Abstract: 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).

Abstract: A variable valve lift device operating two valves simultaneously in an engine of a vehicle is provided to reduce a pressure loss by directly introducing a hydraulic pressure to a high speed locker arm, with the hydraulic pressure not passing through a low speed locker arm. A variable valve lift device operating two valves simultaneously in an engine of a vehicle includes first and second low speed locker arms, a high speed locker arm(30), a connecting arm, a latching pin(50), and a hydraulic line(P). The first and second low speed locker arms are apart from a shaft(10) of the locker arm and are rotated along with a low speed cam. Valves are mounted to the first and second low speed locker arms respectively. The high speed locker arm is disposed between the first and the second low speed locker arm and is rotated with respect to the shaft of the locker arm by a high speed cam. The connecting arm is engaged with the first and second low speed locker arms to integrally connect the first and second low speed locker arms. The latching pin is accommodated in a pin moving section(34) formed in the high speed locker arm and is resiliently moved by the hydraulic pressure supplied to the pin moving section to be integrally engaged with the connecting arm. The hydraulic line is formed in the shaft of the locker arm and the high speed locker arm to supply the hydraulic pressure to the pin moving section.

A variable valve lift apparatus of an engine for a vehicle includes a high speed arm(10), a low speed arm(20), a compression pin(30), a center pin(31), and a return spring(32). The high speed arm has a rocker arm. A body formed of vertical plates and a bottom plate is rotatably installed at a rocker arm shaft. The low speed arm is disposed between the both vertical plates of the high speed arm to be rotatably mounted on the rocker arm shaft. The compression pin is installed in one side of a circular cylinder connected to an oil passage of the high speed arm. The center pin is installed in a roller shaft of the low speed arm.
