Abstract

A continuously variable valve lift apparatus may include a camshaft, a cam portion on which a cam is formed and into which the camshaft is inserted, a slider housing into which the cam portion is rotatably inserted and a position thereof is rotatable around a pivot shaft, a control portion configured to selectively push the slider housing to be rotated, a spring guide connected to the slider housing for elastically supporting the slider housing, a rotation deliverer configured to transmit rotation of the camshaft to the cam portion, an output portion rotatable around the pivot shaft and onto which a valve shoe is formed, and a valve unit configured to be driven by the valve shoe.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2015-0133342 filed on Sep. 21, 2015, the entire contents of which are incorporated herein for all purposes by such reference. technical field [0003] The invention relates to a continuously variable valve lift device and an engine provided with the device. More particularly, the present invention relates to a continuously variable valve lift device capable of changing the valve lift according to the operating conditions of the engine with a simple configuration and an engine provided with the same . Background technique [0004] An internal combustion engine generates power by burning fuel in a combustion chamber in a medium of air drawn into the combustion chamber. The intake valve is operated by the camshaft to draw in air, which is drawn into the combustion chamber while the intake valve is open. In addition, the exhaust valves are operated b...
