Description
본 발명은 차량에서의 오일 리저버 탱크로부터 오일이 캡을 통해 누유되는 것을 방지되도록 하는 오일 리킹 방지 장치에 대한 것이다.The present invention is directed to an oil leak prevention device that prevents oil from leaking through a cap from an oil reservoir tank in a vehicle.
차량에서의 오일 리저버 탱크는 주로 유압식 브레이크와 파워 스티어링 등에서 구비되는 오일 저장고로서, 여기에는 항상 일정량의 오일이 충진되도록 하여 유압형성에 필요한 오일이 안정적으로 각 작동부로 공급되도록 하고 있다.The oil reservoir tank in the vehicle is an oil reservoir mainly provided in hydraulic brakes and power steering, and the oil reservoir is always filled with a certain amount of oil so that the oil necessary for hydraulic pressure is stably supplied to each operating part.
한편 상기와 같은 오일은 작동부가 리턴시 공급된 오일을 오일 리저버 탱크로 재회수되도록 하고 있으므로 상기 오일 리저버 탱크에는 항상 적정량의 오일이 채워져 있게 된다.On the other hand, the oil as described above is to return the oil supplied to the oil reservoir tank when the operating unit returns to the oil reservoir tank is always filled with the appropriate amount of oil.
그러나 오일이 재회수될 때 오일 리저버 탱크에는 과도한 압력이 유도되면서 오일이 캡을 통해 외부로 누유가 되곤 하는데 특히 파워 스티어링에서의 풀 핸들링시에 자주 발생되면서 오일의 소모를 촉진하고, 엔진 룸내 오염을 가중시키게 되는 문제점이 있다.However, when oil is recollected, the oil reservoir tank leaks oil through the cap as excessive pressure is induced, especially during full handling in power steering, which promotes oil consumption and prevents contamination in the engine compartment. There is a problem that is weighted.
이에 상기한 문제점을 개선시키기 위하여 본 발명은 캡 직하부로 오일 주입은 원활하게 이루어지도록 하면서 일단 주입된 오일은 외부로 누유됨을 방지코자 하는데 목적이 있다.In order to improve the above problems, the present invention is intended to prevent oil from leaking to the outside while oil is injected smoothly under the cap.
상기한 목적을 달성시키기 위한 수단으로 본 발명은 상단부로는 환형의 재치부가 형성되고, 내주면 중간에는 걸림턱이 돌설되며, 오일탱크의 유입부 부근에 형성되는 케이스와, 리턴 스프링에 탄지된 상태로 케이스 내부에 설치되어 오일의 유입여부에 따라 상, 하 이동하여 오일의 리킹현상을 방지해주는 밸브를 포함하여 구성된 오일 리킹 방지장치에 있어서, 상기 케이스의 내주면에 형성된 걸림턱의 직하부 외주면으로는 오일이 통과할 수 있도록 유동부를 형성하면서 저면의 중심부에는 가이드가 천공되도록 하여 이 가이드에 안내되어 밸브가 상하 이동되도록 하되, 상기 유동부는 케이스의 중간 부분에 그 상,하부를 연결 지지하는 복수개의 서포트를 형성하여 구성되도록 한 것을 특징으로 하는 것이 특징이다.As a means for achieving the above object, the present invention has an annular mounting portion as an upper end portion, a locking jaw protrudes in the middle of the inner circumferential surface, and a case formed near the inlet portion of the oil tank, and supported by a return spring. An oil leak prevention device configured to include a valve installed inside the case to prevent oil leaking by moving up and down according to the inflow of oil. The flow is formed so that the flow can be passed through the guide in the center of the bottom to guide the guide so that the valve is moved up and down, the flow portion is provided with a plurality of supports for connecting the upper and lower parts to the middle portion of the case Characterized in that it is formed and configured.

이를 첨부한 실시예 도면을 참조하여 보다 상세하게 설명하면 다음과 같다.This will be described in more detail with reference to the accompanying drawings.
제1도는 본 발명에 따른 일실시예 단면 구조도로서, 도면부호 1은 케이스이다.1 is a cross-sectional structural view of an embodiment according to the present invention, wherein 1 is a case.
상기 케이스(1)는 전체적으로 원통형이며, 상단부는 외측방으로 연장시켜 오일 리저버 탱크의 오일 주입구 상단부에 안착이 될 수 있도록 환형의 재치부(11)를 이루고, 내주면 중간부에는 안쪽으로 돌출되게 걸림턱(12)이 돌설되도록 하며, 상기 걸림턱(12)의 직하부 외주면으로는 오일이 자유롭게 통과할 수 있는 유동부(13)를 형성토록 한다.The case 1 is generally cylindrical, and the upper end portion extends outward to form an annular mounting portion 11 so as to be seated at the upper end of the oil inlet port of the oil reservoir tank. (12) to protrude, and to the outer peripheral surface directly below the locking step 12 to form a flow portion 13 through which oil can pass freely.
오일이 통과할 수 있도록 한 상기 케이스(1)의 하부 유동부(13)는 제1도에서와 같이 복수개의 서포트(13A)로서 형성시킬 수도 있으나, 제2도에서와 같이 불순물 제거가 가능한 걸름망(14) 구조로도 할 수가 있어 외부로부터의 이물질 유입이 방지되도록 할 수가 있으며, 또한 저면에는 중앙에 가이드(15)가 형성되도록 한다.The lower flow portion 13 of the case 1 to allow oil to pass through may be formed as a plurality of supports 13A as shown in FIG. 1, but as shown in FIG. 14) It can also be a structure so that foreign matter from the outside can be prevented, and also the guide 15 is formed in the center on the bottom.
특히 상기한 케이스(1)의 내주면 걸림턱(12)은 제3도에서와 같이 상부는 외측에서 내측으로 완만하게 경사진 형상을 이루고, 하부는 외측에서 내측으로 호형의 상향 곡면으로서 형성되도록 하는 것이 보다 좋다.In particular, the inner circumferential surface engaging jaw 12 of the case 1 is formed such that the upper portion forms a gently inclined shape from the outside to the inside, as shown in FIG. 3, and the lower portion is formed as an arc-shaped upward curved surface from the outside to the inside. Better than
또한 상기한 케이스(1)의 저부에는 상기 가이드(15)에 삽입되는 승강부(21)와 상기 승강부(21)의 상단부로 케이스(1) 내주면 직경에 근접하여 확장되도록 한 상향 만곡진 헤드부(22)가 일체로 형성되도록 한 버섯형상의 밸브(2)가 축설된다.In addition, the bottom portion of the case 1 is an upward curved head portion which is extended to be close to the inner circumferential surface diameter of the case 1 to the elevating portion 21 inserted into the guide 15 and the upper end of the elevating portion 21. A mushroom valve 2 is formed so that the 22 is integrally formed.
상향으로 만곡지게 되는 헤드부(22)는 상부로부터 유입되는 오일이 그 즉시 바깥측으로 흘러 내리도록 하기 위한 것이며, 특히 상기 헤드부(22)는 상승시 케이스(1)의 내주면으로 돌설시킨 걸림턱(12)에 걸려지면서 이상 상승되지 못하도록 하는 직경으로 형성되도록 한다.The head portion 22 which is curved upward is to allow the oil flowing from the upper portion to immediately flow outward, and in particular, the head portion 22 has a locking jaw protruding to the inner circumferential surface of the case 1 when raised. 12) It is to be formed to a diameter so as not to rise over the hook.
한편 상기 케이스(1)의 가이드(15)을 따라 상하 슬라이딩 작동되는 밸브(2)의 승강부(21) 외주면으로는 리턴 스프링(3)이 탄설되도록 하여 상부로부터 오일 중력이 제거되면 밸브(2)를 상승시켜 헤드부(22)가 케이스(1)의 걸림턱(12)에 걸려질 수 있도록 한다.On the other hand, the return spring 3 is coalesced on the outer circumferential surface of the elevating portion 21 of the valve 2 that is vertically sliding along the guide 15 of the case 1 so that the oil gravity is removed from the upper side of the valve 2. By raising the head portion 22 to be caught on the locking step 12 of the case (1).
이같은 구성에 따른 본 발명의 작용을 살펴보면 제4도에서 보는 바와 같이 오일이 오일 리저버 탱크(4)의 주입구(41) 상부로부터 주입이 되면 오일의 중량과 떨어지는 압력에 의해서 걸림턱(12)에 걸려져 있던 밸브(2)가 하강을 하게 된다.Looking at the operation of the present invention according to such a configuration as shown in Figure 4 when the oil is injected from the upper portion of the inlet 41 of the oil reservoir tank 4 is caught on the locking jaw 12 by the weight of the oil and the falling pressure The closed valve 2 descends.
밸브(2) 하강시 리턴 스프링(3)은 압축이 되면서 헤드부(22)는 걸림턱(12)으로부터 이격되고, 승강부(21)는 가이드(15)을 따라 하향 슬라이딩 작동하게 되는 바 이 같은 밸브(2) 작동에 따라 헤드부(22) 상부의 외측으로 유동부(13) 면적이 확장되면서 오일이 탱크내로 원활하게 유입이 된다.When the valve 2 is lowered, the return spring 3 is compressed and the head 22 is spaced apart from the locking jaw 12, and the lifting portion 21 is slid downward along the guide 15. According to the operation of the valve 2, the area of the flow part 13 is extended to the outside of the upper part of the head part 22, and oil is smoothly introduced into the tank.
주입되는 오일이 일정 위치에 도달하면 오일 공급을 중단하게 되고, 이 때 상부로부터의 오일 중력이 제거되면서 밸브(2)는 리턴 스프링(3)에 의해서 상승하게 되고, 급기야는 밸브(2)의 헤드부(22) 외측단 주연부가 케이스(1)의 걸림턱(12)에 밀착되므로서 오일 통로를 차단시키게 된다.When the injected oil reaches a certain position, the oil supply is stopped. At this time, the oil gravity from the upper portion is removed and the valve 2 is lifted by the return spring 3, and the air is supplied to the head of the valve 2. The outer periphery of the outer portion 22 is in close contact with the locking step 12 of the case 1 to block the oil passage.
따라서 외부로부터의 이물질이 헤드부(22)에 걸려지면서 더 이상의 유입이 방지되며, 주입된 오일은 걸림턱(12)에 걸려진 밸브 헤드부(22)에 의해서 누유가 방지되게 된다.Therefore, the foreign matter is caught on the head portion 22, the further inflow is prevented, and the injected oil is prevented from leaking by the valve head portion 22 caught on the locking jaw (12).
특히 오일 리저버 탱크(4)내 압력이 상승하면 할수록 밸브(2)의 상승력은 커지면서 헤드부(22)와 걸림턱(12)간 밀착력이 강화되므로 더욱 강력한 오일의 리킹을 방지시킬 수가 있게 된다.In particular, as the pressure in the oil reservoir tank 4 rises, the lifting force of the valve 2 increases, and thus the adhesion between the head portion 22 and the locking jaw 12 is strengthened, thereby preventing the leakage of more powerful oil.
그러므로 본 발명에 따른 작동 구조에 의해 탱크(4)내 오일의 역류 및 누유를 차단시키므로서 엔진 룸의 오염을 예방하고, 특히 불필요한 오일 소모를 방지시켜 보다 경제적이면서 청결한 오일 관리가 이루어지도록 하는 매우 유용한 효과가 있게 되는 것이다.Therefore, the operating structure according to the present invention prevents contamination of the engine room by blocking backflow and leakage of oil in the tank 4, and in particular, it is very useful to prevent unnecessary oil consumption and to achieve more economical and clean oil management. It will work.
