터보차저의 웨이스트 게이트 밸브 장치 {WASTEGATE VALVE APPARATUS OF TURBOCHARGER FOR VEHICLE}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a wastegate valve device for a turbocharger,

본 발명은 차량의 터보차저에 관한 것으로, 특히 터빈하우징에 설치된 웨이스트 게이트 밸브의 스핀들을 통하여 염수가 하우징의 내부로 침투되어 스핀들이 부식되어 고착되는 것을 방지할 수 있도록 형성된 터보차저의 웨이스트 게이트 밸브 장치에 관한 것이다.
The present invention relates to a turbocharger of a vehicle, and more particularly to a wastegate valve device of a turbocharger, which is formed to prevent salt water from penetrating into a housing through a spindle of a wastegate valve installed in a turbine housing, .

터보차저(turbo charger)는 배기가스의 배출력을 이용하여 터빈을 회전시켜서 이 터빈과 동 축상에 설치된 컴프레서를 작동시킴으로써 외기를 강제로 가압하여 엔진의 연소실로 공급하는 장치로서, 엔진 출력의 향상을 위해 장착된다.
A turbocharger is a device that rotates a turbine by using the exhaust power of exhaust gas and operates the compressor installed on the coaxial shaft with this turbine to forcibly pressurize the outside air and supply it to the combustion chamber of the engine. Respectively.

도 1은 종래의 터보차저 및 웨이스트 게이트를 도시한 도면으로써, 터보차저의 터빈측 부분 즉, 터빈 하우징(10)이 도시되어 있다. 도시된 바와 같이, 측부에 배기가스 입구(11)가 형성되어, 이 입구(11)를 통해 유입된 배기가스가 터빈을 회전시키고 중앙의 출구(12)를 통해 배출되는 구조로 이루어져 있다.
FIG. 1 is a view showing a conventional turbocharger and a waste gate, in which the turbine side portion of the turbocharger, that is, the turbine housing 10, is shown. As shown, an exhaust gas inlet 11 is formed in the side portion, and the exhaust gas flowing through the inlet 11 rotates the turbine and is discharged through the central outlet 12.

한편, 터보차저에는 웨이스트 게이트 밸브(20;waste gate valve)가 설치되는데, 도시된 바와 같이 터빈하우징(10)에서 터빈의 이전 부분에 설치되어 입구(11)로 유입된 배기가스를 터빈을 거치지 않고 바이패스 통로를 통해 출구(12) 이후 부분으로 흐르게 함으로써 터빈의 출력을 제어하여 과급압을 조절하는 기능을 수행한다.
Meanwhile, a waste gate valve 20 is installed in the turbocharger. As shown in the figure, a waste gas valve 20 is installed in a previous portion of the turbine in the turbine housing 10 so that the exhaust gas flowing into the inlet 11 is not passed through the turbine And then flows to the portion after the outlet 12 through the bypass passage to control the output of the turbine to control the boost pressure.

상기 웨이스트 게이트 밸브(20)는 소정 형상의 스핀들(21)에 연결되어 있으며, 이 스핀들(21)이 터빈하우징(10)을 관통하고, 그 단부에 힌지바(22)가 직각으로 연결되며, 이 힌지바(22)의 단부에 회동가능하게 작동로드(23)가 연결된 구조로 설치된다.
The wastegate valve 20 is connected to a spindle 21 of a predetermined shape and the spindle 21 penetrates the turbine housing 10 and the hinge bar 22 is connected at a right angle to its end, And an operating rod 23 is rotatably connected to an end of the hinge bar 22. [

따라서, 액츄에이터 작동에 의해 작동로드(23)가 전후진하여 힌지바(22)가 스핀들(21)을 회동시킴으로써 웨이스트 게이트 밸브(20)가 개폐되도록 되어 있다.
Therefore, the operation rod 23 is moved forward and backward by the actuator operation, and the hinged bar 22 rotates the spindle 21, thereby opening and closing the wastegate valve 20.

또한, 상기 웨이스트 게이트 밸브(20)의 스핀들(21)과 터빈하우징(10)에 형성된 통공의 사이에는 스핀들(21)과 터빈하우징(10)의 직접 마찰을 피하고 보다 부드럽게 작동되도록 하기 위하여 부시(24;bush)가 압입되어 있다.
Between the spindle 21 of the wastegate valve 20 and the through hole formed in the turbine housing 10 there is provided a bush 24 for avoiding direct friction between the spindle 21 and the turbine housing 10, bush) is press-fitted.

그러나, 차량이 바닷가를 주행하거나 겨울철 제설작업을 위한 염화칼슘이 살포된 도로를 운행한 경우에는 염수가 차량의 내부로 비산되어 유입되게 된다. 따라서, 엔진이 작동하여 터빈하우징(10)의 내부에 배기가스 압이 걸릴 때 바로 상기 스핀들(21)과 부시(24) 사이의 미세한 틈을 통하여 염수가 유입되어 부식이 발생함으로써, 밸브가 고착되는 경우가 발생했다.
However, when the vehicle is traveling on the road running on the beach or spraying calcium chloride for winter snow removal, salt water is scattered into the interior of the vehicle. Therefore, when the engine is operated and the exhaust gas pressure is applied to the inside of the turbine housing 10, salt water flows into the fine gap between the spindle 21 and the bush 24 to cause corrosion, There was a case.
