More Information
Summary:The present invention relates to an intake manifold capable of stably rotating a variable valve means and securing airtightness with a cylinder head. The intake manifold comprises: a flange shell connected to a surge tank and forming a path for supplying intake air to a cylinder of an engine; a variable valve means disposed inside the flange shell and varying the flow direction of the intake air so as to generate a tumble flow in the intake air flowing into the cylinder; a cage inserted into the flange shell to form an intake passage communicating with an intake port of the cylinder head and to support the variable valve means in rotation; and a sealing unit which is engaged with the flange shell and the cage and is in close contact with the cylinder head to seal the intake passage. 본 발명은 가변밸브수단을 안정적으로 회전되게 지지하고 실린더헤드와의 기밀성을 확보할 수 있는 흡기매니폴드에 관한 것으로서, 상기 흡기매니폴드는 서지탱크와 연결되어 흡기를 공급받아 엔진의 실린더에 공급하는 경로를 형성하는 플랜지쉘과, 상기 플랜지쉘의 내부에 배치되고 상기 실린더에 유입되는 흡기에 텀블 유동이 발생하도록 흡기의 유동 방향을 가변시키는 가변밸브수단과, 상기 플랜지쉘에 삽입되어 상기 실린더헤드의 흡기포트와 연통하는 흡기유로를 형성하고 상기 가변밸브수단을 회전되게 지지하는 케이지, 그리고 상기 플랜지쉘과 상기 케이지에 연계하여 체결되고 상기 실린더헤드에 밀착되어 흡기유로를 실링하는 실링부를 포함한다.
