Abstract
A control device for an internal combustion engine. The control device is arranged in a bypass duct between a pressure side and an intake side of a supercharging device. The control device includes a bypass valve comprising a valve-closure body which is configured to be pneumatically actuatable, and a control pressure space. A solenoid valve is configured so that a fluidic connection can be established and closed via the control pressure space between either the pressure side and the intake side or between the pressure side and the atmosphere: When the bypass valve is in a completely open position, the fluidic connection exists at least temporarily via the control pressure space between either the pressure side and the intake side or between the pressure side and the atmosphere. A closure of the fluidic connection brings about a resulting force in a closing direction on the valve-closure body.
