Has In addition, the float 22 formed in the link structure moves up and down in accordance with the level of fuel in the cylinder.

봄베에 연료를 충전하거나 자동차의 구동으로 인해 연료가 소모됨에 따라 연료의 수위가 변화하고, 이에 따라, 플로트(22)가 상하 방향으로 이동하게 된다. 이때, 그 이동 거리에 따라 플로트(22)의 상측에 연결된 기어 연결부(60)의 기어가 회전하고, 기어 연결부(60)에 연결된 게이지 표시기(21)가 작동하여 봄베의 잔여 연료량 확인이 가능하도록 한다.As the fuel is consumed due to the fuel being charged to the cylinder or the driving of the vehicle, the level of the fuel changes, whereby the float 22 moves in the vertical direction. At this time, the gear of the gear connecting portion 60 connected to the upper side of the float 22 is rotated according to the movement distance, and the gauge indicator 21 connected to the gear connecting portion 60 is operated to check the remaining fuel amount of the bomb. .

이때, 기어 연결부(60)의 기어는 일정 범위만을 회전하여 플로트(22)가 최고 위치에 도달했을 때 더이상 회전하지 않도록 형성된다. At this time, the gear of the gear connecting portion 60 is formed so as not to rotate any more when the float 22 reaches the highest position by rotating only a certain range.

플로트(22)의 움직임에 따라 작동하는 기어 연결부(60)로부터 전달받은 위치는 게이지 표시기(21)에 나타나게 되며, 연료 충전시 설정해 놓은 최대 수위에 플로트(22)가 도달하여 기어 연결부(60)의 한계까지 회전하면, 체크밸브(40)를 작동시켜 유로가 차단되도록 한다.The position received from the gear connecting portion 60 which operates in accordance with the movement of the float 22 is displayed on the gauge indicator 21, and the float 22 reaches the maximum level set during the filling of the fuel so that the gear connecting portion 60 When rotating to the limit, the check valve 40 is activated to block the flow path.

상기와 같이 구성된 멀티밸브의 조립 및 작동상태를 설명하면 다음과 같다.Referring to the assembly and operation of the multi-valve configured as described above are as follows.

먼저, 원형의 베이스판(10)에 돌출되어 형성된 밸브블럭(11)의 옆측으로 연료가 주입되는 충진밸브(30)를 설치한다. First, the filling valve 30 is installed to the fuel injection to the side of the valve block 11 formed to protrude to the circular base plate 10.

한편, 베이스판(10)의 중앙부측에는 레벨게이지(20)를 설치한다. 레벨게이지(20)는 게이지 표시기(21)와 플로트(22)로 나누어지며, 베이스판(10)의 상측으로는 게이지 표시기(21)가 돌출되도록 설치되고, 베이스판(10)의 하측으로는 플로트(22)가 연결된다.On the other hand, the level gauge 20 is provided on the center side of the base plate 10. The level gauge 20 is divided into a gauge indicator 21 and a float 22. The gauge gauge 21 is provided so as to protrude from the upper side of the base plate 10, and the float below the base plate 10. 22 is connected.

여기서, 게이지 표시기(21)와 플로트(22)는 기어 연결부(60)를 통해 연결되어 봄베 내에 연료의 수위가 변함에 따라 상하고 움직일 수 있도록 한다.Here, the gauge indicator 21 and the float 22 are connected via the gear connection 60 to allow the fuel indicator to rise and move as the level of fuel in the cylinder changes.

연료 수위에 따라 움직이는 플로트(22)의 위치는 기어 연결부(60)의 작동에 의해 게이지 표시기(21)에 나타나게 되고, 기어 연결부(60)는 체크밸브(40)의 일측에 연결되어 플로트(22)의 위치를 체크밸브(40)에 전달할 수 있도록 한다.The position of the float 22 moving in accordance with the fuel level is displayed on the gauge indicator 21 by the operation of the gear connection 60, the gear connection 60 is connected to one side of the check valve 40 to float Allow the position of the check valve 40 to be transmitted.

상기와 같이 조립된 멀티밸브(1)는 봄베에 형성된 멀티밸브 장착홀(2')에 삽입되고, 멀티밸브 장착홀(2')보다 직경이 큰 베이스판(10)에 의해 봄베 내측으로 멀티밸브(1)가 전부 삽입되지 않도록 한다.The multi-valve 1 assembled as described above is inserted into the multi-valve mounting hole 2 'formed in the cylinder, and the multi-valve into the cylinder by the base plate 10 having a larger diameter than the multi-valve mounting hole 2'. Do not insert all of (1).

멀티밸브(1)는 베이스판(10)에 의해 멀티밸브 장착홀(2')에 걸쳐지게 되고, 멀티밸브(1) 외주면에 형성된 조립홈에 볼트를 삽입하여 조임으로써 봄베와 멀티밸브(1)가 고정되도록 한다.The multi-valve 1 is spread over the multi-valve mounting hole 2 'by the base plate 10, and the bolt and the multi-valve 1 are inserted by tightening the bolt into the assembling groove formed on the outer circumferential surface of the multi-valve 1. To be fixed.

멀티밸브(1)의 상면 일측에 설치된 충진밸브(30)를 통해 연료를 주입하고, 연료가 충전됨에 따라 봄베 내부의 연료 수위는 올라가게 되고, 자동차를 구동하여 연료를 소진하면 연료 수위는 내려가게 된다.Fuel is injected through the filling valve 30 installed at one side of the upper surface of the multi-valve 1, and as the fuel is charged, the fuel level inside the cylinder is increased, and when the fuel is exhausted by driving the vehicle, the fuel level is lowered. do.

레벨게이지(20)에 기어 연결부(60)로 연결된 플로트(22)는 봄베 내의 수위에 따라 상하로 움직이게 되고, 이에 따라 기어 연결부(60)의 기어가 회전하면서 연료의 수위를 게이지 표시기(21)에 전달하여 봄베 내의 연료 수위 상태가 표시되도록 한다.The float 22 connected to the level gauge 20 by the gear connecting portion 60 moves up and down according to the water level in the cylinder. Accordingly, as the gear of the gear connecting portion 60 rotates, the level of fuel is transferred to the gauge indicator 21. The fuel level in the cylinder.

레벨게이지(20)의 게이지 표시기(21)는 멀티밸브(1)의 상면에 설치되어 외부에서 게이지 표시기(21)의 확인이 가능하다.Gauge indicator 21 of the level gauge 20 is installed on the upper surface of the multi-valve (1) it is possible to check the gauge indicator 21 from the outside.

한편, 연료 충진시 연료 수위가 높아짐에 따라 플로트(22)의 위치가 상승하게 되고, 수위가 높아져 봄베의 한계에 도달하면, 봄베의 한계에 맞춰진 기어 연결부(60)의 회전 작동이 멈추게 된다. On the other hand, as the fuel level increases during fuel filling, the position of the float 22 rises, and when the water level rises to reach the limit of the bomb, the rotation operation of the gear connecting portion 60 that is set to the limit of the bomb stops.

그 후, 기어 연결부(60)의 회전이 더이상 진행되지 않고 기어 연결부(60)가 멈추면 작동하게 연결된 체크밸브(40)가 작동하여 유로를 차단함으로써 충진밸브(30)로의 공급이 차단되도록 한다.Thereafter, when the rotation of the gear connecting portion 60 does not proceed any more and the gear connecting portion 60 stops, the check valve 40 to be operated is operated to block the flow path so that the supply to the filling valve 30 is blocked.
