摘要： The invention relates to a valve unit for at least one of influencing and controlling a gas flow in an internal combustion engine comprising at least one valve member for modifying a cross-section of a gas flow-carrying channel through which a fluid flows and a drive train for rotatingly driving the at least one valve member. The drive train comprises an input shaft, which is drivingly coupled to a drive device in the mounted state, and at least one valve member shaft which is non-rotationally connected to the valve member. It is especially advantageous if the drive train comprises at least one phase adjuster for drivingly coupling the input shaft and the valve member shaft, a rotational position of the shafts in relation to each other being adjustable by the phase adjuster.

摘要： An exhaust gas recirculation apparatus (5) for an internal combustion engine (1), in particular in a motor vehicle, has an exhaust gas recirculation line (9) which can be connected at the inlet end to an exhaust gas system (4) of the internal combustion engine (1) and at the outlet end to a fresh gas system (3) of the internal combustion engine (1) and having a return valve (12) arranged in the exhaust gas recirculation line (9) for adjusting an exhaust gas recirculation rate by varying the flow-through cross section of the exhaust gas recirculation line (9). To improve the efficacy of the exhaust gas recirculation, the exhaust gas recirculation valve (12) is designed so that it adjusts the respective exhaust gas recirculation rate at least in one operating state of the exhaust gas recirculation apparatus (5), so that it alternately reduces and increases and/or blocks and opens the flow-through cross section of the exhaust gas recirculation line (9) at predetermined or regulated switching points in time.
