Description
본 고안은 소음저감형 차량용 인젝터에 관한 것으로서, 보다 상세하게는 인젝터의 니들밸브 일측에 댐퍼를 형성하여 주므로써 상기 인젝터가 고압의 분사압력으로 연료를 연소실로 공급할 시 인젝터의 니들밸브 일단이 하우징의 분사구 일측에 큰 힘으로 접촉됨을 방지하여 소음을 저감시키고, 내구성을 향상시킬 수 있는 소음저감형 차량용 인젝터에 관한 것이다.The present invention relates to a noise reduction vehicle injector, and more particularly, by forming a damper on one side of the needle valve of the injector, when the injector supplies fuel to the combustion chamber at a high pressure injection pressure, one end of the needle valve of the injector is The present invention relates to a noise reduction vehicle injector capable of reducing noise by improving contact with one side of a jet hole and improving durability.
잘 아는 바와 같이, 내연기관은 연소실로 흡입되는 연료와 공기의 혼합기를 연소시켜 이에 발생되는 폭발력으로 피스톤을 상하 직선 왕복 운동시키고, 이의 직선 왕복운동을 크랭크 기구로서 회전운동으로 변환시켜 회전동력을 얻는 것으로서, 그 대표적인 예로 자동차 엔진을 들 수 있다.As is well known, the internal combustion engine burns a mixture of fuel and air sucked into the combustion chamber, and causes the piston to linearly reciprocate up and down with the explosive force generated therefrom, and converts its linear reciprocation into rotational movement as a crank mechanism to obtain rotational power. As a representative example thereof, an automobile engine may be mentioned.
최근에 이와 같은 내연기관의 연료공급장치는 종전의 기화기방식에서 탈피하여 기관의 부하와 회전속도에 따라 최적의 연료와 공기의 혼합기량을 제어하고, 각 실린더간에 균일한 혼합기를 조성할 수 있도록 하는 ECU(Electronic Control Unit)제어방식 연료분사장치 즉, 통상적으로 칭하는 전자제어방식 연료분사장치가 보편화되고 있다.In recent years, such a fuel supply device of an internal combustion engine is to avoid the conventional carburetor method to control the optimum amount of fuel and air mixture according to the load and rotational speed of the engine, and to create a uniform mixer between each cylinder BACKGROUND ECU (Electronic Control Unit) control type fuel injection devices, that is, commonly referred to as electronic control type fuel injection devices are becoming common.
이와 같은 전자제어분사방식에서는 연료를 분사밸브 즉, 인젝터를 통하여 흡입행정초기에 흡기밸브 전방에 분사하게 되어 공기와 함께 연소실내로 유입되게 된다.In such an electronically controlled injection method, fuel is injected in front of the intake valve at the beginning of the intake stroke through an injection valve, that is, an injector, and is introduced into the combustion chamber together with air.
이러한 종래의 차량용 인젝터를 첨부도면을 참조하여 설명하면 다음과 같다.Referring to the accompanying drawings, such a conventional vehicle injector is as follows.
첨부된 도면 도 1은 종래의 차량에 구비된 인젝터를 도시한 단면도로서, 엔진의 실린더헤드(미도시) 일측에 구비되는 인젝터(2)는 그 하우징(4) 내부의 일단에 연료의 인입시 이물질을 제거하는 필터(6)가 구비되고, 상기 하우징(4)의 중앙부에는 스프링(8)이 구비되며, 이 스프링(8)의 양측에는 솔레노이드(10)가 구비되고, 상기 솔레노이드(10)에 의해 전,후로 이동되는 플런저(12)가 스프링(8)의 일단에 구비되며, 상기 플런저(12)의 일단에 일체로 형성되어 플런저(12)와 동일하게 작동하는 니들밸브(14)가 구비되고, 상기 니들밸브(14)의 일단에 형성되어 상기 하우징(4)의 일끝단에 형성된 분사구(18)에 삽입되므로 이 분사구(18)를 개폐가능하게 하는 스핀들(16)로 이루어졌다.1 is a cross-sectional view illustrating an injector provided in a conventional vehicle, wherein an injector 2 provided at one side of a cylinder head (not shown) of an engine has a foreign substance when fuel is introduced into one end of the housing 4. Filter 6 is provided to remove the, the central portion of the housing 4 is provided with a spring 8, both sides of the spring 8 is provided with a solenoid 10, by the solenoid 10 A plunger 12 moved forward and backward is provided at one end of the spring 8, and a needle valve 14 is formed integrally with one end of the plunger 12 to operate in the same way as the plunger 12. The spindle 16 is formed at one end of the needle valve 14 and inserted into the injection hole 18 formed at one end of the housing 4 to open and close the injection hole 18.
이와 같이 이루어진 차량용 인젝터는 이 인젝터(2)의 내부에 구비된 솔레노이드(10)에 차량에 구비된 ECU(미도시)로 부터 소정의 신호가 인가되면 상기 솔레노이드(10)에 의해 플런저(12)가 스프링(8)을 압축시키면서 흡인된다. 그러면 상기 플런저(12)에 일체로 형성된 니들밸브(14)가 흡인되면서 이 니들밸브(14)의 일단에 일체로 형성된 스핀들(16)을 흡입하고, 이 스핀들(16)의 흡인으로 인해 상기 인젝터(2)의 분사구(18)가 열리게 되므로 인젝터(2)에 유입된 연료가 연소실로 분사되게 된다.In the vehicle injector, the plunger 12 is driven by the solenoid 10 when a predetermined signal is applied to the solenoid 10 provided in the injector 2 from an ECU (not shown) provided in the vehicle. The spring 8 is sucked while compressing. Then, the needle valve 14 formed integrally with the plunger 12 is sucked in and sucks the spindle 16 integrally formed at one end of the needle valve 14, and the suction of the spindle 16 causes the injector ( Since the injection hole 18 of 2) is opened, the fuel introduced into the injector 2 is injected into the combustion chamber.
그리고, 이때 연소실로 분사되는 연료분사량은 니들밸브(14)가 흡입되어 스핀들(16)이 열려 있는 시간, 즉 상기 솔레노이드(10)에 ECU로 부터 인가된 전류가 통전되는 시간에 의해 결정되며, 이 통전시간은 상기 ECU가 각 센서들로부터 입력된 정보를 종합,처리하여 결정된다.In this case, the fuel injection amount injected into the combustion chamber is determined by the time when the needle valve 14 is sucked in and the spindle 16 is opened, that is, the time when the current applied from the ECU to the solenoid 10 is energized. The energization time is determined by integrating and processing information input from each sensor by the ECU.
상기 솔레노이드(10)에 전류가 흐르지 않게 되면, 상기 플런저(12)에 의해 흡인된 니들밸브(14)는 압축된 스프링(8)이 그 탄발력으로 상기 플런저(12)를 밀어 내게 되므로 플런저(12)에 일체로 형성된 니들밸브(14)가 분사구(18)측으로 이동되고, 이 니들밸브(14)의 이동으로 인해 스핀들(16)이 인젝터(2)의 분사구(18)에 삽입되므로 상기 분사구(18)를 폐쇄시켜 연료의 분사를 방지하게 된다.When no current flows in the solenoid 10, the needle valve 14 sucked by the plunger 12 causes the compressed spring 8 to push the plunger 12 with its repulsive force so that the plunger 12 The needle valve 14 formed integrally with () is moved to the injection hole 18 side, and the spindle 16 is inserted into the injection hole 18 of the injector 2 due to the movement of the needle valve (14). ) To prevent fuel injection.
그러나, 이와 같이 이루어진 종래의 차량용 인젝터는 차량의 외부로 배출되는 배기가스를 저감시키기 위한 방편으로 연소실에 연료를 분사할 시 인젝터는 연소실에 고압으로 연료를 분사하게 된다. 이때, 연료분사 후 인젝터내의 솔레노이드에 전류가 흐르지 않게 되어 니들밸브가 원위치로 복귀되면서 스핀들이 인젝터의 분사구로 삽입될 시, 상기 인젝터의 높은 분사압으로 인해 상기 니들밸브의 일단이 분사구의 일측에 큰 힘으로 접촉되므로 소음이 발생되며, 내구성이 저하되는 문제점이 있었다.However, in the conventional vehicle injector, the injector injects fuel at high pressure into the combustion chamber when the fuel is injected into the combustion chamber as a means for reducing the exhaust gas discharged to the outside of the vehicle. At this time, when the injection of the needle valve is returned to its original position and the spindle is inserted into the injection hole of the injector after fuel injection, one end of the needle valve is large at one side of the injection hole due to the high injection pressure of the injector. Since the noise is generated by contact with the force, there was a problem that the durability is reduced.
본 고안은 상기와 같은 종래의 문제점을 해결하기 위한 것으로, 인젝터가 고압의 분사압력으로 연소실내에 연료를 분사하고, 분사구가 폐쇄될 시 상기 인젝터의 니들밸브 일단이 분사구의 일측에 큰 힘으로 접촉됨을 방지하여 소음을 저감시키고, 내구성을 향상시키기 위한 소음저감형 차량용 인젝터를 제공하는데 그 목적이 있다.The present invention is to solve the conventional problems as described above, the injector injects fuel in the combustion chamber at a high pressure injection pressure, when the injection port is closed, one end of the needle valve of the injector with a large force to one side of the injection port The purpose of the present invention is to provide a noise reduction vehicle injector for preventing noise and improving durability.
상술한 목적을 달성하기 위한 본 고안의 기술적 구성은 차량용 인젝터에 있어서, 상기 인젝터의 니들밸브 일측에 돌출형성되어 그 일측이 절곡된 암부를 형성하고, 상기 암부의 일끝단에 충격을 흡수하는 댐퍼를 구비하며, 상기 암부의 댐퍼가 삽입되어 상하로 이동가능하도록 하우징 일측에 삽입홈을 형성하되, 상기 삽입홈에 삽입된 암부의 댐퍼는 상기 니들밸브의 행정과 동일하게 형성되어 이 니들밸브의 일단이 인젝터의 분사구 일측에 접촉되는 시점과 동시에 상기 암부의 댐퍼가 삽입홈의 하단에 접촉되도록 구성한 것을 특징으로 한다.The technical configuration of the present invention for achieving the above object is a vehicle injector, protruding to one side of the needle valve of the injector to form a bent portion of one side of the injector, a damper for absorbing the shock at one end of the arm portion And an insertion groove is formed at one side of the housing so that the damper of the arm is inserted and movable up and down, and the damper of the arm inserted into the insertion groove is formed in the same manner as the stroke of the needle valve so that one end of the needle valve is injector. Simultaneously with the point of contact with one side of the injection port of the arm is characterized in that the damper is configured to be in contact with the bottom of the insertion groove.

이하 본 고안의 바람직한 실시예를 첨부도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, described in detail with reference to the accompanying drawings a preferred embodiment of the present invention.
첨부된 도면 도 2는 본 고안에 따른 소음저감형 인젝터를 도시한 단면도이다.2 is a cross-sectional view showing a noise reduction injector according to the present invention.
도시된 바와 같이, 차량용 인젝터(2)에 있어서, 상기 인젝터(2)의 니들밸브(14) 일측에 절곡형성된 암부(30)를 일체로 형성한다.As shown, in the vehicle injector 2, the arm portion 30 is formed integrally bent to one side of the needle valve 14 of the injector (2).
상기 암부(30)의 일끝단에는 충격 또는 진동을 흡수하고, 음의 진폭을 경감시키는 댐퍼(32)를 구비한다.One end of the arm portion 30 is provided with a damper 32 for absorbing shock or vibration and reducing the amplitude of sound.
상기 암부(30)의 댐퍼(32)가 삽입되어 상하로 이동가능하도록 하우징(4) 일측에 소정길이의 삽입홈(40)을 형성한다.The damper 32 of the arm 30 is inserted to form an insertion groove 40 of a predetermined length on one side of the housing 4 so as to be movable up and down.
이때, 상기 인젝터(2)의 하우징(4)에 형성된 삽입홈(40)에 삽입된 암부(30)의 댐퍼(32)의 행정은 니들밸브(14)가 인젝터(2)내에서 상하 이동되는 행정과 동일하게 형성된다. 즉, 상기 니들밸브(14)의 스핀들(16)이 인젝터(2)의 분사구(18)에 삽입될 시 니들밸브(14)의 일단이 분사구(18)의 일측에 접촉되는 시점과 동시에 상기 암부(30)의 댐퍼(32)가 삽입홈(40)의 하단에 접촉되어 충격을 흡수하도록 구성된다.At this time, the stroke of the damper 32 of the arm portion 30 inserted into the insertion groove 40 formed in the housing 4 of the injector 2 and the stroke of the needle valve 14 is moved up and down within the injector 2. Is formed identically. That is, when the spindle 16 of the needle valve 14 is inserted into the injection hole 18 of the injector 2, the arm portion (at the same time as the point of contact of one end of the needle valve 14 with one side of the injection hole 18) The damper 32 of 30 is in contact with the lower end of the insertion groove 40 is configured to absorb the shock.
상기와 같이 구성된 본 고안에 따른 소음저감용 인젝터는 인젝터(2) 내부의 솔레노이드(10)에 전류가 인가되면 상기 솔레노이드(10)에 의해 플런저(12)가 스프링(8)을 압축시키면서 흡인된다. 그러면 상기 플런저(12)에 일체로 형성된 니들밸브(14)가 흡인되면서 이 니들밸브(14)의 일단에 일체로 형성된 스핀들(16)과 일측에 형성된 암부(30)를 흡인하게 되고, 상기 암부(30)의 일끝단에 구비된 댐퍼(32)는 하우징(4)의 삽입홈(40)내에서 상방향으로 이동하게 된다. 상기 인젝터(2)는 스핀들(16)의 흡인으로 인해 인젝터(2)의 분사구(18)가 열리게 되므로 인젝터(2)에 유입된 연료가 고압의 분사압력으로 연소실로 분사되게 된다.When the current is applied to the solenoid 10 inside the injector 2, the plunger 12 is sucked by the solenoid 10 while the plunger 12 compresses the spring 8. Then, the needle valve 14 integrally formed on the plunger 12 is sucked and sucks the spindle 16 integrally formed at one end of the needle valve 14 and the arm part 30 formed at one side thereof. The damper 32 provided at one end of the 30 is moved upward in the insertion groove 40 of the housing 4. Since the injector 2 opens the injection hole 18 of the injector 2 due to the suction of the spindle 16, the fuel introduced into the injector 2 is injected into the combustion chamber at a high pressure injection pressure.
그리고, 상기 솔레노이드(10)에 전류가 흐르지 않게 되면, 상기 플런저(12)에 의해 흡인된 니들밸브(14)는 압축된 스프링(8)이 그 탄발력으로 상기 플런저(12)를 밀어 내게 되고, 이 플런저(12)에 일체로 형성된 니들밸브(14)는 플런저(12)에 의해 분사구(18)측으로 이동되어 니들밸브(14)의 일단에 형성된 스핀들(16)이 분사구(18)에 삽입되게 되는데, 이때 상기 암부(30)의 댐퍼(32)가 니들밸브(14)의 행정과 동일하므로 상기 니들밸브(14)의 일단이 분사구(18)의 일측에 접촉될 시 이 니들밸브(14)에 일체로 형성된 암부(30)의 댐퍼(32)가 하우징(4)의 삽입홈(40) 하단에 동시에 접촉되면서 충격 및 소음을 흡수하여 니들밸브(14)와 분사구(18)의 접촉으로 인한 소음을 저감시키게 된다.When no current flows through the solenoid 10, the needle valve 14 sucked by the plunger 12 pushes the plunger 12 with the spring force of the compressed spring 8. The needle valve 14 formed integrally with the plunger 12 is moved to the injection hole 18 by the plunger 12 so that the spindle 16 formed at one end of the needle valve 14 is inserted into the injection hole 18. At this time, since the damper 32 of the arm part 30 is the same as the stroke of the needle valve 14, when one end of the needle valve 14 is in contact with one side of the injection port 18, the needle valve 14 is integrally formed. The damper 32 of the formed arm portion 30 simultaneously contacts the lower end of the insertion groove 40 of the housing 4 to absorb shock and noise to reduce noise caused by the contact between the needle valve 14 and the injection hole 18. do.
이상에서 살펴 본 바와 같이, 본 고안의 소음저감형 차량용 인젝터는 인젝터의 하우징 일측에 니들밸브와 연동되는 댐퍼를 삽입형성하여 니들밸브의 일단이 분사구의 일측에 접촉될 시 상기 댐퍼가 하우징의 삽입홈 하단에 접촉되어 충격 및 소음을 흡수하게 되므로써 인젝터의 작동시 소음을 저감시키고, 내구성을 향상시킬 수 있는 효과가 있다.As described above, the noise reduction vehicle injector of the present invention inserts a damper interlocked with a needle valve on one side of the injector housing so that the damper is inserted into the housing when one end of the needle valve is in contact with one side of the injection hole. By contacting the lower end to absorb shock and noise, there is an effect that can reduce the noise during operation of the injector, and improve the durability.
