본 고안은 자동차용 연료 분사장치에 관한 것으로서 연료분사 노즐을 개폐하는 솔레노이드 장치의 구동봉을 가늘게 형성하며 중간부에 날개편을 형성하여 그 무게를 줄임으로써 솔레노이드 코일의 부피를 줄이고 솔레노이드에 고장이 발생하였을 경우에는 연료분사장치를 통채로 교체하지 않고 솔레노이드 코일만은 따로 교체할 수 있도록 하여 기기보수와 교체에 따르는 비용을 절감할 수 있도록 한 연료 분사장치에 관한 것이다.The present invention relates to a fuel injector for automobiles. The drive rod of the solenoid device that opens and closes the fuel injection nozzle is thinly formed, and the blade pieces are formed in the middle to reduce the weight of the solenoid coil and cause the solenoid to break down. In this case, it is related to a fuel injector that enables the solenoid coil to be replaced separately without replacing the entire fuel injection device, thereby reducing the cost of equipment repair and replacement.
종래의 자동차용 연료분사장치는 분사노즐을 솔레노이드 장치로 개폐토록 되어 있으나 이러한 솔레노이드장치는 분사노즐을 개폐하는 구동봉이 -자형으로 솔레노이드 코일 사이에 위치되는 것으로서 그 구조상 크기가 커지므로 무겁게 되고 이에 따라 구동봉을 작동시키기 위한 전자력을 크게하기 위하여서는 솔레노이드코일의 권선부의 부피가 커지게 되어 전체적인 부피 상승의 원인과 제조원가의 상승요인이 되었을 뿐 아니라 솔레노이드 장치가 분해 조립의 불가능한 상태로 되었기 때문에 연료 분사장치의 고장중 가장 높은 빈도수를 갖는 솔레노이드 코일의 파손(단락이나 단선)시에도 전체를 새것으로 교체하여야 되기 때문에 매우 불합리하고 보수비용이 많이 들게 되는 문제점이 있었다.The conventional fuel injection device for automobiles is to open and close the injection nozzle with the solenoid device, but such a solenoid device is a driving rod for opening and closing the injection nozzle, which is located between the solenoid coils in the shape of a magnet and becomes heavy because of its structure. In order to increase the electromagnetic force for operating the enclosed rod, the volume of the winding part of the solenoid coil is increased, which not only causes an increase in the overall volume and an increase factor in manufacturing cost, but also the solenoid device becomes impossible to disassemble and assemble. Even when the solenoid coil having the highest frequency of failure (short or disconnection) has to be replaced with a new one, there is a problem that it is very unreasonable and expensive to repair.
본 고안은 이와같은 문제점을 해결하기 위한 것으로 자동차용 연료 분사장치의 솔레노이드크기를 감소시켜서 기기의 소형 경량화는 물론 제조원가를 절감토록 하고 솔레노이드 코일의 파손시 장치 전체를 교체치 않고 솔레노이드 코일만 새것으로 교체할 수 있도록 하여 기기 보수작업에 따르는 비용을 절감하고 보수작업에 편리를 도모할 수 있도록 한 자동차용 연료 분사장치를 제공함을 본 고안의 목적으로 하는 것으로서 이하 첨부된 도면을 참조하여 본 고안의 구성 및 작용효과를 상세히 설명하면 다음과 같다.The present invention has been made to solve the above problems, reducing the size of the solenoid of the fuel injector for automobiles to reduce the size and weight of the device as well as to reduce the manufacturing cost. It is an object of the present invention to provide a fuel injector for automobiles that can reduce the cost of equipment maintenance work and to facilitate the maintenance work. Detailed description of the effect is as follows.
우선 본 고안의 구서은 제1(a)도, 제1(b)도에 도시된 바와 같이 하우징(1)내에 솔레노이드본체(2)를 끼워넣고 그 일단면 외곽에 패킹(3)을 사이에 두고 덮개용테(4)를 나사(5)로 하우징(1)에 조여서 고정토록 하되 솔레노이드본체(2)에 수장된 솔레노이드코일(6)사이에는 얇은 날개편(7')을 가진 구동봉(7)을 구동봉지지대(8)속에 끼워 스프링(9)으로 탄지함과 동시에 구동봉(7)의 일단은 구동 범위 조정용나사(10)단부에 맞닿도록 하고 그 타단은 노즐구멍(11)을 개폐하는 볼(12)을 부착하여서 된 것이다.First of all, according to the present invention, the solenoid body 2 is inserted into the housing 1 as shown in FIGS. Tighten the fuselage (4) to the housing (1) with screws (5) to fix it, but drive the drive rod (7) having a thin blade (7 ') between the solenoid coils (6) stored in the solenoid body (2). The ball 12 which is inserted into the rod support 8 and is supported by the spring 9 and at the same time the one end of the driving rod 7 abuts the end of the driving range adjusting screw 10 and the other end of the ball 12 opens and closes the nozzle hole 11. ) Is attached.
미설명부호 8'는 가이드부, 11'는 노즐의 경사면, 13, 14, 15, 16은 고무링, 17은 연료유입구멍, 18은 연료공급관, 19는 솔레노이드 코일 고정링이다.Reference numeral 8 'is a guide portion, 11' is a slope of the nozzle, 13, 14, 15, 16 is a rubber ring, 17 is a fuel inlet hole, 18 is a fuel supply pipe, 19 is a solenoid coil fixing ring.
이와같이 구성된 본 고안의 작용효과는 제1(a)도에 도시된 바와 같이 전원이 공급되지 않는 상태에서는 자장이 발생하지 않으므로 스프링(9)의 탄성력에 의해 구동봉(7)이 노즐구멍(11)쪽으로 밀려서 볼(12)이 경사면(11')에 밀착되므로 노즐구멍은 막혀 있게된다.As shown in FIG. 1 (a), since the magnetic field does not occur in the state in which the power is not supplied, the driving rod 7 is driven by the elastic force of the spring 9 so that the driving rod 7 has the nozzle hole 11. As the ball 12 is pushed toward the inclined surface 11 ', the nozzle hole is blocked.
이 상태에서 솔레노이드코일(6)은 전원이 공급되면 자장이 발생하여 구동봉(7)이 제1(b)와 같이 솔레노이드코일(6)에 달라붙게 되어 볼(12)이 경사면(11')에서 이탈되어 노즐구멍(11)이 열리게 되어 연료가 연료공급관(18)으로 부터 연료유입구멍(17)을 통해 노즐구멍(11)으로 분사되어지는 것이다.In this state, when the power is supplied, the solenoid coil 6 generates a magnetic field so that the driving rod 7 sticks to the solenoid coil 6 like the first (b) so that the ball 12 is inclined at the inclined surface 11 '. The nozzle hole 11 is opened and the fuel is injected from the fuel supply pipe 18 to the nozzle hole 11 through the fuel inlet hole 17.
이때 스프링(9)은 압축되어지는 것으로 솔레노이드코일에 다시 전원이 차단되면 솔레노이드코일(6)은 자장을 잃게 되고 스프링의 탄성으로 구동봉(7)이 제1(a)도와 같이 원위치되어 볼(12)이 노즐구멍(11)을 막게된다.At this time, when the spring 9 is compressed and the solenoid coil is cut off again, the solenoid coil 6 loses its magnetic field and the driving rod 7 is returned to its original position as shown in FIG. ) Closes the nozzle hole 11.
즉 솔레노이드코일(6)에 전원이 인가 및 차단됨에 따라 볼(12)이 노즐구멍(11)을 개폐하게 되는 것이다.That is, the ball 12 opens and closes the nozzle hole 11 as power is applied to the solenoid coil 6 and cut off.
그런데 이때 구동봉(7)은 그 중심축 부위가 가늘고 이에 수직 방향으로 날개편(7')이 형성되어 솔레노이드코일(6)과 접속되는 면적이 넓으므로 작은 솔레노이드의 힘으로도 작동이 가능하게 되어 솔레노이드코일(6)의 크기를 작게할 수 있는 것이다.However, at this time, the driving rod 7 has a thin central axis portion and a wing piece 7 'is formed in the vertical direction so that the driving rod 7 has a large area connected to the solenoid coil 6, thereby enabling operation even with a small solenoid force. The size of the solenoid coil 6 can be made small.
또한 구동봉(7)의 일단은 작동시에 나사(10)의 단부에 걸리게 되기 때문에 나사를 조이거나 푸는 거리에 따라 구동봉(7)의 작동범위를 손쉽게 조절할 수 있는 것이다.In addition, one end of the driving rod 7 is caught by the end of the screw 10 during operation, so that the operating range of the driving rod 7 can be easily adjusted according to the distance of tightening or loosening the screw.
그리고 분사장치의 고장시 특히 솔레노이드코일(6)의 파손시에는 종래에는 분사장치 전체를 교체해야 되지만 본 고안에서는 나사(5)를 풀어서 덮개용테(4)와 패킹(3)을 분해한 다음 솔레노이드 노즐본체(2)를 하우징(1)에서 빼내면 구동봉지지대(8)와 구동봉(7) 및 솔레노이드코일(6)이 분해되기 때문에 솔레노이드 코일만을 새것으로 교체하여 상기와 역순으로 재조립하면 간단히 보수 및 수리가 되는 것이다.In case of failure of the injector, in particular, when the solenoid coil 6 is damaged, the entire injector must be replaced in the prior art. However, in this design, the screw 5 is disassembled to disassemble the cover frame 4 and the packing 3, and then the solenoid nozzle When the main body 2 is pulled out of the housing 1, the driving rod support 8, the driving rod 7 and the solenoid coil 6 are disassembled. Therefore, simply replace the solenoid coil with a new one and reassemble it in the reverse order. And repairs.
이와같이 본 고안에 의하면 자동차용 연료 분사장치의 솔레노이드의 크기를 줄일 수 있어 기기의 소형 경량화는 물론 제조원가의 절감을 도모할 수 있고 분사장치의 고장시에는 고장난 부위만을 간단히 교체할 수 있어 보수비용의 절감이 가능해 지게 되는 것이다.Thus, according to the present invention, the size of the solenoid of the fuel injector for automobiles can be reduced, so that the device can be reduced in size and weight, and manufacturing cost can be reduced. This will be possible.
