Zusammenfassung: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.
