본 고안은 자동차의 실린더헤드에 설치된 흡·배기 밸브에 관한 것으로, 더욱 상세하게 설명하면 밸브장치의 구성을 간소화시킬 수 있도록 된 흡·배기 일체형 밸브에 관한 것이다.The present invention relates to an intake / exhaust valve installed in a cylinder head of an automobile, and more particularly, to an intake / exhaust integrated valve capable of simplifying the configuration of the valve device.
일반적으로, 자동차의 엔진에는 상부측의 덮개를 이루는 실린더헤드가 장착되는데, 이 실린더헤드에는 통상 한 개씩의 흡기밸브와 배기밸브가 장착되어 있다.In general, an engine of an automobile is equipped with a cylinder head that forms an upper lid, and the cylinder head is usually equipped with one intake valve and an exhaust valve.
그러나, 최근에는 엔진의 성능향상과 완전연소의 수단으로 흡기밸브와 배기밸브를 각각 두 개씩 구비한 밸브장치를 주로 사용하고 있다.Recently, however, a valve device including two intake valves and two exhaust valves is mainly used as a means of improving engine performance and completely burning the engine.
그 구성은 다음과 같다.The configuration is as follows.
제1도는 종래의 밸브가 장착된 상태를 도시한 저면도이며, 제2도는 종래의 밸브가 장착된 상태를 도시한 단면도로서,1 is a bottom view showing a state in which a conventional valve is mounted, and FIG. 2 is a cross-sectional view showing a state in which a conventional valve is mounted.
제1도에서와 같이, 두 개의 흡기밸브(21)와 두 개의 배기밸브(21)를 각각 구비한 종래의 밸브장치는 제2도에 도시된 바와 같이, 캠축(24)에 형성된 캠(25)에 의하여 회동하는 로커아암(23)을 각각 구비하고, 상단에 스프링(22)이 결합되어 캠(25)으로 회동하는 로커아암(23)에 의하여 개폐되는 흡기밸브(21a)와 배기밸브(21b)를 실린더 헤드에 결합한 것이다.As shown in FIG. 1, a conventional valve device having two intake valves 21 and two exhaust valves 21, respectively, has a cam 25 formed on the camshaft 24, as shown in FIG. Intake valves 21a and exhaust valves 21b each having a rocker arm 23 rotated by a spring and having a spring 22 coupled to an upper end thereof and opened and closed by a rocker arm 23 rotated by a cam 25. To the cylinder head.
따라서, 각각의 밸브(21a,21b)마다 로커아암(23)과 스프링(22)과 캠(25)이 형성된 종래의 밸브장치는 흡기행정일 때 두개의 흡기밸브(21a)를 모두 열어 흡기효율을 향상시켜 완전연소를 이루어 자동차 엔진성능을 향상시키게 된다. 물론, 배기밸브(21b)도 두 개가 구비되어 있으므로 배기효율을 높임과 동시에 공기의 흡입량을 늘려 엔진성능을 향상시킬 수 있게 되는 것이다.Therefore, the conventional valve device in which the rocker arms 23, the springs 22, and the cams 25 are formed for each of the valves 21a and 21b opens both intake valves 21a during the intake stroke, thereby improving intake efficiency. It will improve the engine performance of the car by perfect combustion. Of course, since the exhaust valve 21b is also provided with two, it is possible to improve the engine performance by increasing the exhaust efficiency and increasing the air intake.
그러나, 실린더헤드에 두 개의 흡기밸브(21a) 두 개의 배기밸브(21b) 즉, 총 네 개의 밸브(21a,21b)를 구비함으로, 예컨대 부가적으로 로커아암(23)과 캠(25)과 스프링(22)이 구비되므로, 그 구성이 무척 복잡하고 생산단가도 상승하며 엔진의 무게도 증가하는 문제점이 있었다.However, the cylinder head is provided with two intake valves 21a and two exhaust valves 21b, that is, four valves 21a and 21b in total, for example additionally the rocker arm 23, the cam 25 and the spring. Since the 22 is provided, the configuration is very complicated, the production cost is increased, and the weight of the engine is also increased.
이에, 본 고안은 상기와 같은 문제점을 해결하기 위하여 안출한 것으로, 더욱 상세하게 설명하면 밸브장치의 구성을 간소화할 수 있도록 한 구성을 제공하는 것을 본 고안의 목적으로 한다.Accordingly, the present invention has been made in order to solve the above problems, and in more detail, it is an object of the present invention to provide a configuration to simplify the configuration of the valve device.
상기 목적을 달성하기 위한 본 고안의 구성은, 밸브장치의 구성을 간소화할 수 있도록, 흡기 밸브헤드와 배기 밸브헤드를 일체로 형성하고 밸브 헤드의 배면에 밸브가 회동하지 않도록 가이드를 형성한 밸브 두 개를 구비하고, 흡입시는 부압에 의하여 배기쪽은 닫히고 흡기쪽은 부압에 의하여 열리며 배기시는 흡기쪽은 배기압에 의하여 닫히고 배기쪽은 배기압에 의하여 열릴 수 있도록 서로 역으로 개폐되는 원 웨이 밸브를 흡기구와 배기구에 각각 형성하며 캠축에는 흡기와 배기시 밸브를 개폐시키는 로커아암을 회동시킬 수 있도록 흡기와 배기행정을 일체로 형성한 캠을 형성함으로 상술한 소기의 목적을 달성할 수 있다.The configuration of the present invention for achieving the above object, the two valves in which the intake valve head and the exhaust valve head integrally formed so as to simplify the configuration of the valve device, and the guide is formed on the back of the valve head so that the valve does not rotate The inlet side is closed by the negative pressure during intake, the intake side is opened by the negative pressure, and the inlet side is opened and closed by the exhaust pressure so that the intake side is opened by the exhaust pressure. The above-described purpose can be achieved by forming a way valve at each of the intake and exhaust ports, and forming a cam at the camshaft so as to rotate the rocker arms that open and close the valves during intake and exhaust. .
이하, 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, described in detail with reference to the drawings.
제3도는 본 고안의 밸브 장착상태 저면도이고, 제4도는 본 고안의 밸브 장착상태 단면도로서,Figure 3 is a bottom view of the valve mounting state of the present invention, Figure 4 is a cross-sectional view of the valve mounting state of the present invention,
본 고안의 구성은, 흡기밸브와 배기밸브를 각각 두 개씩 구비한 자동차의 실린더헤드에 장착되는 밸브장치에 있어서, 실린더헤드에 흡기밸브와 배기밸브가 한 몸체를 이루도록 밸브헤드(1a)를 일체로 형성한 두 개의 밸브(1)가 장착되되, 밸브헤드(1a)의 배면에 밸브(1)가 왕복이동하는 과정에서 회동하는 것을 방지하기 위한 가이드(2)가 장착되며, 실린더헤드(A)의 흡기구(31)와 배기구(32)에 서로 역으로 개폐되는 원웨이밸브(6)가 장착되고, 캠축(5)에 흡기와 배기행정을 일체로 형성한 캠(4)이 장착된 구조로 되어 있다.The configuration of the present invention is a valve device mounted on a cylinder head of an automobile provided with two intake valves and two exhaust valves, wherein the valve head 1a is integrally formed so that the intake valve and exhaust valve form a body in the cylinder head. Two valves 1 formed are mounted, and a guide 2 is mounted on the rear surface of the valve head 1a to prevent the valve 1 from rotating during the reciprocating movement. The intake port 31 and the exhaust port 32 are equipped with a one-way valve 6 which is opened and closed in reverse with each other, and the cam shaft 5 is equipped with a cam 4 integrally formed with the intake and exhaust strokes. .
그리고, 제3도에 도시된 바와 같이, 밸브장치의 구성을 간소화할 수 있도록 연소실에 두 개를 구비한 밸브(1)는 흡기 밸브헤드와 배기 밸브헤드를 일체로 형성하고, 제4도에 도시된 바와 같이 밸브헤드(1a)의 배면에 밸브(1)가 회동하지 않도록 가이드(2)를 형성한다.And, as shown in FIG. 3, the valve 1 having two in the combustion chamber so as to simplify the configuration of the valve device, the intake valve head and the exhaust valve head are integrally formed, as shown in FIG. As described above, the guide 2 is formed on the rear surface of the valve head 1a so that the valve 1 does not rotate.
또한, 제4도에 도시된 바와 같이, 흡입시는 부압에 의하여 배기쪽은 닫히고 흡기쪽은 부압에 의하여 열리며, 배기시는 흡기쪽은 배기압에 의하여 닫히고 배기쪽은 배기압에 의하여 열릴 수 있도록 한 원 웨이 밸브(6)는 흡기구(31)와 배기구(31)에 서로 역으로 개폐되도록 각각 형성된다.In addition, as shown in FIG. 4, the intake side is closed by the negative pressure and the intake side is opened by the negative pressure during intake, and the intake side can be closed by the exhaust pressure and the exhaust side can be opened by the exhaust pressure. One-way valve 6 is formed so as to open and close inversely to each other in the inlet port 31 and the exhaust port 31.
그리고, 캠축(5)의 외면에 흡기와 배기시 밸브(1)를 개폐시키는 로커아암(3)을 회동시킬 수 있도록 한 캠(4)을 흡기행정과 배기행정을 일체로 하여 형성한다.On the outer surface of the camshaft 5, a cam 4, which allows the rocker arm 3 to rotate the intake and exhaust valves 1 to open and close, is formed integrally with the intake stroke and the exhaust stroke.
이하, 본 고안에 따른 작용과 효과에 대하여 상세하게 설명하면 다음과 같다.Hereinafter, the operation and effects according to the present invention will be described in detail.
먼저, 자동차의 엔진을 이루는 연소실로 혼합가스를 공급하는 흡기행정일 때는, 캠(4)에 의해 축회전하는 로커아암(3)이 스프링의 힘을 이기면서 밸브(1)를 개방시키게 된다.First, in the intake stroke for supplying the mixed gas to the combustion chamber constituting the engine of the automobile, the rocker arm 3 axially rotated by the cam 4 opens the valve 1 while beating the spring force.
이때, 캠축(5)을 이루는 캠(4)은 흡/배기행정이 일체로 형성된 상태이므로 예컨대, 흡기쪽의 원웨이밸브(6)가 열리게 되면 배기쪽의 원웨이밸브(6)는 닫히게 된다.At this time, since the cam 4 constituting the camshaft 5 has an intake / exhaust stroke formed integrally, for example, when the one-way valve 6 on the intake side is opened, the one-way valve 6 on the exhaust side is closed.
물론, 엔진의 연소실은 피스톤이 하향된 상태에서 부압상태를 유지하므로, 혼합가스가 연소실내로 원활하게 유입된다.Of course, since the combustion chamber of the engine maintains a negative pressure in a downward state of the piston, the mixed gas flows smoothly into the combustion chamber.
이때, 밸브(1)는 로커아암(3)의 축회동에 의해 개방되는 과정에서 예컨대, 가이드(2)에 의해 이동이 안내되므로, 밸브(1)의 유동이나 회동이 방지된 상태이다.At this time, the valve 1 is guided by, for example, the guide 2 in the process of opening by the axial rotation of the rocker arm 3, so that the flow or rotation of the valve 1 is prevented.
한편, 자동차의 엔진 연소실의 압축과 폭발행정이 완료되고 배기행정일 때는, 캠축(5)의 캠(4)에 의해 축회동하는 로커아암(3)이 회동하면서 밸브(1)를 개방시키게 된다.On the other hand, when the compression and explosion stroke of the engine combustion chamber of the automobile are completed and the exhaust stroke is performed, the rocker arm 3 pivoting by the cam 4 of the cam shaft 5 rotates to open the valve 1.
이때, 엔진 연소실의 배기압에 의해 흡입구(31)쪽의 원웨이밸브(6)는 닫히게 되고 동시에, 배기구(32)쪽의 원웨이밸브(6)는 개방되므로, 배기구(32)를 통해 배기가스가 외부로 배출되는 것이다.At this time, the one-way valve 6 on the inlet 31 is closed by the exhaust pressure of the engine combustion chamber, and at the same time, the one-way valve 6 on the exhaust port 32 is opened, so that the exhaust gas is exhausted through the exhaust port 32. Is discharged to the outside.
이상에서 설명한 바와 같이 본 고안에 따른 흡·배기 일체형 밸브에 의하면, 흡/배기밸브가 한 몸체를 이루도록 밸브헤드를 일체로 형성한 두개의 밸브를 장착하므로, 밸브장치의 구성을 간소화하여 엔진을 경량화하며 생산단가를 낮추고 생산공정을 간소화하여 생산성을 높인 매우 유용한 것이다.As described above, according to the intake / exhaust integrated valve according to the present invention, since two valves are integrally formed so that the intake / exhaust valves form one body, the engine is lightened by simplifying the configuration of the valve device. It is very useful to increase the productivity by lowering the production cost and simplifying the production process.
