Description
본 발명은 퓨얼레일(fuel rail)의 일단측에 설치되는 연료 압력조절기(fuel pressure regulator)에 관한 것으로, 더 상세히는 연료에 포함된 이물질을 필터링하는 기능을 갖도록 한 자동차용 연료 압력조절기에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fuel pressure regulator installed at one end of a fuel rail, and more particularly, to a fuel pressure regulator for an automobile having a function of filtering foreign substances contained in fuel. will be.
도1은 종래의 자동차용 연료 압력조절기의 설치상태 요부 단면도이고, 도4는 일반적인 자동차 연료장치의 구성도이다.1 is a cross-sectional view showing main parts of a conventional fuel pressure regulator for a vehicle, and FIG. 4 is a block diagram of a general automobile fuel device.
도1 및 도4에 도시한 바와같이, 자동차 연료장치의 구성요소중의 하나인 연료 압력조절기(10)는, 1차측(11)이 퓨얼레일(20)에 연결되고 2차측(12)이 연료탱크(40)에 연결되며 외부 파일럿압력측(13)이 흡기 다기관(30)에 연결되어 흡기 다기관(30) 내의 압력변화에 대응하여 연료 분사량을 항상 일정하게 유지시키는 기능을 하는 것으로, 고속시에는 연료 분사량이 많기 때문에 작동하지 않으나 저속시에는 연료소비량이 적으므로 과잉의 연료는 연료탱크(40)로 되돌려 보내 엔진의 회전속도에 관계없이 연료의 압력을 일정하게 유지하도록 한다.1 and 4, the fuel pressure regulator 10, which is one of the components of the automobile fuel system, has a primary side 11 connected to the fuel rail 20 and a secondary side 12 It is connected to the fuel tank 40 and the external pilot pressure side 13 is connected to the intake manifold 30 to keep the fuel injection amount constant in response to the pressure change in the intake manifold 30, There is a large amount of fuel injection does not operate, but at a low speed, since the fuel consumption is small, excess fuel is returned to the fuel tank 40 to maintain a constant pressure of the fuel regardless of the rotation speed of the engine.
미설명부호 70은 연료 인젝터이다.Reference numeral 70 denotes a fuel injector.
이러한 연료 압력조절기(10) 내부에 이물질이 존재하게 되면 오작동되므로 연료펌프(50)의 출구측에 필터(60)를 설치하여 연료에 포함된 이물질을 제거하고 있으나, 필터(60)의 성능이 떨어지거나 제기능을 수행하지 못하여 이물질이 유입되어 오작동되는 경우가 있다.If foreign matters are present in the fuel pressure regulator 10, a malfunction may occur. Thus, a filter 60 is installed at the outlet of the fuel pump 50 to remove foreign matters contained in the fuel. However, the performance of the filter 60 decreases. Otherwise, foreign substances may enter and malfunction due to inability to function.
또한, 퓨얼레일(20)의 가공시에 그 내부에 존재하였던 이물질이 연료 압력조절기(10)에 곧바로 유입되어 오작동되는 경우도 있었다.In addition, foreign matters that existed therein at the time of processing of the fuel rail 20 immediately flowed into the fuel pressure regulator 10 and malfunctioned in some cases.
본 발명은 이러한 종래의 문제점을 해소하기 위한 것으로, 연료에 포함된 이물질이 내부로 유입되기 직전에 필터링할 수 있는 기능을 갖는 자동차용 연료 압력조절기를 제공하는데 있다.The present invention is to solve such a conventional problem, to provide a fuel pressure regulator for a vehicle having a function that can filter the foreign matter contained in the fuel immediately before it is introduced into the interior.

본 발명에 따르면, 1차측(11)이 퓨얼레일(20)에 연결되고 2차측(12)이 연료탱크(40)에 연결되며 외부파일럿압력측(13)이 흡기 다기관(30)에 연결되어 흡기 다기관(30) 내의 압력변화에 대응하여 연료 분사량을 항상 일정하게 유지하는 기능을 하는 자동차용 연료 압력조절기(10)에 있어서,According to the invention, the primary side 11 is connected to the fuel rail 20, the secondary side 12 is connected to the fuel tank 40 and the external pilot pressure side 13 is connected to the intake manifold 30 In the fuel pressure regulator 10 for an automobile, which functions to maintain a constant fuel injection amount in response to a pressure change in the intake manifold 30,
상기 일차측 입구를 확대 형성하여 안착부(11a)를 형성하고, 상기 안착부(11a)에 반구형의 필터엘리먼트(80)를 끼워놓은 것에 그 특징이 있다.The primary side inlet is enlarged to form a seating portion 11a, and the hemispherical filter element 80 is fitted into the seating portion 11a.
이하, 본 발명의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명하며, 종래와 동일한 부분에 대하여는 동일한 부호를 부여하기로 한다.DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, and like reference numerals refer to like parts.
도2는 본 발명에 따른 자동차용 연료 압력조절기의 분해 사시도이고, 도3은 본 발명에 따른 자동차용 연료 압력조절기의 설치상태 요부 단면도이다.Figure 2 is an exploded perspective view of a fuel pressure regulator for a vehicle according to the present invention, Figure 3 is a sectional view of the main portion of the installation state of the fuel pressure regulator for a vehicle according to the present invention.
도2및 도3에 도시한 바와같이, 안착부(11a)는 1차측(11)을 돔형상으로 확대형성하여 필터엘리먼트(80)를 내장시킬 수 있도록 한다.As shown in Figures 2 and 3, the seating portion (11a) is formed to enlarge the primary side (11) in the dome shape so that the filter element 80 can be embedded.
필터엘리먼트(80)는 매우 가는 와이어를 직물조직으로 만든것을 반구형상으로 성형하고 그 테두리를 커버로 마감하는 방법으로 제작한것을 도시한 것으로, 기타 여러가지 재질로도 만들 수 있을 것이다.The filter element 80 shows that a very thin wire made of a fabric structure is formed by forming a hemispherical shape and closing the edge with a cover, and may be made of various other materials.
이와같이 만든 필터엘리먼트(80)를 안착부(11a)에 끼워놓은 상태에서 종래와 마찬가지로,도4에도시한 바와같이, 연료 압력조절기(10)의 1차측(11)은 퓨얼레일(20)에 연결하고 2차측(12)은 연료탱크(40)에 연결하며 외부파일럿압력측(13)은 흡기 다기관(30)에 연결하면된다.As shown in Fig. 4, the primary side 11 of the fuel pressure regulator 10 is connected to the fuel rail 20 in the state in which the filter element 80 thus made is inserted into the seating portion 11a. The secondary side 12 is connected to the fuel tank 40 and the external pilot pressure side 13 is connected to the intake manifold 30.
이와같이 연료가 연료펌프(50)에 의해 펌핑되어 필터(60)를 통과하면서 1차적으로 이물질이 필터(60)링되며, 퓨얼레일(20)에서 과잉의 연료가 연료탱크(40)로 되돌려 지기 위하여 연료 압력조절기(10)로 유입될 때 그 1차측(11)에 있는 필터엘리먼트(80)를 통과하면서 2차적으로 이물질이 필터링된다.In this way, the fuel is pumped by the fuel pump 50 and the foreign matter is primarily filtered through the filter 60, and the excess fuel is returned to the fuel tank 40 in the fuel rail 20. In order to enter the fuel pressure regulator 10, the foreign material is filtered secondly while passing through the filter element 80 on the primary side 11.
이와같이, 연료에 포함된 이물질이 연료 압력조절기(10)로 유입되기 직전에 필터링함으로 이물질로 인한 오작동을 방지할 수 있다.As such, the foreign matter contained in the fuel may be filtered immediately before flowing into the fuel pressure regulator 10 to prevent malfunction due to the foreign matter.
한편, 연료 압력조절기(20)의 1차측(11)을 퓨얼레일(20)로부터 탈거하여 필터엘리먼트(80)의 교체나 세정을 쉽게할 수 있다.On the other hand, the primary side 11 of the fuel pressure regulator 20 can be removed from the fuel rail 20 to facilitate replacement or cleaning of the filter element 80.
상술한 바와같이 본 발명에 따른 자동차용 연료 압력조절기(10)는 1차측(11)에 필터엘리먼트(80)를 내장시켜 연료에 포함된 이물질이 내부로 유입되기 직전에 필터링할 수 있도록 한 것으로, 연료에 포함된 이물질로 인한 오작동을 방지와 엔진의 성능이 저하되는 현상을 방지하는 효과가 있다.As described above, the fuel pressure regulator 10 for a vehicle according to the present invention has a filter element 80 embedded in the primary side 11 so that the foreign matter contained in the fuel can be filtered immediately before the inflow. There is an effect to prevent malfunction due to foreign matter contained in the fuel and to prevent the performance of the engine is degraded.
