본 고안은 내연기관에서 실린더헤드 상부와 실린더헤드커버의 접합면사이에 장착되는 개스킷의 구조에 관한 것을, 특히 개스킷장착시 실린더헤드와 실린더헤드커버사이의 내측틈새에 괴여 있는 윤활오일이 개스킷과 실린더헤드커버의 접촉면을 타고 외부로 누유되는 것이 방지되도록 개선된 실린더헤드커버 부착용 개스킷의 구조에 관한 것이다.The present invention relates to a structure of a gasket mounted between an upper surface of a cylinder head and a joining surface of a cylinder head cover in an internal combustion engine. In particular, when the gasket is mounted, the lubricating oil stuck to the inner gap between the cylinder head and the cylinder head cover, It relates to a structure of a cylinder head cover attachment gasket improved to prevent leakage to the outside on the contact surface of the head cover.
통상 실린더헤드 상부와 실린더헤드커버 사이의 내부공간상에는 크랭크저널등의 회전운동으로 비산되거나 로커아암등에서 낙하된 윤활오일과 피스톤폭발행정시 실린더와 틈새로 누출된 블로우바이가스등이 함께 뒤섞여 있다.In general, the inner space between the cylinder head upper portion and the cylinder head cover is mixed with lubricating oil scattered by the rotational movement of the crank journal or the like, and the blow-by gas leaked into the cylinder and the gap during the piston explosion stroke.
따라서 실린더헤드 상부에 설치된 로커아암등을 보호하기 위해 설치된 실린더헤드커버에는 실린더헤드와의 접촉면상에 보통 개스킷이 부착되어 있어, 실린더헤드커버 내부공간상에 함유된 블로우가스나 윤활오일이 외부로 누유나 누출되는 것을 방지하도록 되어진다.Therefore, the cylinder head cover installed to protect the rocker arm installed on the cylinder head is usually attached to the contact surface with the cylinder head, so that blow gas or lubricating oil contained in the inner space of the cylinder head cover is leaked to the outside. It is to prevent leakage.
그러나 종래의 실린더헤드커버에 부착되는 개스킷의 구조는 제2도에 도시된 바와같이 개스킷(11)을 중심으로 개스킷(11)이 설치된 실린더헤드(12) 상부와 실린더헤드커버(13)의 접합면상 내·외측에 틈새가 형성되어지게 되어 있어서, 이 틈새중 내측틈새(14)상에 괴여있던 윤활오일(16)이 엔진의 진동 및 실린더헤드커버(13)내 공간(15)과 외부의 압력차이로 인하여 개스킷(11)과 상기 실린더헤드커버(13)의 접합부위를 타고 외부(화살표 방향)로 누유되어 오일소모량을 증대시키고 엔진외부의 관련부품을 오염시키게 되는 원인이 되어 왔다.However, the structure of the gasket attached to the conventional cylinder head cover is as shown in FIG. 2 on the joining surface of the cylinder head 12 and the cylinder head cover 13 in which the gasket 11 is installed around the gasket 11. Since a gap is formed inside and outside, the lubricating oil 16 stuck on the inside gap 14 is caused by vibration of the engine and pressure difference between the space 15 in the cylinder head cover 13 and the outside. Due to this, the gasket 11 and the cylinder head cover 13 are leaked to the outside (in the direction of the arrow), which causes oil leakage to increase and contaminate related parts outside the engine.
이에 본 고안은 상기와 같은 제반문제점을 해결하기 위해 안출된 것으로서, 실린더헤드커버 내측상부벽에 접착된 윤활오일이 내측틈새상에 고이지 않고 그대로 실린더헤드 상부로 흘러내리도록 그 형상구조가 개선된 실린더헤드커버 부착용 개스킷의 구조를 제공하는데 그 목적이 있다.Therefore, the present invention was devised to solve the above problems, and the lubricating oil adhered to the inner upper wall of the cylinder head cover does not accumulate on the inner gap and flows to the upper portion of the cylinder head as it is. It is an object of the present invention to provide a structure of a gasket for attaching a head cover.
상기와 같은 목적을 달성하기 위해 본 고안은 실린더헤드와 개스킷이 부착된 실린더헤드커버 조립시 형성되는 내측틈새를 메울 수 있도록 개스킷의 측단에 메움부가 신설되어진다.In order to achieve the above object, the present invention has a new filling part at the side end of the gasket so as to fill the inner gap formed when the cylinder head cover is assembled with the cylinder head and the gasket.
이하 본 고안을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제1도는 실린더헤드와 실린더헤드커버 사이의 본 고안에 따른 개스킷이 장착된 상태를 나타낸 단면도로서, 본 고안 개스킷(1)은 실린더헤드(2)상부에 실린더헤드커버(3)를 조립할 때 접합부위에 형성되는 내측틈새(4)를 메울수 있도록 측단에 ㄱ자형상의 메움부(1a)가 형성되어지되, 이 메움부(1a)의 내측 끝단이 공간(5)상에 돌출되어, 실린더헤드(2) 내측벽에 밀착되게 부착되어 진다.1 is a cross-sectional view showing a state in which a gasket according to the present invention is mounted between a cylinder head and a cylinder head cover, and the gasket 1 of the present invention is attached to a joint when the cylinder head cover 3 is assembled on the cylinder head 2. A-shaped filling portion 1a is formed at the side end so as to fill the inner gap 4 formed, and the inner end of the filling portion 1a protrudes on the space 5, thereby providing a cylinder head 2 It is attached closely to the inner wall.
따라서 상기와 같은 구조로 된 본 고안은, 공간(5)내에서 비산하거나 실린더헤드커버(3) 측벽상에 접착되어 흘러내리는 윤활오일(6)이 상기 개스킷(1)의 메움부(1a)에 의해 내측틈새(4)상에 고이지 못하고 실린더헤드(2)상부로 낙하되어진다.Therefore, the present invention having the structure as described above, the lubricating oil (6) scattered in the space (5) or adhered to the cylinder head cover (3) side wall flows to the filling portion (1a) of the gasket (1) As a result, they do not accumulate on the inner gap 4 and fall on the cylinder head 2.
그러므로 상기와 같은 본 고안은, 종래 개스킷부착시 형성되던 내측틈새 공간상에 윤활오일의 굄이 원칙적으로 방지되어 개스킷의 오일누유방지효과가 향상되어지고 불필요한 윤활오일의 소모가 예방되어지는 잇점이 있게 된다.Therefore, the present invention as described above has the advantage that the lubrication oil is prevented from leaking on the inner gap space formed when the gasket is conventionally attached, thereby improving the oil leakage prevention effect of the gasket and preventing the consumption of unnecessary lubrication oil. do.
