Description
본 고안은 자동차 엔진의 실린더헤드에 실린더헤드덮개를 고정할시 밀폐성향상을 위해서 설치되는 개스킷에 관한 것으로, 특히 밀폐성이 향상되어 블로우바이가스와 엔진오일의 누출이 방지되도록 된 자동차 엔진의 실린더헤드덮개용 개스킷에 관한 것이다.The present invention relates to a gasket which is installed to improve the sealing property when fixing the cylinder head cover to the cylinder head of the automobile engine, in particular, the cylinder head cover of the automobile engine to improve the sealing property to prevent the leakage of blow-by gas and engine oil Relates to a gasket.
주지된 바와 같이, 실린더헤드는 엔진의 머리부분으로 실린더 상측에 설치되어 실린더 및 피스톤과 함께 연소실을 형성하며, 내측의 연소실에는 스파크플러그, 흡입밸브, 배기밸브 등이 구비되고, 상부에는 흡입밸브와 배기밸브를 개폐하는 캠과 캠축이 설치되는 바, 이러한 실린더헤드의 상측에는 실린더헤드덮개가 설치된다.As is well known, the cylinder head is a head of the engine and is installed on the upper side of the cylinder to form a combustion chamber together with the cylinder and the piston, and the inner combustion chamber is provided with a spark plug, an intake valve, an exhaust valve, and the intake valve and an upper portion thereof. A cam and a camshaft for opening and closing the exhaust valve are installed, and a cylinder head cover is provided above the cylinder head.
상기 실린더헤드덮개는 실린더헤드에 먼지 등의 이물질이 쌓여 캠과 캠축의 구동 및, 흡입밸브와 배기밸브의 구동이 원활하게 이루어지지 못하는 것을 방지하고, 이를 보호하며 압축행정과 팽창행정시 발생되는 블로바이가스를 흡기계통으로 환원하는 등의 여러 가지 역할을 한다.The cylinder head cover prevents the driving of the cam and the cam shaft and the driving of the intake valve and the exhaust valve smoothly due to the accumulation of foreign matter such as dust on the cylinder head. It serves a variety of roles, such as reducing the gas to the intake cylinder.
한편, 실린더헤드에 실린더헤드덮개를 고정할시 실린더헤드와 실린더헤드덮개 사이에 개스킷을 삽입하여 엔진오일 및 블로바이가스의 누출을 방지하는데, 종래 실린더헤드덮개용 개스킷은 도 3에 도시되어 있는 바, 실린더헤드(2)의 상측 체결부에 다수의 체결홈이 형성된 -형태의 개스킷(13)이 얹혀지고, 이 개스킷(13)의 상면에 실린더헤드덮개(1)의 체결부가 얹혀져 보울트(4)를 매개로 상기 실린더헤드(2)와 개스킷(13) 및 실린더헤드덮개(1)가 일체화 되어 있다.Meanwhile, when the cylinder head cover is fixed to the cylinder head, a gasket is inserted between the cylinder head and the cylinder head cover to prevent leakage of engine oil and blow-by gas. The conventional cylinder head cover gasket is shown in FIG. 3. A gasket 13 having a plurality of fastening grooves is mounted on the upper fastening portion of the cylinder head 2, and the fastening portion of the cylinder head cover 1 is placed on the upper surface of the gasket 13 so that the bolt 4 can be mounted. The cylinder head 2, the gasket 13, and the cylinder head cover 1 are integrated with each other.
따라서, 실린더헤드(2)와 실린더헤드덮개(1)의 접합면에 약간의 凹凸이나 접촉면의 오차가 발생되더라도 상기 개스킷(13)이 이를 흡수하여 기밀이 보전됨으로써 엔진오일이나 블로바이가스의 누출이 방지된다.Therefore, even if a slight gap or contact surface error occurs at the joint surface of the cylinder head 2 and the cylinder head cover 1, the gasket 13 absorbs it and preserves airtightness, thereby preventing leakage of engine oil or blow-by gas. Is prevented.
그러나, 상기 종래 개스킷(13)은 단면이 -형태로 되어 실린더헤드덮개(1) 내측의 블로바이가스 압력이 증가되면 이러한 압력에 의해 고무재질의 상기 개스킷(13)이 외측으로 밀리게 되는데, 이로 인하여 엔진오일과 블로바이가스가 외부로 누출되어 엔진수명이 단축되고 대기오염이 증가되는 문제가 발생되었다.However, the conventional gasket 13 has a cross-section, so that when the blow-by gas pressure inside the cylinder head cover 1 is increased, the pressure of the gasket 13 is pushed outward by the pressure. As a result, engine oil and blow-by gas leaked to the outside, resulting in a problem of shortening the engine life and increasing air pollution.
이에 본 고안은 상기와 같은 문제를 해소하기 위하여 안출된 것으로, 밀폐성이 향상되어 블로바이가스와 엔진오일의 누출이 방지되동록 하는 자동차 엔진의 실린더헤드덮개용 개스킷을 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, the object of the present invention is to provide a gasket for a cylinder head cover of an automobile engine to improve the sealing property to prevent the leakage of blow-by gas and engine oil.

상기와 같은 목적을 달성하기 위한 본 고안은, 다수의 체결홈이 형성되어 실린더헤드와 실린더헤드덮개 사이에 보울트를 매개로 체결되는 단념이 -형태의 자동차 엔진의 실린더헤드덮개용 개스킷에 있어서, 상기 개스킷의 단면이 ㄷ자 형태로 이루어진 구조로 되어 있다.The present invention for achieving the above object, in the gasket for the cylinder head cover gasket of the motor vehicle engine of the -type that is formed through a bolt between the cylinder head and the cylinder head cover is formed a plurality of fastening grooves, The cross section of the gasket has a U-shaped structure.
이하 본 고안을 첨부된 예시도면에 의거하여 실시예를 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 고안에 따른 실린더헤드덮개용 개스킷이 설치되어진 엔진의 사시도이고, 도 2는 도 1의 Ⅰ-Ⅰ선 단면도인 바, 종래 기술을 도시한 도 3과 동일한 부위에는 동일한 참조부호를 붙이면서 그 설명을 생략한다.1 is a perspective view of an engine in which a gasket for a cylinder head cover according to the present invention is installed, and FIG. 2 is a cross-sectional view taken along the line I-I of FIG. 1, with the same reference numerals as in FIG. The description is omitted.
이에 따르면, 실린더헤드(2)의 상측 체결부에 다수의 체결홈이 형성된 ㄷ자 형태의 개스킷(3)이 얹혀지고, 이 개스킷(13)의 상면에 실린더헤드덮개(1)의 체결부가 얹혀져 보울트(4)를 매개로 상기 실린더헤드(2)와 개스킷(3) 및 실린더헤드덮개(1)가 일체화 되어 있다.According to this, a g-shaped gasket 3 having a plurality of fastening grooves is placed on the upper fastening portion of the cylinder head 2, and the fastening portion of the cylinder head cover 1 is placed on the upper surface of the gasket 13 so that the bolt ( The cylinder head 2, the gasket 3 and the cylinder head cover 1 are integrated with each other via 4).
따라서, 실린더헤드덮개(1) 내측의 블로바이가스 압력이 증가되더라도 상기 개스킷(3)의 선단이 실린더헤드덮개(1)의 내측에 걸리게 됨으로써 상기 종래 기술에서 언급한 바와 같은 개스킷(13)이 외측으로 밀리는 것이 방지되어 밀폐성이 향상된다.Therefore, even when the blow-by gas pressure inside the cylinder head cover 1 is increased, the front end of the gasket 3 is caught by the inside of the cylinder head cover 1, so that the gasket 13 as mentioned in the prior art is outward. Is prevented from being pushed to improve the sealing property.
이상 상기한 바와 같은 본 고안에 따르면, 개스킷의 단면이 ㄷ형태로 됨으로써 밀폐성이 향상되어 엔진오일과 블로바이가스가 외부로 누출되는 것이 방지됨에 따라 엔진의 수명이 연장되고 대기오염이 저하되는 효과가 있다.According to the present invention as described above, as the cross section of the gasket is in the form of c, the sealing property is improved, so that the engine oil and blow-by gas are prevented from leaking to the outside, thereby extending the life of the engine and reducing the air pollution. have.
