An exhaust gas recirculation, EGR, apparatus for a turbocharged internal combustion engine, the EGR apparatus comprising: an air intake duct with a throttle valve configured to control an intake air quantity flowing through the air intake duct to a turbocharger compressor; an exhaust gas recirculation inlet connected to the air intake duct downstream of the throttle valve; and an EGR valve configured to control an exhaust gas quantity recirculated to the turbocharger compressor via the exhaust gas recirculation inlet, wherein: the throttle valve and the EGR valve are combined in a single valve unit in which the valves (14, 16) are separated by a plate configured to substantially prevent exhaust gas from entering the air intake duct in a vicinity of the throttle valve, the valve unit has a main valve body defining a passage through which exhaust gas flows to the exhaust gas recirculation inlet when a movable valve element of the EGR valve is in an open position, and the plate is disposed between the passage of the valve body and the throttle valve; and the movable valve element of the EGR valve is mechanically connected to a movable valve element of the throttle valve by a valve stem which passes through a slot in the plate, wherein the movable valve element of the EGR valve is a valve head movable between a closed position where the valve head is seated on and seals a valve seat, and the open position where the valve head is lifted away from the valve seat of the EGR valve, the valve seat being an aperture positioned in a path of exhaust gas flow between an inlet port and an outlet port of the valve main body of the single valve unit. an air intake duct with a throttle valve configured to control an intake air quantity flowing through the air intake duct to a turbocharger compressor; an exhaust gas recirculation inlet connected to the air intake duct downstream of the throttle valve; and an EGR valve configured to control an exhaust gas quantity recirculated to the turbocharger compressor via the exhaust gas recirculation inlet, wherein: the throttle valve and the EGR valve are combined in a single valve unit in which the valves (14, 16) are separated by a plate configured to substantially prevent exhaust gas from entering the air intake duct in a vicinity of the throttle valve, the valve unit has a main valve body defining a passage through which exhaust gas flows to the exhaust gas recirculation inlet when a movable valve element of the EGR valve is in an open position, and the plate is disposed between the passage of the valve body and the throttle valve; and the movable valve element of the EGR valve is mechanically connected to a movable valve element of the throttle valve by a valve stem which passes through a slot in the plate, wherein the movable valve element of the EGR valve is a valve head movable between a closed position where the valve head is seated on and seals a valve seat, and the open position where the valve head is lifted away from the valve seat of the EGR valve, the valve seat being an aperture positioned in a path of exhaust gas flow between an inlet port and an outlet port of the valve main body of the single valve unit. the throttle valve and the EGR valve are combined in a single valve unit in which the valves (14, 16) are separated by a plate configured to substantially prevent exhaust gas from entering the air intake duct in a vicinity of the throttle valve, the valve unit has a main valve body defining a passage through which exhaust gas flows to the exhaust gas recirculation inlet when a movable valve element of the EGR valve is in an open position, and the plate is disposed between the passage of the valve body and the throttle valve; and the movable valve element of the EGR valve is mechanically connected to a movable valve element of the throttle valve by a valve stem which passes through a slot in the plate, wherein the movable valve element of the EGR valve is a valve head movable between a closed position where the valve head is seated on and seals a valve seat, and the open position where the valve head is lifted away from the valve seat of the EGR valve, the valve seat being an aperture positioned in a path of exhaust gas flow between an inlet port and an outlet port of the valve main body of the single valve unit.
