VARIABLE VALE LIFT DEVICE OF ENGINE

To provide a valve device capable of carrying out a pause control operation of a valve for deactivating a variable valve lift device and a cylinder.SOLUTION: A variable valve lift device of an engine, includes: a first body which rotates by rotations of a high-speed cam; a second body which rotates by rotations of the high-speed cam when coupled with the first body, and adjusts the lift amount of a valve by rotations of a low-speed cam when separated from the first body; a drive module makes a drive pin appear and disappear so as to couple or separate the first body and the second body; a rotary shaft provided across both side walls of the first body and the second body; and a return spring which provides restoration force for returning the first body to an original position. The drive module variably controls the lift amount of the valve in two stages of a high-speed mode and a low-speed mode, on the basis of an operation condition of an engine, and when only the high-speed cam is installed on a cam shaft, separates the first body and the second body to deactivate a cylinder, in a low-speed and low load state of the engine.SELECTED DRAWING: Figure 3 【課題】可変バルブリフト装置とシリンダを非活性化させるバルブの休止制御動作を行うことができるバルブ装置を提供する。【解決手段】高速カムの回動により、回動する第１のボディと、第１のボディと連結されると、高速カムの回動によって回動し、第１のボディと分離されると、低速カムの回動によって、バルブのリフト量を調節する第２のボディと、第１のボディと第２のボディを連結又は分離するように、駆動ピンを出没動作させる駆動モジュールと、第１のボディと第２のボディの両側壁を横切って設けられる回転軸と、第１のボディを、本来の位置に戻す復元力を供する戻しバネとを含み、駆動モジュールは、エンジンの運転条件に基づき、バルブのリフト量を高速モードと低速モードの２段に可変制御し、カムシャフトに高速カムだけが設置された場合、エンジンの低速、低負荷状態で、前記第１のボディと第２のボディを分離してシリンダを非活性化させる。【選択図】図３
