본 발명은 엔진의 연료분사기에 관한 것으로서, 보다 상세하게는 연료분사기 내부에서 발생하는 소음을 차단시키는 차음효과를 충분히 발휘하면서도, 연료분사기의 사출성형시에 사출성형성을 향상시킬 수 있도록 하는 기술에 관한 것이다.The present invention relates to a fuel injector of an engine, and more particularly, to a technology that can sufficiently improve the injection molding during injection molding of a fuel injector while sufficiently exhibiting a sound insulation effect that blocks noise generated inside the fuel injector. It is about.

연료분사기는 통상 내부에 솔레노이드가 자기장을 형성할 수 있도록 되어 있고, 상기 자기장의 형성 여부에 따라 동작하여 공급받은 연료를 분사하도록 하는 니들이 구비되어 있다.The fuel injector is generally provided with a solenoid so as to form a magnetic field therein, and is provided with a needle for injecting the supplied fuel by operating according to the formation of the magnetic field.

상기한 바와 같은 연료분사기에서는 상기 솔레노이드가 니들을 구동함에 따라 니들의 충돌음이 반복적으로 발생하여 외부로 전파되므로, 이러한 소음을 적절히 차단시켜줄 필요가 있다.In the fuel injector as described above, since the impact sound of the needle is repeatedly generated and propagated to the outside as the solenoid drives the needle, it is necessary to appropriately block such noise.

종래에 상기한 바와 같은 연료분사기의 차음효과 향상을 위해 솔레노이드 주위를 감싸는 원통형부재를 인서트한 상태로 연료분사기의 외부를 이루는 하우징이 사출성형되도록 하는 구조가 있다.In order to improve the sound insulation effect of the fuel injector as described above, there is a structure in which the housing forming the outside of the fuel injector is injection molded while inserting a cylindrical member surrounding the solenoid.

그러나 상기한 바와 같은 구조의 연료분사기는 상기 원통형부재에 의해 연료분사기의 차음효과를 개선할 수는 있겠으나, 연료분사기의 구조나 크기 및 형상의 제약상 상기 원통형부재가 솔레노이드의 외측에 매우 밀접한 상태로 삽입되므로, 상기 하우징의 사출성형시에, 상기 원통형부재와 솔레노이드 사이 및 솔레노이드 내측의 공간에 수지가 원활히 유입되기 어려운 문제점이 있다.However, the fuel injector having the structure as described above may improve the sound insulation effect of the fuel injector by the cylindrical member, but the cylindrical member is very close to the outer side of the solenoid due to the structure, size, and shape of the fuel injector. Since it is inserted into, the injection molding of the housing, there is a problem that the resin is difficult to smoothly flow into the space between the cylindrical member and the solenoid and the inside of the solenoid.

즉, 종래의 구조에서 솔레노이드와 원통형부재 사이의 조밀한 공간으로 수지가 충분히 원활하게 삽입되도록 하기 위해서는 사출압을 상승시켜야 하는데, 이는 제조되고 있는 연료분사기의 다른 부분 및 사출기에 무리한 부하를 주게 되어 각종 변형 등과 같은 부작용을 초래하게 되며, 솔레노이드와 원통형부재 사이의 공간에 사출시 쉽게 빠져 나오지 못하는 공기에 의한 공극이 발생하는 등 수지의 충진효율이 크게 저하될 수 있는 구조적 취약점이 있는 것이다.That is, in the conventional structure, the injection pressure must be increased in order to insert the resin into the dense space between the solenoid and the cylindrical member sufficiently smoothly, which imposes an excessive load on the other parts and the injection machine of the fuel injector being manufactured. There is a side effect such as deformation, there is a structural weakness that can significantly reduce the filling efficiency of the resin, such as a void caused by air that does not easily come out during injection into the space between the solenoid and the cylindrical member.

본 발명은 상기한 바와 같은 문제점을 해결하기 위하여 안출된 것으로서, 솔레노이드 주위에 원통형부재를 구비하여 솔레노이드와 니들의 상호 작용에 의한 연료분사기의 소음이 외부로 누출되는 것을 효과적으로 차단할 수 있도록 하면서도, 사출성형에 의해 연료분사기를 제조하는 과정에서 솔레노이드와 원통형부재 사이에 수지가 원활하게 충진될 수 있도록 하여 연료분사기의 사출성형성을 크게 개선할 수 있도록 한 엔진의 연료분사기 구조를 제공함에 그 목적이 있다.The present invention has been made to solve the problems as described above, while having a cylindrical member around the solenoid to effectively block the noise of the fuel injector due to the interaction of the solenoid and the needle to the outside, injection molding It is an object of the present invention to provide a fuel injector structure of an engine that enables the resin to be smoothly filled between the solenoid and the cylindrical member in the process of manufacturing the fuel injector to greatly improve the injection molding of the fuel injector.
