Field of the Invention The present invention relates to an active control valve, and more particularly, to an active control valve capable of preventing a decrease in engine output of a vehicle by minimizing hysteresis occurring in an intake apparatus of a vehicle.

통상 자동차의 흡기장치는 흡입되는 공기 속에 들어있는 먼지 등의 이물질을 제거하는 공기 청정기와, 각 실린더에 혼합기 또는 흡입되는 공기를 분배하는 흡기 매니폴드로 이루어져 있다.In general, the intake apparatus of a vehicle is composed of an air purifier for removing foreign substances such as dust contained in the air to be sucked, and an intake manifold for distributing a mixer or sucked air to each cylinder.

이와 같은 흡기장치는 흡기 행정시, 공기가 에어 덕트와, 에어 크리너, 스로틀 바디 및 서지탱크를 통해 흡기 매니폴드에서 균등 분배되어 각각의 실린더와 연통 설치된 흡기 다기관을 통해 실린더에 유입되도록 되어 있는바, 스로틀 바디의 전개와 동시에 흡기다기관의 진공도가 연소실로 유입 순간 부압이 발생하게 되어 엔진으로 유입되는 공기의 양이 과급되어 이력현상이 발생하였다. 이러한 이력현상은 엔진의 출력을 저하시키는 것은 물론, 디젤 차량의 경우 느린 출발을 야기하는 문제점이 있었다.In the intake apparatus as described above, air is evenly distributed in the intake manifold through the air duct, the air cleaner, the throttle body, and the surge tank so that the air flows into the cylinder through the intake manifold installed in communication with each cylinder. At the same time as the throttle body was developed, the vacuum of the intake manifold generated a negative pressure at the moment of inflow into the combustion chamber, and the hysteresis occurred because the amount of air flowing into the engine was supercharged. This hysteresis not only lowers the output of the engine but also causes a slow start in the case of diesel vehicles.

상기와 같은 문제점을 해결하기 위한 본 발명의 목적은 차량의 흡기장치에서 발생하는 이력현상(Hysteresis)을 최소화할 수 있는 차량용 흡기장치의 능동제어밸브를 제공하는 데 있다.An object of the present invention for solving the above problems is to provide an active control valve of the intake apparatus for a vehicle that can minimize the hysteresis generated in the intake apparatus of the vehicle.

By the negative pressure generated when the vacuum degree of the intake manifold flows into the combustion chamber at the same time as the throttle body is developed during the engine acceleration, one side of the coupling pipe is opened to introduce external air into the body. It provides an active control valve installed in the intake apparatus.
