본 발명은 엘피엘아이 연료장치의 연료 리턴 소음 저감장치에 관한 것으로, 더 상세하게는 연료탱크에서 연료펌프를 통하여 송출된 액상연료가 압력조절기 인젝터에서 분사되고, 남은 연료는 압력조절기와 리턴파이프등을 지나서 연료탱크로 다시 이송됨에 있어, 배출밸브에 액상연료와 기상연료의 배출공을 각각 형성하여 배출되게 함으로서 액상연료와 기상연료 간의 트러블에 의한 소음을 저감시킬 수 있는 장치에 관한 것이다.The present invention relates to a fuel return noise reduction device of an LP fuel device, more specifically, the liquid fuel sent through the fuel pump in the fuel tank is injected from the pressure regulator injector, the remaining fuel is a pressure regulator and return pipe, etc. The present invention relates to a device capable of reducing noise caused by trouble between liquid fuel and gaseous fuel by passing through the fuel tank again to form a discharge hole of liquid fuel and gaseous fuel in a discharge valve.

종래의 제품은 리턴 연료의 배출공이 하나로 되어 있어, 액상연료와 기상연료가 동시에 배출공을 빠져나가며 서로 간섭 트러블이 발생하며 소음이 나게되는 문제점이 있었다.Conventional products have one discharge hole of the return fuel, liquid fuel and gaseous fuel exits the discharge hole at the same time, there is a problem that the interference occurs and noise occurs.

본 발명은 이상과 같은 문제점을 해결하기 위하여 안출된 것으로, 본 발명의 목적은 연료 리턴 파이프의 선단부에 챔버1 및 2로 간벽이 형성되고 액상연료와 기상연료가 각각 분리 배출될 수 있는 배출공이 형성된 배출배브를 연결, 제공함에 있다. The present invention has been made in order to solve the above problems, an object of the present invention is formed in the front end of the fuel return pipe chamber 1 and 2 is formed with a discharge hole to separate and discharge the liquid fuel and gaseous fuel, respectively It is to connect and provide the discharge barb.

이와 같은 목적을 달성하기 위하여, 엘피엘아이 방식에 있어, 리턴 연료파이프의 선단부에 장치된 밸브내에 챔버1과 챔버2로 구획된 격벽을 형성하고, 상기 챔버1의 하방에는 액상연료가, 상기 격벽의 관통공을 통하여 챔버2의 상부에는 기상연료가 각각 배출될 수 있는 배출공이 형성되어 있는 것을 특징으로 한다.In order to achieve the above object, in the LPLP method, a partition partitioned into chamber 1 and chamber 2 is formed in a valve provided at the front end of the return fuel pipe, and liquid fuel is provided below the chamber 1, and the partition wall is formed. The upper part of the chamber 2 through the through hole of the gas is characterized in that the discharge hole is formed to discharge the fuel.

이하, 본 발명을 첨부된 도면에 의해 상세히 설명하면 다음과 같다.Hereinafter, described in detail by the accompanying drawings of the present invention.

도 2는 본 발명의 리턴연료를 분리배출 상태를 나타낸 도면이고, 도 3 및 도 4는 본 발명이 적용되어 사용 상태를 나타낸 도면이다.2 is a view showing a separated discharge state of the return fuel of the present invention, Figures 3 and 4 is a view showing a use state to which the present invention is applied.

상기 도시된 바와 같이, 엘피엘아이 방식 엔진의 연료공급에 있어, 연료탱크(11)내로 연결되어 있는 리턴 연료파이프(12)의 선단부에 밸브를 장치함에 있어서, 밸브(10)내에 챔버1(13)과 챔버2(13')로 구획되는 격벽(14)이 형성되어 있고, 상기 챔버1(13)의 하부에는 액상연료를 배출할 수 있는 배출공(15)이 형성되어 있으며, 상기 격벽(14)에 형성된 관통공(16)을 통한 상기 챔버2(13')의 상부에는 기상연료를 배출할 수 있는 배출공(15')이 형성되어 있는 구조로 구성되어 있다.As shown above, in the fuel supply of the LLP engine, in the valve 10 at the distal end of the return fuel pipe 12 connected to the fuel tank 11, the chamber 1 (13) in the valve (10) ) And a partition wall 14 partitioned into chamber 2 (13 '), and a discharge hole 15 for discharging liquid fuel is formed in the lower part of the chamber 1 (13), and the partition wall 14 The upper part of the chamber 2 (13 ') through the through hole 16 formed in the) is configured to have a structure in which the discharge hole (15') for discharging the gas phase fuel is formed.

또한, 상기 격벽(14)의 하면에는 안내벽(14')이 하부를 향하여 돌출된 구조로 구성되어 이루어져 있다.In addition, the lower surface of the partition 14 is composed of a structure in which the guide wall 14 'protrudes downward.

이와 같이 구성된 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above is as follows.

엘피엘아이 엔진 방식의 연료공급에 있어, 연료탱크에 저장된 엘피지 액상연료를 연료펌프를 사용하여 송출하면, 송출된 액상연료는 압력조절기 인젝터에서 분사되고, 남은 연료는 압력조절기와 리턴파이프 등을 지나서 연료탱크로 다시 이송된다. In LP fueled engine supply, when the liquid fuel stored in the fuel tank is discharged using the fuel pump, the discharged liquid fuel is injected from the pressure regulator injector, and the remaining fuel passes through the pressure regulator and the return pipe. It is transferred back to the fuel tank.

이때, 상기 리턴연료는 연료파이프(12)의 선단부에 연결, 장치된 밸브(10)내에서 격벽(14)과 안내벽(14')에 의해 안내되어 액상연료는 챔버1(13)의 하부 배출공(15)을 통하여 배출되게 하고, 기상연료는 상기 격벽(14)의 관통공(16)을 통하여 챔버2(13')의 상부에 형성된 배출공(15')으로 배출되도록 안내됨으로서, 액상연료와 기상연료를 분리하여 배출되도록 한 것이다.At this time, the return fuel is connected to the distal end of the fuel pipe 12 and guided by the partition 14 and the guide wall 14 'in the valve 10 installed so that the liquid fuel is discharged from the lower portion of the chamber 1 13. It is discharged through the ball 15, the gaseous fuel is guided to be discharged to the discharge hole 15 'formed in the upper portion of the chamber 2 (13') through the through hole 16 of the partition 14, liquid fuel And gaseous fuel are separated and discharged.

본 발명은 이상에서 설명된 바와 같이, 리턴되는 연료를 배출 밸브내에서 액상연료와 기상연료를 각각 안내하여 분리 배출되게 하므로서 액상연료와 기상연료가 함께 배출되면서 상호 간섭 트로블로 파열음이 발생되었던 소음을 저감시킬 수 있는 효과가 있다.As described above, the returned fuel is discharged by guiding the liquid fuel and the gaseous fuel separately in the discharge valve, respectively, so that the liquid fuel and the gaseous fuel are discharged together, thereby generating a noise in which the bursting noise is generated by mutual interference. There is an effect that can be reduced.
