본 고안은 자동차나 중장비 등의 원동기 연료탱크에 복착되는 캡에 관한 것이다.The present invention relates to a cap that is worn on the prime mover fuel tank, such as automobiles and heavy equipment.

종래 이런 종류의 캡은 단순히 연료탱크의 연료주입구에 형성된 나사부에 패킹을 개재하여 밀폐하는 것이었으므로 연료가 소모됨에 따라 탱크내에 그 소모량만큼의 부압이 발생되므로 연료공급이 원활하지 못하게 되어 원동기 성능이 저하되는 폐단이 있었다.Conventionally, this type of cap was simply sealed through a threaded portion formed in the fuel inlet of the fuel tank through the packing. As the fuel is consumed, the negative pressure is generated as much as the consumption of the fuel, so the fuel supply is not smooth and the motor performance is improved. There was a deterioration.

또한 이러한 폐단을 제거하기 위하여 캡의 상면에 통기공을 천설하므로써 부압발생을 방지하는 것이 있었으나, 이 또한 통기공을 통해 먼지 등의 이물질이 혼입되어 연료계통의 고장을 유발시키게 되는 폐단이 있었다.In addition, by removing a vent hole on the upper surface of the cap to remove such a waste end to prevent the occurrence of negative pressure, but also there was a lung end that causes the fuel system failure by mixing foreign matters such as dust through the vent hole.

따라서 본 고안은 이러한 종래의 제반 폐단을 제거하기 위하여 안출된 것으로 이를 첨부도면에 따라서 상세히 설명하면 다음과 같다.Therefore, the present invention has been devised to remove such a conventional closed end described in detail according to the accompanying drawings as follows.

즉 본 고안은 도시한 바와같이, 연료탱크(1)의 주입구 나사부(2)에 나합되는 통상의 연료탱크 캡에 있어서, 외면과 나사부(3)사이의 저면에 다수의 공기유입구(4)를 천설하여 통공(5)으로 탱크(1)의 내부공간과 연통시키고, 연통공(5)의 내주면에 원통형 여과부재(6)를 감착하여 다수의 통공(7)의 천설된 고정판(8)로써 고정하여서 된 것이다.That is, the present invention, as shown, in the conventional fuel tank cap screwed to the inlet screw portion 2 of the fuel tank 1, a plurality of air inlet (4) is laid on the bottom surface between the outer surface and the screw portion (3) Communicate with the inner space of the tank 1 through the through hole (5), the cylindrical filtration member 6 is attached to the inner circumferential surface of the communication hole (5) and fixed by the installed fixed plate (8) of the plurality of through holes (7) It is.

미설명부호(9)는 고정판(8)을 캡에 부착하기 위한 고정나사이며, (10)은 패킹이다.Reference numeral 9 is a fixing screw for attaching the fixing plate 8 to the cap, and 10 is a packing.

이와같이 구성된 본 고안은 제2도와 같이 연료탱크(1)의 주입구 나사부(2)에 나합하여 사용하는 것인바, 상기 공기유입구(4)가 연료주입구 외부에 위치하게 되므로 연료가 소모되드라도 그 소모량만큼 필요로 하는 공기가 공기유입구(4)로부터 통공(5)을 통해 여과부재(6)에 의해 여과되어 탱크(1)내로 유입되므로 탱크(1)내에는 부압이 발생되는 일없이 항상 대기압을 유지하게 되는 것이다.The present invention configured as described above is to be used in combination with the inlet screw portion 2 of the fuel tank 1 as shown in FIG. 2, since the air inlet 4 is located outside the fuel inlet, as much as the consumption amount of the fuel is consumed. Since the required air is filtered by the filtration member 6 from the air inlet 4 through the through hole 5 and flows into the tank 1, the tank 1 always maintains atmospheric pressure without generating negative pressure. Will be.

따라서 본 고안에 의하여 연료가 소모되드라도 탱크내에 부압이 발생되는 일이 없으므로 연료공급이 항상 원활하게 이루어지며, 또한 공기유입구(4)를 통해 유입되는 공기는 여과부재(6)에 의해 여과되어 신선한 공기만이 유입되므로 먼지 등의 이물의 혼입이 방지되어 연료계통의 기능고장 등이 발생할 염려가 없는 등 실용상 많은 효과가 있는 것이다.Therefore, even if the fuel is consumed by the present invention, since no negative pressure is generated in the tank, fuel supply is always smoothly performed, and the air introduced through the air inlet 4 is filtered by the filtering member 6 and is fresh. Since only the air is introduced, foreign matters such as dust are prevented from being mixed, so that there is no fear of malfunction of the fuel system.
