CONTINUOUS VARIABLE VALVE LIFT APPARATUS

摘要

PURPOSE: A continuous variable valve lift apparatus is provided to reduce pumping loss of a cylinder by advancing the maximum lift point as the valve lift decreases. CONSTITUTION: A continuous variable valve lift apparatus comprises a control shaft(105), an eccentric member, a roller type follower(155), and a variable arm. The control shaft is arranged in a line with a cam shaft(100) formed with a cam on one side. The eccentric member has an insertion hole in which the control shaft is inserted and an eccentric circumference having a center eccentric from the center of the inner circumference of the insertion hole. The roller type follower is installed on an end of a follower arm extended from a follower loop and contacts with the cam. The variable arm is extended from a variable loop(150) which is installed to slide on the eccentric outer circumference and moves toward or opposite to the center of the control shaft according to the rotation of the control shaft, thereby changing the amount or timing of pressing a swing arm(125).
