Description
본 고안은 밸브가이드의 오일침입 차단구조에 관한 것이다.The present invention relates to an oil intrusion blocking structure of the valve guide.
밸브(2)는 제3도에 도시하는 것과 같이 흡기(배기)포트(10)를 개폐하기 위하여 고속으로 직선 왕복운동을 하며 실린더헤드(3)에는 밸브(2)의 운동을 안내하는 밸브가이드(1)가 매입되어 있다.The valve 2 is linearly reciprocated at high speed to open and close the intake (exhaust) port 10 as shown in FIG. 3, and the cylinder head 3 has a valve guide for guiding the movement of the valve 2. 1) is purchased.
그러나 밸브(2)의 고속운동을 안내하여야 하기 때문에 밸브가이드(1)와 밸브스템(2a) 사이에는 어느정도 틈새가 형성되기 때문에 엔진의 흡기부압이 작용시 이 틈새를 통하여 캠축과 밸브트레인의 윤활 및 냉각을 위해 로커카바내에 공급된 엔진오일이 연소실로 침투하여 오일소모를 증대시키고 대기오염을 유발하게 된다.However, because the high speed movement of the valve 2 must be guided, a gap is formed between the valve guide 1 and the valve stem 2a. Therefore, when the intake underpressure of the engine is applied, the cam shaft and the valve train are lubricated and Engine oil supplied in the rocker cover for cooling penetrates into the combustion chamber, increasing oil consumption and causing air pollution.
이 때문에 밸브가이드(1)의 상단에는 시일부재(4)를 장착하고 있으나 시일부재에 의해서도 어느정도의 오일 침투를 피할 수는 없다.For this reason, although the sealing member 4 is attached to the upper end of the valve guide 1, some oil penetration cannot be avoided even by the sealing member.
그러나 시일부재(4)를 통과한 엔진오일은 밸브스템(2a) 표면을 타고 흘러내려 밸브스템(2a)에 오일슬러지(11)를 침적시키게 되므로써 불필요한 오일소모와 더불어 인젝터(12)로부터 분사되는 연료의 무화를 방해하고 밸브스템(2a) 표면에 부딪히는 연료의 이슬맺힘으로 인하여 연소성능이 저하되는 문제점이 있게 된다.However, the engine oil passing through the seal member 4 flows down the surface of the valve stem 2a to deposit the oil sludge 11 on the valve stem 2a, so that the fuel injected from the injector 12 together with unnecessary oil consumption. There is a problem that the combustion performance is deteriorated due to the dew condensation of the fuel impinging on the surface of the valve stem (2a).
이에 본 고안은 상기한 문제점을 감안하여 제안된 것으로서 그의 목적으로 하는 것은 엔진오일의 연소실로의 침입을 차단하여 오일소모를 저감하고 밸브스템 표면에의 분사연료의 이슬맺힘을 방지하게 되는 밸브가이드의 오일침입 차단구조를 제공하는 데 있다.The present invention has been proposed in view of the above problems, and its purpose is to block the intrusion of engine oil into the combustion chamber to reduce oil consumption and prevent dew condensation of the injection fuel on the surface of the valve stem. An oil penetration blocking structure is provided.
상기한 목적을 달성하기 위하여 본 고안은 밸브의 왕복작동을 안내하는 밸브가이드에 있어서, 상기 밸브가이드 하단 내측에 형성되는 요홈에 끼워져 밸브스템을 타고 흘러내리는 엔진오일을 흡수하여 차단하는 오일흡수필터와; 나트륨액이 봉입되어 있으며 상기 오일흡수필터내에 내장되는 알루미늄 케이스와; 엔진열에 의해 열팽창하므로써 상기 오일흡수용 필터가 밸브스템 표면에 밀착하도록 가압하는 왁스체와; 를 포함하여 구성되는 것을 특징으로 한다.In order to achieve the above object, the present invention provides a valve guide for reciprocating a valve, comprising: an oil absorption filter for absorbing and blocking engine oil flowing through a valve stem inserted into a recess formed in the lower side of the valve guide; ; An aluminum case encapsulated with sodium liquid and embedded in the oil absorption filter; A wax body for pressurizing the oil absorption filter to be in close contact with the valve stem surface by thermal expansion by engine heat; Characterized in that comprises a.

이하 본 고안의 구성과 작용을 첨부한 도면을 참조하여 설명한다.Hereinafter, with reference to the accompanying drawings the configuration and operation of the present invention.
제1도는 본 고안에 의한 밸브가이드의 오일침입 차단구조를 나타내는 도면이며 제2도는 본 고안의 요부 상세도로서 도면중 부호 1은 밸브(2)의 왕복운동을 안내하도록 실린더헤드(3)에 매입되는 밸브가이드이다.1 is a view showing the oil intrusion blocking structure of the valve guide according to the present invention, and FIG. 2 is a detailed view of the main part of the present invention, in which 1 is embedded in the cylinder head 3 to guide the reciprocating motion of the valve 2. Valve guide.
상기 밸브가이드(1)의 상부에는 오일시일부재(4)가 마련되고 그의 하부에는 요홈(5)이 형성된다.An oil seal member 4 is provided at an upper portion of the valve guide 1, and a recess 5 is formed at a lower portion thereof.
그 요홈(5)내에는 오일흡수용 필터(6)가 수용되며 오일흡수용 필터(6) 내부에는 알루미늄 케이스(7)가 내장되고 그 알루미늄 케이스(7) 내부에는 열전달 효율이 좋아 냉각 특성을 좋게하는 물질로서 잘 알려져 있는 나트륨액(8)이 봉입되어져 있다.An oil absorption filter 6 is accommodated in the recess 5, and an aluminum case 7 is built in the oil absorption filter 6, and the heat transfer efficiency is good in the aluminum case 7 to improve cooling characteristics. Sodium liquid 8, which is well known as a substance, is encapsulated.
그리고 요홈(5)의 외곽쪽으로는 왁스체(9)가 충진되어 있다.The wax body 9 is filled in the outer side of the groove 5.
이와같은 본 고안은 연소실의 온도에 의해서 왁스체(9)가 열팽창을 일으켜서 오일흡수용 필터(6)에 가압력을 가하여 밸브스템(2a) 표면에 밀착되도록 하여 엔진오일이 밸브스템(2a) 표면을 통하여 흘러내리는 것을 차단하고 흡수하여 간직하게 된다.In the present invention, the wax body 9 thermally expands due to the temperature of the combustion chamber so that the oil absorbing filter 6 is pressed against the surface of the valve stem 2a so that the engine oil adheres to the surface of the valve stem 2a. It blocks and drips through and absorbs.
그리고 나트륨액(8)이 봉입된 알루미늄 케이스(7)는 밸브스템(2a)이 받는열을 방열 냉각시켜 오일흡수용 필터(6)가 열화되는 것을 방지하게 된다.The aluminum case 7 in which the sodium liquid 8 is encapsulated prevents the oil absorption filter 6 from deteriorating by dissipating and cooling the heat received by the valve stem 2a.
이상과 같은 본 고안에 의하면 엔진오일이 밸브스템을 타고 연소실로 침입하는 것 및 밸브스템 표면에 형성되는 오일슬러지의 침착을 방지하게 되므로써 오일 소모를 저감하고 배기가스 악화를 방지할 뿐 아니라 분사되는 연료가 밸브스템 표면에 물방울(Wettint) 형태로 맺혀 기화를 방해하는 일이 없게된다.According to the present invention as described above, the engine oil enters the combustion chamber through the valve stem and prevents the deposition of oil sludge formed on the surface of the valve stem, thereby reducing oil consumption and preventing exhaust gas deterioration, and also fuel injected. Is formed in the form of droplets (Wettint) on the surface of the valve stem does not interfere with vaporization.
