Description

자동차용 연료탱크의 롤오버체크밸브 소음개선 구조{noise improvement strukture of rollover-check valve in fuel tank for automobile} Noise improvement strukture of rollover-check valve in fuel tank for automobile}

본 발명은 자동차용 연료탱크의 롤오버체크밸브 소음개선 구조에 관한 것으로서, 더욱 상세히는 자동차가 주행중 요철 형태의 도로나 과속방지턱 등을 지날때 발생되는 진동에 의해 연료탱크내에 설치된 롤오버체크밸브의 플로우어셈블리가 유동 되더라도 소음이 발생되지 않도록 함으로써 탑승자의 승차감을 향상시켜 줄 수 있도록 한 자동차용 연료탱크의 롤오버체크밸브 소음개선 구조에 관한 것이다.The present invention relates to a noise improvement structure of a rollover check valve of a fuel tank for an automobile, and more particularly, a flow assembly of a rollover check valve installed in a fuel tank by vibration generated when a vehicle passes an uneven road or an overspeed bump. This invention relates to a rollover check valve noise improvement structure of a fuel tank for an automobile, which can improve passenger comfort by preventing noise from being generated even when the fuel is flowed.

일반적으로 자동차는 가솔린 또는 경유와 같은 연료를 엔진에서 연소시킬 때 발생하는 연소열과 폭발력을 이용하여 구동하는 것이므로 차체의 저면부에 연료탱크를 설치한 후 연료를 연료탱크에 저장한 상태에서 연료를 엔진에 일정량을 공급하게 된다.In general, automobiles are driven by the combustion heat and explosive power generated when the fuel, such as gasoline or diesel, is burned in the engine. Therefore, after the fuel tank is installed at the bottom of the vehicle body, the fuel is stored in the fuel tank. It will supply a certain amount to.

즉, 자동차의 연료장치는 연료탱크, 연료주유파이프, 연료펌프로 구성되는데 연료탱크는 강판으로 만들고 내부에는 연료의 출렁임을 방지함과 동시에 강성과 강도를 높이기 위한 베플플레이트가 설치되어 있으며, 주석 또는 아연도금을 하여 방청처리되어 있으며 탱크의 용량은 1일 소요량을 기준하기 때문에 배기량이 클수록 크다.In other words, the fuel device of an automobile is composed of a fuel tank, a fuel lubrication pipe, and a fuel pump. The fuel tank is made of steel sheet, and a baffle plate is installed inside the tank to prevent swelling of fuel and to increase rigidity and strength. It is galvanized and rust prevented, and the capacity of the tank is based on the daily requirement, so the larger the exhaust volume is.

그리고 연료주유파이프는 연료의 통로로서 25-42mm의 지름으로 스테인레스 또는 강제의 파이프로 연료계통의 파이프를 서로 연결하며 연결부는 클램프로 조이고, 연료주유파이프에는 연료주유파이프를 개폐하기 위한 캡이 착탈가능하게 설치되며, 차체 외부에는 캡과 연료주유파이프를 외부로 부터 개폐하기 위한 도어가 힌지를 매개로 회동 가능하게 설치된다.In addition, the fuel oil supply pipe connects the fuel system pipes to each other by stainless steel or steel pipe with a diameter of 25-42 mm as a fuel passage, and the connection part is tightened by a clamp, and a cap for opening and closing the fuel oil supply pipe is removable. It is installed to the outside of the vehicle body, the door for opening and closing the cap and fuel oil supply pipe from the outside is installed so as to rotate through the hinge.

또한, 연료펌프는 DC모터로 축전지 전원을 공급받아 구동되어 연료탱크에 저장되어 있는 연료를 인젝터에 공급하는 것으로 종류에는 엔진룸에 설치되는 외장형과 연료탱크내에 설치되는 내장형이 있으나 연료펌프의 소음을 억제하고 베이퍼로크 및 연료의 맥동을 방지하는 내장형이 많이 사용된다.In addition, the fuel pump is powered by a battery powered by a DC motor to supply the fuel stored in the fuel tank to the injector. There are two types of fuel pumps: an external type installed in the engine room and an internal type installed in the fuel tank. The built-in type which suppresses and prevents pulsation of vapor lock and fuel is used a lot.

그리고 연료탱크내에는 롤오버체크밸브(ROLLOVOVER CHECKVALVE)를 설치하여 자동차가 전복시 롤오버체크밸브에 의하여 연료탱크내의 연료가 외부로 누출되는 것을 방지토록 하는 것이나 종래 롤오버체크밸브는 많은 문제점이 있는 것으로서 이를 상세히 설명하면 다음과 같다.In addition, a rollover check valve is installed in the fuel tank to prevent the leakage of fuel in the fuel tank to the outside by the rollover check valve when the vehicle is rolled over. However, the conventional rollover check valve has many problems. The explanation is as follows.

즉, 도 1 내지 도 2에서와 같이 연료탱크(도면중 미도시)내에 설치되는 롤오버체크밸브(20)는 체크밸브 기능이 구비된 플로트어셈블리(21)를 롤오버체크밸브케이스(22)에 내장하고, 플로트어셈블리(21)가 롤오버체크밸브케이스(22)내에서 이탈되는 것을 방지하기 위하여 플로트어셈블리(21)를 받쳐주는 받침플레이트(23)를 롤오버체크밸브케이스(22)와 결합되게 설치한다.That is, the rollover check valve 20 installed in the fuel tank (not shown in FIG. 1) as shown in FIGS. 1 to 2 includes a float assembly 21 having a check valve function in the rollover check valve case 22. In order to prevent the float assembly 21 from being detached from the rollover check valve case 22, the support plate 23 supporting the float assembly 21 is installed to be combined with the rollover check valve case 22.

그런데 자동차가 주행중 요철 형태의 도로나 과속방지턱 등과 같이 도로사정이 좋지 않은 곳을 지날갈때 진동이 발생되는데 이 진동이 롤오버체크밸브(20)에 전달되면서 플로트어셈블리(21)가 유동되는 것으로 즉, 플로트어셈블리(21)는 단순히 롤오버체크밸브케이스(22)내에 끼워진 상태에서 그 저면을 받침플레이트(23)가 받쳐 이탈됨을 방지하는 것이므로 종래에는 진동이 전달되면 플로트어셈블리(21)가 롤오버체크밸브케이스(22)내에서 유동되면서 받침플레이트(23)와 접촉되어 소음이 발생되는 것이고, 그 소음은 자동차의 실내로 까지 그대로 전달되어 탑승자들의 승차감을 떨어뜨리는 문제점이 있었다.
By the way, when the car passes a place where road conditions are not good, such as uneven road or speed bump while driving, the vibration is transmitted to the rollover check valve 20, that is, the float assembly 21 flows, that is, float. Since the assembly 21 is simply inserted into the rollover check valve case 22 to prevent the support plate 23 from being detached from the bottom, the float assembly 21 is rollover check valve case 22 when vibration is transmitted. There is a problem that the noise is generated in contact with the backing plate 23 while flowing in the), the noise is transmitted to the interior of the car as it is to reduce the ride comfort of the occupants.

이에 본 발명은 이와 같은 종래의 문제점을 해결하기 위한 것으로 본 발명의 목적은 자동차가 도로사정이 좋지 않은 요철 형태의 도로나 과속방지턱 등을 지날때 발생되는 진동으로 인하여 롤오버체크밸브를 구성하는 플로트어셈블리가 유동 되더라도 소음이 방지되어 탑승자의 승차감을 향상시킬 수 있도록 한 자동차용 연료탱크의 롤오버체크밸브 소음개선 구조를 제공하기 위한 것이다.

이와 같이 본 발명은 자동차용 연료탱크(100)의 내부에 설치되어 차량 전복시 연료의 외부 유출을 방지하는 롤오버체크밸브(200)를 구성함에 있어서, 체크밸브 기능이 구비된 플로트어셈블리(210)와; 플로트어셈블리(210)를 보호하기 위해 플로트어셈블리(210) 위에서 외부에 씌워지며, 외주면에는 거치용 브라켓결합부(221)가 구비되고, 상부에는 호스연결구가 구비된 롤오버체크밸브케이스(220)와; 롤오버체크밸브케이스(220) 하부에 조립되며, 플로트어셈블리(210)를 받쳐서 이탈됨을 방지하는 받침플레이트(230)와; 플로트어셈블리(210)와 받침플레이트(230) 사이에 설치되어 플로트어셈블리(210)를 탄력적으로 받쳐주면서 진동을 흡수하는 쿠션플레이트(240)로 구성된 것을 특징으로 한다.As described above, the present invention provides a float assembly 210 having a check valve function in forming a rollover check valve 200 installed inside the fuel tank 100 for automobiles to prevent external leakage of fuel when the vehicle is overturned. ; Covered to the outside on the float assembly 210 to protect the float assembly 210, the outer peripheral surface is provided with a mounting bracket coupling portion 221, the upper rollover check valve case 220 is provided with a hose connector; A support plate 230 which is assembled under the rollover check valve case 220 and supports the float assembly 210 to prevent it from being separated; It is installed between the float assembly 210 and the support plate 230 is characterized by consisting of a cushion plate 240 for absorbing vibration while supporting the float assembly 210 elastically.

도면중 미설명 부호 (222)는 롤오버체크밸브케이스에 형성된 다수의 결합편이고, (231)은 결합편이 끼워질 수 있도록 받침플레이트에 형성된 결합공이다.In the drawings, reference numeral 222 denotes a plurality of coupling pieces formed in the rollover check valve case, and 231 is a coupling hole formed in the support plate so that the coupling pieces can be fitted.

이러한 본 발명은 자동차가 전복시 연료탱크(100)내의 연료가 외부로 유출되는 것을 방지하기 위하여 롤오브체크밸브케이스(220), 플로트어셈블리(210), 받침플레이트(230)로 이루어진 롤오버체크밸브(200)를 연료탱크(100)내에 설치하는 것은 종래와 마찬가지이다.The present invention is a rollover check valve consisting of a roll of check valve case 220, a float assembly 210, the backing plate 230 to prevent the fuel in the fuel tank 100 is leaked to the outside when the vehicle is rolled over ( The installation in the fuel tank 100 is the same as in the prior art.

즉, 롤오버체크밸브(200)는 롤오버체크밸브케이스(220)내에 플로트어셈블리(210)를 끼운후 플로트어셈블리(210)가 이탈되는 것을 방지하기 위하여 받침플레이트(230)를 플로트어셈블리(210)저면에 받친 상태에서 롤오버체크밸브케이스(220)에 밀착시켜 롤오버체크밸브케이스(220)에 형성된 결합편(222)이 받침플레이트(230)의 결합공(231)에 끼워지게 하여서 플로트어셈블리(210)의 이탈을 방지토록 한 상태에서 롤오버체크밸브(200)를 롤오버체크밸브케이스(220)에 구비된 브라켓결합부(221)에 의해 연료탱크(100)내에 설치되게 한 것이다.That is, the rollover check valve 200 inserts the float assembly 210 into the rollover check valve case 220 and then supports the support plate 230 on the bottom of the float assembly 210 to prevent the float assembly 210 from being separated. The float assembly 210 may be detached from the support plate 231 of the support plate 230 by fitting the coupling piece 222 formed on the rollover check valve case 220 in close contact with the rollover check valve case 220. The rollover check valve 200 is to be installed in the fuel tank 100 by the bracket coupling part 221 provided in the rollover check valve case 220 in the state to prevent this.

그러나 본 발명에서의 특징은 자동차가 도로사정이 좋지 않은 요철 형태의 도로나 과속방지턱 등을 주행시 발생되는 진동에 의해 롤오버체크밸브(200)의 구성 부품인 플로트어셈블리(210)가 롤오버체크밸브케이스(220)내에서 유동 되더라도 소음이 발생되지 않도록 하여 탑승자의 승차감을 향상시킬 수 있도록 한 것이다.However, the present invention is characterized in that the float assembly 210, which is a component of the rollover check valve 200 due to the vibration generated when the vehicle travels on uneven roads or speed bumps, etc., in which the road condition is not good, the rollover check valve case ( Even if it flows within 220, the noise is not generated so that the passenger's riding comfort can be improved.

즉, 본 발명은 별도의 쿠션플레이트(240)를 구비하여 플로트어셈블리(210)와 받침플레이트(230)사이에 쿠션플레이트(240)를 설치하였다.That is, the present invention has a separate cushion plate 240 to install a cushion plate 240 between the float assembly 210 and the support plate 230.

여기서 쿠션플레이트(240)는 받침플레이트(230)를 롤오버체크밸브케이스 (220)와 결합하기 전에 플로우어셈블리(210)와 받침플레이트(230)에 사이에 끼워지게 한 후 받침플레이트(230)와 롤오버쿠션체크밸브케이스(220)를 서로 결합 함으로써 이탈되지 않는다.Here, the cushion plate 240 is sandwiched between the flow assembly 210 and the support plate 230 before the support plate 230 is coupled to the rollover check valve case 220, and then the support plate 230 and the rollover cushion.
