Abstract: Provided is a variable valve lift actuator of an engine, which includes: a first body rotating; a second body; a driving module; and a return spring, wherein an entire portion or a partial front end of the driving module is inserted into a rear end of the second body, the lift degree of the valve is variably controlled in two stages of a high-speed mode and a low-speed mode based on an operating condition of the engine, and when only the high-speed cam is installed on the camshaft, the driving pin is operated in a low-speed and low-load state of the engine to separate the first body from the second body so as to deactivate a cylinder.

Abstract: A variable valve lift actuator of an engine includes a first body that rotates within a predetermined angular range; a second body connected to or disconnected from the first body; a latching pin configured to project to or retract from the first body by passing through the second body to connect or disconnect the first body and the second body; a drive module connected to the latching pin through a connecting member to project or retract the latching pin; a rotary shaft disposed above the valve across both side walls of the first body and the second body such that the first body is rotatable; and a return spring installed on the rotary shaft to provide a restoring force to return the first body rotated by the high-speed cam to an original position thereof.
