양하게 변형 실시될 수 있다.The present invention is not limited to the above embodiments and can be variously modified and implemented by those skilled in the art without departing from the technical gist of the present invention.
