Claim:
1. A low-pressure exhaust gas recirculation (EGR) valve comprising: a fresh air inlet; an exhaust gas inlet; an outlet, which is connected to a compressor; and at least one throttling device comprising a first throttle flap and a second throttle flap for influencing a fresh air quantity flowing in through the fresh air inlet and an exhaust gas quantity flowing in through the exhaust gas inlet; wherein a connecting surface situated between the outlet and the exhaust gas inlet is shaped in such a way that condensate flows from the outlet to the exhaust gas inlet, wherein the low-pressure EGR valve is coupled to a low-pressure EGR passage flowing exhaust gas formed by an engine, and wherein the second throttle flap of the throttling device is designed to close the exhaust gas inlet in a closure position, and in which the first throttle flap of the throttling device is a shield which is designed to at least partially shield a surrounding area arranged around the exhaust gas inlet from a gas flow from the fresh air inlet to the outlet in the closure position, and wherein an abscissa passing through the outlet and the fresh air inlet and an ordinate intersecting the abscissa and passing through the exhaust gas inlet form a coordinate system, and in which, in relation to the coordinate system, the connecting surface has a curve profile which falls monotonically from the outlet to the exhaust gas inlet.
