    • 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).

    • PURPOSE: A continuously variable valve lift apparatus is provided to use in a V-type engine by making valve profiles of the continuously variable valve lift apparatuses, which are symmetrical, identical. CONSTITUTION: A continuously variable valve lift apparatus comprises an input cam(110), a follower supporting part(200), a follower(300), a linear guide(400), an output cam(500), and a valve opening/closing part(600). The input cam is installed on a cam shaft(100). The follower is supported by the follower supporting part. The location of the central axis of the follower is varied along the circumferential direction of the cam shaft. The follower reciprocates around the central axis by being delivered with the rotation of the input cam. The output cam is contacted with the follower and reciprocates along the linear guide. The valve opening/closing part is opened and closed by being contacted with the output cam. The follower supporting part is formed in the cam shaft to be rotated.
