본 고안은 자동차 배기가스 정화용 배기가스 재순환 밸브에 관한 것으로, 특히 배기가스 재순환 밸브의 하우징에 물통로를 설치하여 배기가스를 냉각시킴으로써 배기가스 재순환 밸브의 내구성을 향상시키기 위한 것이다. 일반적으로 자동차의 배기가스를 정화하기 위한 배기가스 재순환 장치는 실린더헤드의 배기포트에서 흡기 매니홀드에 있는 포트로 배기가스의 일부분을 재순환 시킴으로써 배기가스 중의 질소화합물을 감소시키는 장치이다.The present invention relates to an exhaust gas recirculation valve for automobile exhaust gas purification, in particular to improve the durability of the exhaust gas recirculation valve by cooling the exhaust gas by installing a water passage in the housing of the exhaust gas recirculation valve. In general, an exhaust gas recirculation apparatus for purifying exhaust gas of a vehicle is a device for reducing nitrogen compounds in exhaust gas by recirculating a portion of the exhaust gas from an exhaust port of a cylinder head to a port in an intake manifold.
이와 같은 배기가스 재순환장치는 배기가스 재순환 밸브와 서머밸브와 상기 밸브들을 상호 연결시켜 주는 파이프로 구성되는 있는바, 기존의 배기가스 재순환 밸브의 구성을 첨부도면에 의거 설명하면 다음과 같다.Such an exhaust gas recirculation apparatus is composed of an exhaust gas recirculation valve, a summer valve, and a pipe connecting the valves to each other. A configuration of an existing exhaust gas recirculation valve will be described with reference to the accompanying drawings.
즉, 종래의 배기가스 재순환 밸브는 제1도에 도시된 바와 같이 배기가스의 유입구(10)와 배출구(11)가 형성되어 있는 하우징(12)과, 배기가스의 통로를 개폐할 수 있도록 상기 하우징(12)의 내부에 설치되어 있는 니들밸브(13)와 밸브시트(14)와, 상기 니들밸브(13)의 작동을 안내할 수 있도록 상기 니들밸브(13)의 외주에 설치되어 있는 부시(15)와 홀더(16)와, 상기 니들밸브(13)의 작동을 조정할 수 있도록 상기 하우징(12)의 상부에 설치되어 있는 다이어프램(17)과 스프링(18)과 케이스(19)로 구성되어 있다.That is, the conventional exhaust gas recirculation valve has a housing 12 in which the inlet 10 and the outlet 11 of the exhaust gas are formed as shown in FIG. 1, and the housing so as to open and close the passage of the exhaust gas. Needle valve 13 and valve seat 14 provided in the interior of 12, and a bush 15 provided on the outer circumference of the needle valve 13 to guide the operation of the needle valve 13; ), A holder (16), and a diaphragm (17), a spring (18), and a case (19), which are installed on an upper portion of the housing (12) to adjust the operation of the needle valve (13).
이와 같이 구성된 종래의 배기가스 재순환 밸브에는 흡기 매니홀드에서 나온 배기가스가 파이프로 통하여 직접 유입된다. 따라서 배기가스가 냉각되지 않고 고온인 상태로 직접 배기가스 재순환 밸브로 유입되는 관계로 배기가스 재순환 밸브의 각 구성부품들이 열해를 받아 내구성이 지하되는 문제점이 있었다.In the conventional exhaust gas recirculation valve configured as described above, the exhaust gas from the intake manifold is directly introduced through the pipe. Therefore, since the exhaust gas is not cooled and flows directly into the exhaust gas recirculation valve at a high temperature, each component of the exhaust gas recirculation valve is thermally damaged, and thus durability is underground.
본 고안은 이와 같은 문제점을 해결하기 위한 것으로, 배기가스 재순환 밸브의 하우징에 물통로를 설치하여 배기가스를 냉각시킴으로써 내구성을 향상시킨 자동차용 배기가스 재순환 밸브의 제공을 목적으로 한다.The present invention has been made to solve the above problems, and an object of the present invention is to provide a vehicle exhaust gas recirculation valve for improving durability by installing a water passage in the housing of the exhaust gas recirculation valve to cool the exhaust gas.
이와 같은 본 고안의 목적은 기존의 배기가스 재순환 밸브의 하우징의 내벽에 물통로를 설치하고, 상기 물통로에 엔진냉각수와 순환될수 있도록 엔진냉각수의 유입구와 배출구를 형성하며 상기 배기가스 재순환 밸브의 냉각을 시킴으로써 달성된다.The purpose of the present invention is to install a water passage on the inner wall of the housing of the existing exhaust gas recirculation valve, to form the inlet and outlet of the engine coolant to be circulated with the engine coolant in the water passage and to cool the exhaust gas recirculation valve Is achieved by
이하, 본 고안의 구성을 첨부도면에 의거 상세히 설명하면 다음과 같다.Hereinafter, the configuration of the present invention in detail based on the accompanying drawings.
즉, 제2도에 도시된 바와 같이, 본 고안은 배기가스의 유입구(10)와 배출구(11)가 형성되어 있는 하우징(12)과 배기가스의 통로를 개폐할 수 있도록 상기 하우징(12)의 내부에 설치되어 있는 니들밸브(13)와 밸브시트(14)와 상기 니들밸브(13)의 작동을 안내할 수 있도록 니들밸브(13)의 외주에 설치되어 있는 부시(15)와 홀더(16)와, 상기 니들밸브(13)의 작동을 조정할 수 있도록 상기 하우징(12)의 상부에 설치되어 있는 다이어프램(17)과 스프링(18)과 케이스(19)로 구성된 배기가스 순환밸브에 있어서 배기가스의 냉각을 위하여 상기하우징(12)의 내벽에 내장된 물통로(20)와, 상기 물통로(20)에 연결되도록 설치된 엔진냉각수의 유입구(21)와 배출구(22)로 구성되어 있다.That is, as shown in FIG. 2, the present invention provides a housing 12 in which the inlet 10 and the outlet 11 of the exhaust gas are formed and the passage of the exhaust gas so as to open and close a passage of the exhaust gas. The bush 15 and the holder 16 installed on the outer circumference of the needle valve 13 to guide the operation of the needle valve 13, the valve seat 14, and the needle valve 13 installed therein. And an exhaust gas circulation valve composed of a diaphragm 17, a spring 18, and a case 19 provided on the upper portion of the housing 12 so that the operation of the needle valve 13 can be controlled. It consists of a water passage (20) built into the inner wall of the housing 12 for cooling, and an inlet (21) and outlet 22 of the engine coolant installed to be connected to the water passage (20).
이와 같이 구성된 본 고안에 의하면, 고온인 상태로 배기가스 재순환 밸브에 직접 유입된 배기가스가 상기배기가스 재순환 밸브의 하우징에 형성된 물통로를 순환하는 엔진냉각수에 의하여 냉각됨으로써 상기 배기가스 재순환 밸브의 각 구성부품들이 열해를 받지않고 내구성이 향상되는 효과가 있다.According to the present invention configured as described above, each of the exhaust gas recirculation valve is cooled by engine coolant circulating through the water passage formed in the housing of the exhaust gas recirculation valve while the exhaust gas directly introduced to the exhaust gas recirculation valve is heated. The components are not thermally damaged and durability is improved.
