Abstract (en)

A variable valve lift actuator includes a first body rotating within a preset angle range through rotation of a cam coupled to a camshaft, a second body coupled to or decoupled from the first body to open or close a valve through the rotation of the cam, a latching pin provided retractably forward the first body through the second body to couple or decouple the first body to or from the second body, a driving module to retractably actuate the latching pin, a rotation shaft provided on the valve such that the first body is rotatable, and a return spring to return the first body rotated by the cam to an original position thereof. A deactivation control operation of the valve is to deactivate a cylinder by the latching pin by decoupling the first and second bodies from each other at a low-speed and low-load state of an engine.
