Abstract: The invention relates to an internal combustion engine system (1), particularly in a motor vehicle, comprising an internal combustion engine (2), a fresh gas system (3) for supplying fresh gas to the internal combustion engine (2), an exhaust gas system (4) for discharging exhaust gas from the internal combustion engine (2), and an exhaust gas recirculation system (5) for removing exhaust gas from the exhaust gas system (4) at a removal point (11) and introducing the removed exhaust gas into the fresh gas system (3) at an introduction point (12). In order to improve exhaust gas recirculation, the exhaust gas system (4) is equipped with an exhaust gas valve (14) downstream of the removal point (11) in order to control the penetrable cross-section of the exhaust gas system (4).

Abstract: The present invention relates to an actuation device (5) for shifting an actuation member (4) between two end positions, in particular for controlling a gas flow in an internal combustion engine, with an armature (13) which is mounted in a stator (14) such that it can move between two end positions in a pivoting manner about a pivot axis (7) and which is connected or can be connected in a rotationally fixed manner to the actuation member (4), with at least one electromagnet (10), which is arranged on or in the stator (14), for generating electromagnetic attractive forces, with at least one first stator-side bearing face (18), against which a first contact face (20) of the armature (13) bears when the armature (13) is in the first end position, and with at least one second stator-side bearing face (19), against which a second contact face (21) of the armature (13) bears when the armature (13) is in the second end position.

Abstract: The present invention relates to a valve device (13) for controlling a gas flow in a fresh air system (6) of an internal combustion engine (2), in particular of a motor vehicle, with a housing (17) which encloses at least one duct section (19) through which the gas flow (14) can pass transversely to the main flow direction (18), with at least one flap (15) which can be rotated about an axis of rotation (21) which runs transversely with respect to the main flow direction (18) in the duct section (19). In order to improve the fail-safety of the valve device (13), at least one rotary frame (24) is provided, which can be rotated about an axis of rotation (25) which runs transversely with respect to the main flow direction (18) in the duct section (19) and has a frame opening (26) through which the gas flow (14) can pass.
