Abstract

PURPOSE: A fuel inflow device of a fuel pump is provided to make fuel come into a fuel reservoir by forming an inlet portion at the bottom of a fuel pump and prevent fuel from being discharged to the outside by connecting a check valve to the fuel pump. CONSTITUTION: A fuel inflow device of a fuel pump(10) has an inlet portion(20), and a check valve(30) installed to the inlet portion, to prevent the incoming fuel from being discharged. The inlet portion is formed at the bottom surface of a fuel reservoir(11) of the fuel pump so that fuel can come into the fuel reservoir. Accordingly, the discharge quantity of the fuel pump is reduced and thus, temperature of fuel in a fuel tank is reduced, and evaporation gas is reduced.

Description

연료펌프의 연료유입장치{apparatus fuel-inflow of fuel-pump}Apparatus fuel-inflow of fuel-pump}

본 발명은 연료펌프의 연료유입장치에 관한 것으로서, 더 자세하게는 연료펌프의 아래에 유입부를 형성시켜 연료저장기내로 유입될 수 있도록 하고 체크밸브를 연결하여 외부로 연료가 배출되는 것을 방지할 수 있는 연료펌프의 연료유입장치에 관한 것이다.The present invention relates to a fuel inlet device of a fuel pump, and more particularly, to form an inlet portion below the fuel pump to be introduced into the fuel reservoir and to connect the check valve to prevent the fuel from being discharged to the outside. It relates to a fuel inlet device of a fuel pump.

일반적으로 현재 사용되는 가솔린차량은 연료탱크 내에 연료펌프를 장착하여 펌프를 구동시켜 엔진으로 공급하고 엔진에서 사용하고 남은 연료를 연료탱크로 다시 되돌리는 구조로 되어 있다.In general, the gasoline vehicle currently used has a structure in which a fuel pump is installed in a fuel tank to drive a pump to supply the engine, and return the remaining fuel used in the engine to the fuel tank.

최근에는 모듈방식의 연료펌프를 사용하고 있는데 이는 리턴되어 연료를 이용하여 제트펌프를 구동시켜 연료탱크내로 연료를 유입시킨다. 이때 제트 펌프를구동시키기 위해 차량의 연료소모량 대비 추가로 40L/Hr정도의 연료가 필요하게 된다. 따라서, 차량 실소요량 대비 고유량의 모터를 사용해야 된다.Recently, a modular fuel pump is used, which is returned and drives the jet pump using fuel to inject fuel into the fuel tank. In this case, 40L / Hr of fuel is needed in addition to the fuel consumption of the vehicle to drive the jet pump. Therefore, a high flow rate motor must be used relative to the actual vehicle demand.

그러나, 종래의 가솔린차량은 차량의 실소요량에 제트펌프를 구동을 우ㅐㅣ한 추가 연료공급을 위해 고성능의 모터를 필요로 하므로 추가적인 비용의 증가를 가져오게 된다.However, conventional gasoline vehicles require a high-performance motor to supply additional fuel to drive the jet pump to the actual demand of the vehicle, resulting in an additional cost increase.

여기서, 차량 주행시 고유량의 연료를 엔진으로 계속해서 송출함으로써 연료탱크 내에 연료온도가 추가적으로 2~3℃ 상승된다. 이는 연료탱크 내에서 발생디는 증발가스의 량을 증가시켜 결과적으로는 캐니스터의 용량증개를 요구하게 된다.Here, the fuel temperature in the fuel tank is further increased by 2 to 3 ° C by continuously sending a high flow fuel to the engine when the vehicle is running. This increases the amount of boil-off gas generated in the fuel tank and consequently requires the canister to increase its capacity.

본 발명은 이와 같은 종래의 제반 문제점을 해결하기 위한 것으로서 그 목적은 연료펌프의 아래에 유입부를 형성시켜 연료저장기내로 유입될 수 있도록 하고 체크밸브를 연결하여 외부로 연료가 배출되는 것을 방지할 수 있도록 하는 데 있다.The present invention is to solve such a conventional problem as its purpose is to form an inlet portion below the fuel pump to be introduced into the fuel reservoir and to connect the check valve to prevent the discharge of fuel to the outside To help.

도 1은 본 발명의 실시예에 따른 연료펌프의 연료유입장치에 관한 것이다.1 relates to a fuel inlet device of a fuel pump according to an embodiment of the present invention.

본 발명은 연료펌프 내부로 연료가 유입되면서 외부로 배출되는 것을 방지할 수 있도록 하는 장치에 관한 것으로서, 도 1에서 보는 바와 같이 연료펌프(10)의 연료저장기(11) 하면에 형성되어 연료가 상기 연료저장기(11) 내부로 유입될 수 있도록 하는 유입부(20)와, 상기 유입부(20)에 설치되어 유입된 연료가 외부로 배출되는 것을 방지하는 체크밸브(30)가 연결되는 구성을 갖는다.The present invention relates to a device for preventing fuel from being discharged to the outside while the fuel is introduced into the fuel pump. As shown in FIG. The inlet part 20 to be introduced into the fuel reservoir 11 and the check valve 30 which is installed in the inlet part 20 to prevent the inlet fuel is discharged to the outside is connected Has

이와 같이 구성되는 본 발명의 작용효과를 설명하면 다음과 같다.Referring to the effects of the present invention configured as described above are as follows.

본 발명은 연료펌프 내부로 연료가 유입되면서 외부로 배출되는 것을 방지할 수 있도록 하는 장치에 관한 것으로서, 도 1에서 보는 바와 같이 연료저장기(11) 하면에 약10[mm]정도의 구멍이 형성된 유입부(20)에 체크밸브(30)를 장착하여 연료펌프(10) 외부로 빠지는 것을 방지시킨다.The present invention relates to an apparatus for preventing fuel from being discharged to the outside while the fuel is introduced into the fuel pump. As shown in FIG. 1, a hole of about 10 [mm] is formed in the lower surface of the fuel reservoir 11. The check valve 30 is mounted on the inlet 20 to prevent the fuel pump 10 from falling out.

여기서, 연료펌프(10)가 연료저장기(11) 내의 연료를 엔진으로 송출하게 되면 연료탱크내에 있는 유면보다 연료저장기(11) 내의 연료유면이 낮아지게 된다.Here, when the fuel pump 10 delivers the fuel in the fuel reservoir 11 to the engine, the fuel oil level in the fuel reservoir 11 is lower than the oil level in the fuel tank.

이때 연료탱크측의 압력이 연료저장기(11) 측 보다 높아지기 때문에 고무부재등을 밀어 올리고 연료가 연료탱크에서 연료저장기(11)로 흘러 들어가게 된다. 이후 연료탱크와 연료저정기의 유면이 같아져 압평형이 이루어지면 연료의 흐름은 정지된다.At this time, since the pressure on the fuel tank side is higher than the fuel reservoir 11 side, the rubber member is pushed up and the fuel flows from the fuel tank to the fuel reservoir 11. Afterwards, when the fuel tank and the fuel reservoir have the same oil level, the fuel flow is stopped.

연료의 요동이나 경사로 중행등으로 인하여 연료탱크내의 유면이 연료저정기보다 낮아지게 되는 경우에는 연료저장기(11)내의 연료압력에 의하여 고무부재가 유입부(20)를 막아 연료가 새는 것을 방지하게 된다.When the oil level in the fuel tank becomes lower than the fuel reservoir due to the fluctuation of the fuel or the running of the ramp, the rubber member blocks the inlet 20 by the fuel pressure in the fuel reservoir 11 to prevent the fuel from leaking. do.

이와 같이 작용하는 본 발명은 연료펌프의 아래에 유입부를 형성시켜 연료저장기내로 유입될 수 있도록 하여 펌프가 부담해야될 용량을 줄임으로써 연료펌프의 송출량 자체를 그 만큼 줄일 수 있으며, 이는 연료펌프에 내장된 모터를 좀더 적은 용량의 부품을 사용함으로 가경의 부담을 덜 수 있을 뿐만 아니라 연료펌프의 송출량을 낮춤으로써 연료탱크 내에 있는 연료의 온도를 줄일 수 있고 이로 인해 증발가스 발생량을 감소시키는 효과를 갖는다.The present invention acting as described above forms an inlet portion under the fuel pump so that it can be introduced into the fuel reservoir, thereby reducing the capacity to be burdened by the pump, thereby reducing the output amount of the fuel pump itself. The use of a smaller capacity part of the built-in motor not only reduces the burden on the landscape, but also reduces the temperature of the fuel in the fuel tank by lowering the output of the fuel pump, thereby reducing the amount of evaporated gas generated. .
