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.

Abstract: A variable valve lift apparatus of an engine for a vehicle is provided to independently control each valve to readily obtain an oil passage, thereby increasing latching reliability. 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. The return spring is installed in the other side of the circular cylinder of the high speed arm.
