Patent ID: 7753015

Claim:
A device for regulating a lift characteristic of an exhaust charge cycle valve of an internal combustion engine, comprising: a controllable electric motor having an actuator element for actuating the exhaust charge cycle valve; a regulating device for controlling the electric motor; and two energy storage units acting in opposite drive directions on the exhaust charge cycle valve, wherein the regulating device controls the electric motor according to at least one stored setpoint path, the at least one setpoint path defining actuation of the actuator element such that the exhaust charge cycle valve is transferred between a first end position and a second end position by swiveling a rotor of the electric motor, and the at least one stored setpoint path includes at least two different setpoint paths provided for regulating the speed of the rotor of the electric motor, whereby a lower kinetic energy is transferred to the exhaust charge cycle valve under one of the at least two different setpoint paths during a valve opening process than under another of the at least two different setpoint paths.
