Abstract

A integrated variable valve actuator assembly of a variable valve lift apparatus may include a rocker arm rotating on a rocker shaft and including an oil supply line with selectively provided oil, a fastener penetrating the side of the rocker arm and discharging oil supplied from the oil supply line through the oil passage, a valve bridge located at the bottom of the fastener and pressurizing valves, an actuator device including an actuator piston being inserted in the valve bridge and formed with an oil supply passage, and an actuator spring being inserted in the actuator piston and providing the actuator piston with elastic force, and a variable control device located at the bottom of the actuator piston and adjusting the heights of the actuator piston by a movement generated by the hydraulic pressure of oil supplied from the oil supply passage.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]The present application claims priority of Korean Patent Application Number 10-2010-0119803 filed in the Korean Intellectual Property Office on Nov. 29, 2010, the entire contents of which application is incorporated herein for all purposes by this reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a integrated variable valve actuator assembly. More particularly, the present invention relates to a variable valve actuator assembly integrated with a valve bridge that comprises a variable control device and an actuator device at the lower end of the valve bridge and changes the height of the actuator device by selective supply of oil.[0004]2. Description of Related Art[0005]An internal combustion engine generates power by burning fuel in a combustion chamber in an air media that is drawn into the chamber. Intake valves are operated by a camshaft in order to intake in the air, and the air ...
