먼저, 본 고안의 실험용 단기통기관도 도 2에 도시되는 바와 같이, 동력발생부인 실린더가 하나로 형성되는 실린더블록(10)의 상부에 연소실 상부를 형성하는 실린더헤드(20)가 기밀하게 결합되고, 실린더블록(10)의 하부에 엔진오일이 저장되는 오일팬이 취부되며, 실린더헤드(20)의 양측 상부에 밸브와 캠(40) 및 캠축을 덮는 커버(30)가 결합된다.First, as shown in FIG. 2, the experimental short-duration pipe of the present invention also has a cylinder head 20 that forms an upper combustion chamber on an upper portion of a cylinder block 10 in which a cylinder, which is a power generating unit, is formed in an airtight manner. An oil pan in which engine oil is stored is mounted at a lower part of the block 10, and a valve, a cam 40, and a cover 30 covering the cam shaft are coupled to both upper portions of the cylinder head 20.
단, 본 고안은 도 2와 도 3에 도시되는 바와 같이, 커버(30)의 저면에 외곽부를 따라 요홈부가 형성되어 상기 요홈부에 소정 탄성을 가지는 고무링(31)이 삽입됨을 그 기술적 구성상의 기본 특징으로 한다.However, the present invention, as shown in Figure 2 and 3, the groove portion is formed along the outer portion on the bottom surface of the cover 30, the rubber ring 31 having a predetermined elasticity is inserted into the groove portion It is a basic feature.
이와같이 구성되는 본 고안은, 고무링(31)을 커버(30)의 요홈부에 삽입시킨 후 커버(30)를 실린더헤드(20)의 상부에 결합하며 이렇게 결합된 고무링(31)이 실린더헤드(20) 상면에 탄력적으로 밀착되어 기밀을 유지하게 된다. 또한, 기관의 작동중 엔진오일이 실린더헤드(20) 상부의 작동부인 밸브와 캠(40) 및 캠축에 공급되어 윤활작용을 하고, 이송중인 일부 오일이 실린더헤드(20) 상면에 떨어지면 고무링(31)에 의해 이동이 제한되어 다시 오일팬을 회수되도록 한다.According to the present invention configured as described above, the rubber ring 31 is inserted into the recess of the cover 30, and then the cover 30 is coupled to the upper portion of the cylinder head 20, and the rubber ring 31 thus coupled is the cylinder head. (20) It is elastically in close contact with the upper surface to maintain airtightness. In addition, during operation of the engine, the engine oil is supplied to the valve, the cam 40 and the camshaft, which are operating parts of the cylinder head 20, and lubricated, and when some oil being transferred falls on the upper surface of the cylinder head 20, the rubber ring ( 31) the movement is limited so that the oil pan can be recovered again.
상기와 같이 구성되고 작동되는 본 고안은, 고무링이 커버와 실린더헤드사이에 온전한 기밀작용을 하여 캠 및 밸브 작동부에서 떨어진 오일이 외부로 누출되는 것을 방지하고, 고무링이 커버의 홈에 끼워진 상태에서 그대로 조립하므로 조립이 정확하고 편리하게 되는 효과를 갖는다.The present invention is constructed and operated as described above, the rubber ring has an intact airtight action between the cover and the cylinder head to prevent leakage of oil dropped from the cam and the valve operating portion to the outside, the rubber ring is fitted into the groove of the cover Since the assembly as it is in the state has the effect that the assembly is accurate and convenient.
본 고안은 실험용 단기통기관의 밸브커버 결합구조에 관한 것으로, 실린더헤드 상부와 커버 저면의 결합구조를 개선하여 엔진오일의 누유를 방지하고 분해조립이 정확하고 편리하도록 하는 데 그 목적이 있다.The present invention relates to the valve cover coupling structure of the experimental short-term pipe, the purpose is to improve the coupling structure of the upper cylinder head and the bottom cover to prevent leakage of the engine oil and to accurately and convenient disassembly and assembly.
