Description

오일제트의 체크밸브 { An check valve for a Oil jet }[0001] The present invention relates to a check valve for an oil jet,

본 고안은 오일제트의 체크밸브에 관한것으로서, 더욱 상세하게는 엔진의 실The present invention relates to an oil jet check valve, and more particularly,

린더에서 왕복운동하며 연소실의 폭발력을 커넥팅로드를 통해 크랭크샤프트And the explosive force of the combustion chamber is transmitted through the connecting rod to the crankshaft

로 전달하는 피스톤을 냉각시키는 장치인 오일제트의 체크밸브 구조를 개선To improve the check valve structure of the oil jet,

한 것이다.It is.

종래의 체크밸브 구조는 도3에 도시한 바와 같이 밸브 하우징(2)의 내부 실As shown in Fig. 3, the conventional check valve structure has a structure in which the inner chamber of the valve housing 2

린더실(9)에서 스프링(10)으로 탄력지지되면서 실린더벽(9')을 타고 습동되Is supported by the spring (10) in the liner chamber (9) while being swept by the cylinder wall (9 '),

는 밸브(11')가 플런저 타입으로 구성되어 있어 밸브(11')가 실린더벽(9')을The valve 11 'is constructed as a plunger type so that the valve 11' is connected to the cylinder wall 9 '

타고 원활하게 습동케 하기 위해서는 실린더벽(9')의 녹과 금속 이물질을 깨In order to smoothly ride, rust the metal wall of the cylinder wall (9 ')

끗이 제거한후 다시 코팅처리하는 등의 침판가공이 필수적으로 요구됨에 따It is essential that the needle plate processing such as coating treatment after removal of the cleaner is required

른 가공작업이 복잡하여 양산성의 문제점으로 지적되었을뿐 아니라 제품의In addition to being pointed out as a problem of mass production due to the complexity of other machining operations,

원가를 상승시키는 요인이 되었고,It was the factor that raised the cost,

또한 밸브(11')가 실린더벽(9')을 타고 습동하기 위해서도 밸브(11')의 외벽Further, in order for the valve 11 'to slide along the cylinder wall 9', the outer wall of the valve 11 '

과 실린더벽(9') 사이에 약간의 유격이 있어야 하므로 밸브(11')와 실린더벽Since there is a slight clearance between the valve 11 'and the cylinder wall 9'

(9') 사이에서 작동유체의 누설을 방지토록 하는 시일링에 대한 문제점이 있There is a problem with the sealing which prevents the leakage of the working fluid between the sealing rings 9 '

었다..

본 고안은 이러한 종래의 문제점을 해결하고자 고안된 것으로서 가공작업을The present invention has been devised to solve such a conventional problem,

대폭 줄여서 양산성에 따른 제조원가를 크게 절감시킴에 주목적이 있고 다른It is the main purpose to greatly reduce manufacturing cost due to mass production,

목적은 작동유체의 누설을 방지토록 하는 시일링성을 크게 향상시키려 함에The purpose is to greatly improve the sealing ability to prevent the leakage of the working fluid

그 특징이 있는 것이다.There is that feature.

이를 실현하기 위하여 본 고안은오일제트의 체크밸브 구조에 있어서, 밸브를In order to realize this, the present invention relates to a check valve structure of an oil jet,

플런저 타입에서 볼타입으로 대체하는 간단한 구조 개선으로 상기의 목적을The simple structure replacement by replacing the plunger type with the ball type has the above purpose

달성토록 하고 있다..
