Description
본고안은 디젤엔진용 연료분사 장치에 있어서 니들밸브의 아마츄어를 제어하는 솔레노이드에 관한 것으로, 특히 솔레노이드의 단면을 원형으로 이루어지게 하여 그 흡인력을 증가 되게한 것이다.This paper relates to a solenoid for controlling the armature of a needle valve in a fuel injection device for a diesel engine, and in particular, to make a circular cross section of the solenoid to increase the suction force.
디젤엔진용 유니트 인젝터는 도1의 도시와 같이The unit injector for the diesel engine is as shown in FIG.
몸체(10)의 상부에 플런저(20)를 스프링(30)으로 탄설하여 캠(40)에 의해 작동되는 로커아암(50)에 의해 상하작동되게하고, 그 일측의 아마츄어실(60)에는 솔레노이드(70)를 설치하여 아마츄어(80)를 상하운동케하여 그 밸브(90)를 제어하므로서 연료가 펌프 측에서 솔레노이드 밸브를 거쳐 노즐측으로 연결되는 유로를 연속개폐 되게 구성되어 있다.The plunger 20 is mounted on the upper portion of the body 10 with a spring 30 so as to be operated up and down by the rocker arm 50 operated by the cam 40, and the solenoid ( 70) is installed so that the armature 80 is moved up and down to control the valve 90 so as to continuously open and close the flow path where the fuel is connected to the nozzle side through the solenoid valve on the pump side.
여기에서 상용으로 쓰이는 솔레노이드는 도2의 도시와 같이 "E" 형 철심(100)을 중첩부착 하며 코어(200)를 형성하고 그 중앙에 코일(300)을 감아 단면이 4각형상으로 구성된 것을 사용한다.Solenoids used in the commercial use, as shown in Figure 2, overlapping the "E" type iron core 100, forming a core 200, and wound the coil 300 in the center of the cross-section consisting of a quadrangular shape is used do.
또, 디젤엔진의 유니트 인젝터에 장착되는 솔레노이드는 고압(약 1500bar)을 제어하면서 고속으로 작동 하여야 한다. 그러므로 솔레노이드와 아마츄어(Armature)의 행정거리가 짧고 자속을 최대한 흡수 하기 위해 단면적이 넓은 평면형 아마츄어가 많이 사용되고 있으며, 단면의 면적이 커짐에 따라 자력의 흡인력 역시 커짐을 다음의 식에 의해서도 알 수 있다.In addition, the solenoid mounted on the unit injector of the diesel engine should be operated at high speed while controlling the high pressure (about 1500 bar). Therefore, the planar armature with large cross-sectional area is used to absorb the magnetic flux as much as possible, and the suction force of the magnetic force also increases as the area of the cross section increases.
Fm = 자기력 ( Magnetic Force )Fm = Magnetic Force
B = 자속밀도 ( Magnetic Incluction )B = Magnetic Incluction
S = 단면적 ( Poleface area)S = Poleface area
μ°= 투자율 (Permea bility)μ ° = Permea bility
그러나 전기한 기존의 솔레노이드는 단면이 4각형으로 되어 있기 때문에 점유공간에 비해 면적효율이 적으므로 전기한 식에서와 같이 단면적(S)의 감소로 흡인력 역시 비례적으로 줄어들므로서 면적효율이 떨어지는 문제가 있다.However, because the former solenoid has a square cross section, the area efficiency is smaller than that of the occupied space. Therefore, the suction force is also proportionally reduced due to the reduction of the cross-sectional area (S) as in the above equation. have.
본고안은 전기한 바와같은 문제점을 제거코저 솔레노이드의 단면을 원형으로 이루어지게 하여 동일한 공간에서도 면적효율을 증가시켜 이에 의해 흡인력이 증대된 솔레노이드를 제공함에 그 고안의 목적이 있다.The purpose of the present invention is to provide a solenoid with increased suction force by increasing the area efficiency in the same space by making the cross section of the nose solenoid circular, eliminating the problems described above.

전기한 목적을 이루기 위한 기술 수단으로는, 철심을 좌우중첩하여 코어를 형성하되 그 좌우철심의 형태를 각기 다르게하여 중첩부착시 원형의 코어가 이루어 지게한다.As a technical means for achieving the above object, to form a core by overlapping the iron core left and right, the shape of the left and right iron cores are different so that a circular core is made when overlapping.
이하, 본고안의 실시예를 첨부도면에 의하여 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도3은 본고안의 일부를 절개표시한 사시도이다.3 is a perspective view showing a portion of the present invention cut away.
철심(2)(2')을 좌우로 중첩부착하여 코어(3)를 형성하되, 좌우철심(2)(2')을 서로 형태 및 길이가 다르게하여 부착후 코어(3)가 전체적으로 원형을 이루게하고 중앙에 요함부(4)가 형성되게하여 이에 코일(5)을 감는다.Cores 2 are formed by overlapping and attaching iron cores 2 and 2 'to the left and right sides, but the cores 3 form an overall shape after attachment by attaching the left and right iron cores 2 and 2' to different shapes and lengths. And the concave portion (4) is formed in the center to wind the coil (5).
그 단면과 일정간격으로 이격 설치된 니들밸브(6)의 아마츄어(7)역시 원형으로 형성한다.The armature 7 of the needle valve 6 which is spaced apart at a predetermined interval from the cross section is also formed in a circular shape.
도4는 전기한 철심의 형태를 보다 명확히 표현한 분리사시도이다.Figure 4 is an exploded perspective view more clearly expressing the shape of the iron core described above.
좌우철심(2)(2')의 형태 및 길이는 중첩부착후 형태를 감안하여 형태는 "I"형에서 점차 "ㄷ"형, "ㅌ"형으로 변화되게하고 길이는 점차 원형을 이루는 길이로 변화되게 하여, 좌우부착후 원형을 이루게 한다.The shape and length of the left and right iron cores (2) (2 ') are changed from the "I" type to the "c" type and "하여" shape in consideration of the shape after the overlapping attachment, and the length is gradually formed into a circular length. Change to form a circle after left and right attachment.
이와같은 본고안의 작용을 설명한다.Explain the operation of this paper.
본고안의 의한 솔레노이드를 유니트 인젝터 몸체(10)의 상부 일측에 형성된 아마츄어실(60)에 설치하게 되면 전자적 제어에 의해 아마츄어(7)를 상하운동케 하여 그 밸브(90)를 제어하여 연료가 펌프 측에서 솔레노이드 밸브를 거쳐 노즐 측으로 연결되는 유로를 연속개폐 되게 한다.When the solenoid of the present invention is installed in the armature chamber 60 formed on the upper side of the unit injector body 10, the armature 7 is moved up and down by electronic control to control the valve 90 so that the fuel is pumped. In order to open and close the flow path connected to the nozzle side through the solenoid valve at.
이때 본고안의 솔레노이드 단면이 원형을 이루고 있으므로 도5의 도시와 같이 이에 내접되는 쇄선으로 표시한 종래의 4각 솔레노이드에 비하여 면적이 넓어지게 된다.At this time, since the cross section of the solenoid of the present invention has a circular shape, the area becomes wider than that of the conventional quadrilateral solenoid indicated by the chain line inscribed therein as shown in FIG.
그러므로 흡인력
이상과 같이 본고안은 디젤엔진용 연료분사장치에 있어서, 솔레노이드의 단면을 원형으로 이루어 지게 하므로서 면적효율이 증가되어 그 흡인력이 상승하므로서 유니트 인젝터의 고압연료를 제어하면서 고속으로 작동케 하여 유니트 인젝터의 효 율을 높힐 수 있는 효과가 있다.As described above, the present invention has a circular cross section of a solenoid in a diesel engine fuel injection device, and the area efficiency is increased and the suction power is increased, so that the high pressure fuel of the unit injector is operated to operate at a high speed to control the unit injector. It is effective to increase the efficiency.
