Description

인젝션 노즐{Injection nozzle}Injection nozzle

본 발명은 인젝션 펌프에서 보내오는 고압의 연료를 연소실내에 분사하는 인젝션 노즐에 관한 것이다.The present invention relates to an injection nozzle for injecting a high-pressure fuel from the injection pump into the combustion chamber.

인젝션 노즐은 도 4에 도시하는 것과 같이 노즐 홀더(30)의 분사구멍(31)을 개폐하는 니들 밸브(32), 연료입구부(33)로부터 유입되는 연료압에 의해 니들 밸브(32)를 하강시키기 위해 니들 밸브(32)상부에 형성된 콘트롤 체적(34), 연료입구부(33)로부터 연료통로(35)를 통해 니들 밸브(32)의 원추형부(32a)로 유입되어 니들 밸브(32)를 연료압에 의해 상승시키기 위해 형성된 어큐물 레이저 체적 (36), 콘트롤 체적(34)을 확장시켜 콘트롤 체적(34)내로 유입되는 연료압을 낮추거나 또는 높이도록 시트부(37)를 막거나, 상승하여 확장 체적(38)과 연통시키는 솔레노이드 밸브(39)를 포함하여 구성되어 있다.As shown in FIG. 4, the injection nozzle lowers the needle valve 32 by the fuel pressure flowing from the needle valve 32 and the fuel inlet part 33 that open and close the injection hole 31 of the nozzle holder 30. In order to make the needle valve 32 flow into the conical portion 32a of the needle valve 32 through the fuel passage 35 from the control volume 34 and the fuel inlet portion 33 formed on the needle valve 32. The accumulator laser volume 36 and the control volume 34 formed to increase by the fuel pressure are expanded to block or raise the seat portion 37 to lower or increase the fuel pressure flowing into the control volume 34. And a solenoid valve 39 in communication with the expansion volume 38.

도시한 구조의 종래의 인젝션 노즐에 의하면 연료 분사시엔 솔레노이드(40)가 여자되어 솔레노이드 밸브(39)가 상승하여 볼(4)이 시트부(37)로부터 떨어지게 되어 콘트롤 체적(34)이 확장 체적(38)과 연통하여 콘트롤 체적내의 연료압이 강하되며, 이에따라 어큐물 레이터 체적(36)에 작용하는 연료압에 의해 니들 밸브(32)가 상승하므로써 개방된 분사구멍(31)을 통해 연료가 분사된다.According to the conventional injection nozzle of the illustrated structure, when the fuel is injected, the solenoid 40 is excited and the solenoid valve 39 is raised so that the ball 4 is separated from the seat portion 37 so that the control volume 34 is expanded. The fuel pressure in the control volume drops in communication with 38), whereby the fuel is injected through the open injection hole 31 by raising the needle valve 32 by the fuel pressure acting on the accumulator volume 36. .

연료분사시기가 종료되면 솔레노이드(40)에 인가되는 전원 공급이 끊기게 되고, 솔레노이드 밸브(39)는 스프링(42) 탄발력에 의해 하강하여 볼(41)이 시트부(37)에 밀착하므로써 확장체적(38)과의 연통 상태가 해제된 콘트롤 체적(34)내의 연료압이 높아지며, 원추형부(32a)에 작용하는 전압력보다 니들 밸브(32, 니들 밸브 상단 면적이 원추형부보다 큼) 상면에 작용하는 전압력이 크므로 니들 밸브 (32)가 하강하여 분사구멍(31)이 막히게 되므로써 연료분사가 종료되도록 구성되어 있다.When the fuel injection time is finished, the power supply applied to the solenoid 40 is cut off, the solenoid valve 39 is lowered by the spring 42 elastic force, the ball 41 is in close contact with the seat portion 37 by expanding the volume The fuel pressure in the control volume 34, in which the state of communication with the 38 is released, increases, and acts on the upper surface of the needle valve 32 (the needle valve upper area is larger than the conical portion) than the voltage force acting on the conical portion 32a. Since the high pressure force causes the needle valve 32 to descend, the injection hole 31 is blocked, and thus the fuel injection is completed.

그러나 상기와 같은 종래 구조에 의하면 연료압을 콘트롤하기 위한 콘트롤 부위(콘트롤 체적과 확장체적)가 커서 인젝션 노즐의 전체 부피가 증대되고, 또 연료의 통로가 복잡하여 인젝션 노즐의 두께가 두꺼워지게 되어 배기량이 작고 복잡한 구조의 실린더 헤드에는 설치하기가 곤란하다는 문제점이 있다.However, according to the conventional structure as described above, the control portion (control volume and expansion volume) for controlling the fuel pressure is large, and the total volume of the injection nozzle is increased, and the passage of the fuel is complicated, so that the thickness of the injection nozzle becomes thick, and thus the displacement This small and complicated cylinder head has a problem in that it is difficult to install.

이에 본 발명은 상기한 문제점을 감안하여 제안한 것으로서 그의 목적으로 하는 것은 구조가 간단하고 좌,우 대칭을 이루고 있어 가공이 쉬우며, 인젝터의 두께를 얇게 할 수 있어 실린더 헤드의 냉각 통로 확보에 유리한 인젝션 노즐을 제공하는 데 있다.Accordingly, the present invention has been proposed in view of the above-mentioned problems, and its object is to provide a simple structure, symmetrical left and right symmetry, easy to process, and thinner injector, which is advantageous for securing a cooling passage of the cylinder head. To provide a nozzle.
