본 고안은 엔진 급가속시 흡기 증대 작용을 하는 밸브 장치에 관한 것이다.The present invention relates to a valve device that acts to increase the intake air during rapid acceleration of the engine.

터어보 챠져(TURBO CHARGER)는 같은 크기의 엔진에 장착하므로서 자연 흡인 엔진보다 20%-30%의 출력증대를 얻을수 있기 때문에 점차 그 이용도가 높아지고 있다.The turbocharger is being used more and more because it can be installed in the same size engine and can achieve 20% -30% more power than a natural suction engine.

그러나, 급가속시에는 배기 가스에 의해 구동되는 터어보챠져의 터어빈의 응답성이 느려 흡입공기를 압출시켜 주는 콤프레샤가 거꾸로 저항체가 되어 공기 흡입을 방행하기 때문에 불완전 연소에 의한 매연이 커다란 문제점으로 되어 있다.However, during rapid acceleration, the response of the turbine of the turbocharger driven by the exhaust gas is slow, and the compressor that extrudes the intake air becomes the resistor upside down, so that the intake of air is a big problem. have.

특히 우리나라와 같이 FREE ACCEL SMOKE를 규제하는 경우에 이 급가속시의 매연은 규제치에 걸리게 되므로 본 고안은 이러한 문제점을 해결하기 위하여 고안한 것으로서 이를 첨부 도면에 의거하여 상세히 설명하면 다음과 같다.Particularly in the case of regulating FREE ACCEL SMOKE as in Korea, the smoke during this rapid acceleration takes a regulated value, so the present invention is designed to solve this problem.

엔진본체(1)의 배기매니 포울드(2)와 흡기 매니 포울드(3) 및 흡기관(3') 사이에 설치한 터어보 챠져(6')의 샤프트(4)의 배기 매니 포울드 쪽에는 터어빈(5)를, 흡기 매니 포울드 측에는 콤프레샤(6)를 설치하고, 흡기관(3')과 흡기매니 포울드(3) 사이에 콤프레샤를 거치지 않는 흡입통로(3")를 설치하며, 다이아프램막(9)으로 (가)방과 (나)방을 이루고 코일스프링(10)을 장설한 다이아프램(8)의 로드(11) 선단이 밸브(12)를 착설하여 밸브(12) 밸브(12)를 흡입통로(3")의 밸브시이트(13)에 설치되게하고, 다이아프램(8)의 (가)방을 흡입관(3')에, (나)방을 흡기 매니 포울드(3)에 통기관(7)으로 연통케 함으로서(가) 방과(나) 방사이의 압력 차에 의해 밸브(12)를 개폐 작용케 하였다.On the exhaust manifold side of the shaft 4 of the turbocharger 6 'installed between the exhaust manifold 2 of the engine body 1, the intake manifold 3 and the intake pipe 3'. A turbine (5), a compressor (6) on the intake manifold side, a suction passage (3 ") that does not go through the compressor between the intake pipe (3 ') and the intake manifold (3), The tip of the rod 11 of the diaphragm 8, in which the diaphragm film 9 forms the (a) room and the (b) room, and the coil spring 10 is installed, installs the valve 12 and the valve 12 ( 12) is installed in the valve seat 13 of the suction passage 3 ", (a) of the diaphragm (8) to the suction pipe (3 '), and (b) to the intake manifold (3). By communicating with the vent pipe 7, the valve 12 was opened and closed by the pressure difference between the room and the room.

이와 같이 된 본 고안은 엔진을 급가속하게 되면 터어빈(5)이 배기 가스에 의해 작동 되나 기계 자체의 저항등에 의해 서서히 속도가 증대 된다.When the engine is rapidly accelerated as described above, the turbine 5 is operated by the exhaust gas, but the speed is gradually increased by the resistance of the machine itself.

이때 충분한 속도를 얻기 까지는 콤프레샤(6)가 흡입 공기의 저항체로 작용하기 때문에 흡기관(3')에 비하여 흡기매니 포울드(3) 측의 압력이 작게 된다.At this time, since the compressor 6 acts as a resistor for intake air until a sufficient speed is obtained, the pressure on the intake manifold 3 side is smaller than that of the intake pipe 3 '.

이 경우 다이아 프램(8)에서 흡기관(3')의 압이 걸리는 (가)의 방이 넓어지고, 흡기 매니 포울드(3)와 압이 걸리는 (나)의 방이 작어져 로드(11)는 밸브(12)를 흡기 매니 포울드(3) 안쪽으로 밀어 밸브 시이트(13) 부위가 열리게 되며, 따라서 저항체로 작용하는 콤프레샤(6)에 의하여 흡기 매니 포울드(3)내에 생긴 부압은 밸브(12)가 열림에 따라 해소되고 점차로 터어빈(5)의 속도가 증대하게 되면서 콤프레샤(6)의 속도가 증대되어 충분한 콤프레샤의 역할을 하게 되면 흡기관(3')의 압보다 흡기 매니 포울드(3)의 압이 크게 되어 흡기 매니 포울드(3)와 연결된 (나)방이 커지고 흡기관(3')에 연결된 (가)방이 작아지며 코일스프링(10)의 작용도 가제됨으로서 다이아프램막(9)은 원 위치로 돌아와 밸브(12)가 닫아면서 터어보 챠져에 의한 정상적인 흡입 작용이 이루어지게 된다.In this case, the diaphragm 8 becomes wider in the room where the pressure of the intake pipe 3 'is applied, and the room 11 in which the intake manifold 3 and the pressure is applied becomes smaller, so that the rod 11 is a valve. (12) is pushed into the intake manifold (3) to open the valve seat (13) part, so that the negative pressure generated in the intake manifold (3) by the compressor (6) acting as a resistor is the valve (12) As the opening is eliminated and the speed of the turbine 5 is gradually increased, the speed of the compressor 6 is increased to serve as a sufficient compressor, so that the pressure of the intake manifold 3 is greater than that of the intake pipe 3 '. As the pressure increases, the (na) room connected to the intake manifold 3 becomes larger, the (a) room connected to the intake pipe 3 'becomes smaller, and the action of the coil spring 10 is also attenuated. Return to the position and close the valve 12 so that normal suction action by the turbocharger is achieved. do.
