Description
본 고안은 흡배기 포트를 개폐하는 밸브의 오일소모 저감구조에 관한 것이다.The present invention relates to an oil consumption reduction structure of the valve for opening and closing the intake and exhaust ports.
흡배기 밸브(10)는 도 2 에 도시하는 것과 같이 실린더헤드(11)에 설치되어 흡배기 포트(12)를 개폐하여 엔진에 흡기를 도입하거나 연소된 가스를 외부로 배출하게 된다.As shown in FIG. 2, the intake and exhaust valve 10 is installed in the cylinder head 11 to open and close the intake and exhaust port 12 so as to introduce intake into the engine or discharge the burned gas to the outside.
그런데 밸브(10)는 로커암(13) 또는 회전하는 캠에 의해 고속으로 왕복 직선 운동을 하게 되므로 실린더 헤드(11)와의 사이에 밸브(10)의 직선운동을 안내하기 위한 밸브가이드(14)에 끼워져 슬라이딩 운동하고 있다.However, since the valve 10 reciprocates linearly at a high speed by the rocker arm 13 or the rotating cam, the valve guide 14 guides the linear movement of the valve 10 between the cylinder head 11. It is fitted and is sliding.
그러나 밸브 트레인 기구는 고속 작동하므로 마찰 부위의 윤활 및 냉각을 위해 엔진오일이 공급되고 있기 때문에 밸브(10)와 밸브가이드(14) 사이의 틈새를 통해 오일이 연소실로 침투하여 엔진오일의 과도한 소모를 가져오고 배기가스를 악화시키게 되는 문제점이 있었다.However, since the valve train mechanism operates at a high speed, the engine oil is supplied for the lubrication and cooling of the friction part. There was a problem of bringing and worsening the exhaust gas.
이에 본 고안은 상기한 문제점을 감안하여 제안된 것으로써 그의 목적으로 하는 바는 밸브가이드와의 틈새를 통한 엔진 오일의 연소실 침투를 방지하는 밸브의 오일 소모 저감구조를 제공하는데 있다.The present invention has been proposed in view of the above problems, and its object is to provide a structure for reducing oil consumption of a valve which prevents combustion chamber penetration of engine oil through a gap with the valve guide.

이하 본 고안의 구성과 작용을 첨부한 도면을 참조하여 설명한다.Hereinafter, with reference to the accompanying drawings the configuration and operation of the present invention.
도 1 은 본 고안에 의한 밸브의 오일소모 저감구조의 요부구성도로서 도면에 있어 부호 1은 흡배기 밸브의 밸브스템을 나타낸다.1 is a principal part configuration diagram of an oil consumption reduction structure of a valve according to the present invention, in which 1 is a valve stem of an intake and exhaust valve.
상기 밸브스템(1)은 원통형의 밸브가이드(2)의 안내를 따라 슬라이딩 왕복 작동하며 그의 외주면에는 복수개의 링 그루우브(3)가 형성되어 있다.The valve stem 1 is reciprocated sliding along the guide of the cylindrical valve guide 2 and a plurality of ring grooves 3 are formed on the outer circumferential surface thereof.
상기 각 링 그루우브(3)에는 오일링(4)이 밸브가이드(2)의 내벽면(5)에 탄력적으로 말착하도록 삽입되어 있다.An oil ring 4 is inserted into each of the ring grooves 3 so as to elastically adhere to the inner wall surface 5 of the valve guide 2.
상기 오일링(4)의 내벽면(5)과의 밀착부는 마찰의 감소를 위해 라운딩 형상(Barrel face)으로 되어 있으며 이들 구성은 마치 피스톤 링과 피스톤 링 그루우브와 같은 구성으로 같은 역할을 하게 된다.The close contact portion with the inner wall surface 5 of the oil ring 4 has a rounded face to reduce friction, and these components play the same role as the piston ring and the piston ring groove. .
이에 따라 엔진이 구동되어 엔진 부압이 작용할 때 밸브스템(1)과 밸브가이드(2)의 틈새를 통해 연소실로 흡입되는 엔진오일은 오일링(4)에 의해 차단되어지게 된다.Accordingly, when the engine is driven and the engine negative pressure is applied, the engine oil sucked into the combustion chamber through the gap between the valve stem 1 and the valve guide 2 is blocked by the oil ring 4.
이상과 같은 본 고안은 밸브스템 외주면에 링 그루우브를 형성하고 그 링 그루우브에 밸브가이드 내벽면에 탄력적으로 밀착하는 오일링을 계합하는 것에 의해서 밸브스템과 밸브가이드의 틈새를 통한 엔진오일의 연소실 유입을 차단하게 되므로써 엔진오일의 과소모 및 배기가스 악화를 방지하며 밸브가이드 내벽면에 침착되는 카본이 오일링에 의해 긁혀 제거되는 효과가 있다.The present invention as described above forms a ring groove on the outer surface of the valve stem and engages the oil ring which elastically closely contacts the inner wall surface of the valve guide to the ring groove, so that the combustion chamber of the engine oil through the gap between the valve stem and the valve guide. By blocking the inflow, it prevents excessive consumption of engine oil and deterioration of exhaust gas, and the carbon deposited on the inner wall of the valve guide is scratched and removed by the oil ring.
