이하, 본 고안의 바람직한 일 실시예를 첨부한 도면에 의하여 더욱 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings a preferred embodiment of the present invention will be described in more detail.
도1은 본 고안에 따른 인젝터의 누유 방지장치를 도시한 도면이고, 도2는 도 1의 A부를 확대도시한 사시도로, 부호(20)은 인젝터의 누유 방지장치를 지칭한다.1 is a view showing a leak prevention apparatus of the injector according to the present invention, Figure 2 is a perspective view showing an enlarged portion A of Figure 1, reference numeral 20 denotes a leak prevention apparatus of the injector.
상기한 인젝터 누유 방지장치(20)는 인젝터(22)의 스핀들(24)을 탄지하는 탄성부재(26)를 쳄버(28)에 개재하고 있으며, 이 쳄버(28)의 상부에 전원과 연결되어 분사 종료시 전자제어장치(30)의 제어로 전자석(32)이 자화되게 설치하고 있다.The injector leakage preventing device 20 includes an elastic member 26 that holds the spindle 24 of the injector 22 in the chamber 28, and is connected to a power supply to the upper portion of the chamber 28 and sprayed thereon. At the end, the electromagnet 32 is provided to be magnetized by the control of the electronic controller 30.
그리고 상기한 전자석(32)의 저면에 바아(34)로 스핀들(24)에 연결되면서 탄성부재(26)의 내주연에 고정자서(36)을 개재 설치하여 이루어지고 있다.And it is made by installing the stator 36 on the inner circumference of the elastic member 26 while being connected to the spindle 24 by the bar 34 on the bottom of the electromagnet 32.
상기한 바와 같은 본 고안의 작용을 도2에 의하여 설명하면, 연료펌프에 의해 공급포트(38)로 연료가 공급되면 유로(40)를 통해 유압쳄버(42)에 충진이 이루어진다.Referring to Figure 2 illustrates the operation of the present invention as described above, when the fuel is supplied to the supply port 38 by the fuel pump is filled in the hydraulic chamber 42 through the flow path (40).
상기한 유압쳄버(42)에 충진된 유압이 니들밸브(44)의 경사부(46)에 전달되면 니들밸브(44)는 상승하게 되고, 주공급포트(48)를 통해 쳄버(28)에 충진되어 있던 연료는 스핀들(24)에 의해 막혀 있던 개폐공(50)을 통과한 후, 분사공(52)을 통해 분사가 이루어진다.When the hydraulic pressure filled in the hydraulic chamber 42 is transmitted to the inclined portion 46 of the needle valve 44, the needle valve 44 is raised, and is filled in the chamber 28 through the main supply port 48. The used fuel passes through the opening / closing hole 50 blocked by the spindle 24, and then is injected through the injection hole 52.
그리고 나서 상기한 인젝터(22)의 공급포트(38)로 공급되는 유압이 연료펌프에 의해 낮아지면 쳄버(28)내의 탄성부재(26)에 의한 탄압으로 스핀들(24)이 하강하게 되는 분사 종료시점에서 전자제어장치(30)가 전자석(32)에 전원을 인가하게 된다.Then, when the hydraulic pressure supplied to the supply port 38 of the injector 22 is lowered by the fuel pump, the injection end point at which the spindle 24 is lowered by the pressure of the elastic member 26 in the chamber 28 is lowered. In the electronic control device 30 to apply power to the electromagnet (32).
상기한 전자석(32)의 자화로 스핀들(24)에 바아(34)로 연결되어 고정자석(36)은 반발력에 의해 하강하여 스필들(24)에 의해 개폐공(50)을 차단함과 동시에 니들밸브(44)는 분사공(52)을 차단하게 된다.The magnetization of the electromagnet 32 is connected to the spindle 24 by the bar 34, the fixed magnet 36 is lowered by the repulsive force to block the opening and closing hole 50 by the spills 24 and at the same time the needle The valve 44 blocks the injection hole 52.
이때, 차량의 주행중에 진동이나 기관의 구동으로 진동이 스핀들과 니들밸브에 전달되더라도 개폐공과 분사공을 완벽하게 차단하게 되는 고안이다.At this time, even when the vibration is transmitted to the spindle and the needle valve while driving the vehicle or the vibration of the engine is designed to completely block the opening and closing holes and injection holes.
상기한 인젝터의 개폐공과 분사공을 정확하게 막게됨에 따라 분사종료후 연료의 누유가 방지되어 불완전연소를 해소하게된다.As the opening and closing holes of the injector are correctly blocked, leakage of fuel is prevented after the injection is completed, thereby eliminating incomplete combustion.
상기한 연료의 불완전연소를 해소하게 되어 대기오염 배출가스를 줄이게 되는 고안이다.The incomplete combustion of the fuel is devised to reduce the air pollution emission gas.
