Abstract
The exhaust gas recirculation valve comprises a tubular valve housing includes a gas inlet, a first gas outlet and a second gas outlet located proximate thereto. Located inside the tubular valve housing is a rotatably supported valve body that is designed as a hollow body having a semi-cylindrical lateral surface having a lateral penetration opening. The gas inlet as seen from the top includes a blocking wall on the side thereof facing the first gas outlet and the second gas outlet, the blocking wall being located inside the valve housing perpendicular thereto and having a height equal to at least the length of the valve body and sitting flush against the gas passage in the closed position of the exhaust gas recirculation valve.

An exhaust gas recirculation valve for a motor vehicle, comprising:
- a tubular valve housing, comprising:
- a gas inlet,
- a first gas outlet, and
- a second gas outlet,
- each of the gas inlet, the first gas outlet, and the second gas outlet extending from a lateral outer surface of the tubular valve housing in proximity to one another;
- a rotatably supported valve body arranged within the tubular valve housing configured as a hollow body comprising:
- a semi-cylindrical lateral surface;
- a lateral penetration opening arranged on the semi-cylindrical lateral surface;
- a longitudinal axis of the cylinder that defines the semi-cylindrical lateral surface forming an axis of rotation of the valve body;
- and
- a partition wall arranged on a radius of the semi-cylindrical valve body between the axis of rotation and the semi-cylindrical lateral surface;
- and
- a gas passage arranged on a radius of the semi-cylindrical valve body between the axis of rotation and the semi-cylindrical lateral surface directly opposite the area without a penetration opening;
- and
- a blocking wall of the gas inlet which, in plan view is arranged on a side facing the first gas outlet and the second gas outlet, extending perpendicularly from a lateral inner surface of the tubular valve housing, having a height corresponding to at least the length of the valve body and configured to rest flush against the gas passage in the closed position of the exhaust gas recirculation valve.
