Gas flow and sound control valve for exhaust gas system

A gas flow and sound control valve for an exhaust system of an internal combustion engine, the gas flow and sound control valve comprising:

• a Y-shaped housing including an inlet, a first outlet, and a second outlet, and a valve member arranged within the Y-shaped housing for forming a first conduit connecting the inlet to the first outlet and a second conduit from the inlet to the second outlet, wherein the valve member is configured to be moved relative to the Y-shaped housing between a first predetermined position in which the valve member closes the second conduit and a second predetermined position in which the valve member closes the first conduit,
• wherein the valve member comprises a spoon-shaped section for guiding exhaust gas from the inlet through the first conduit and/or the second conduit,
• wherein the spoon-shaped section defines an inner surface which, in the first predetermined position or the second predetermined position, merges with an inner conduit surface of a respective open conduit to define a boundary for an exhaust gas flow path resembling that of a bent pipe,
• wherein the valve member is rotatable around a valve axis aligned parallel to a centerline of the inlet,
• wherein the valve member is rotatably mounted to the Y-shaped housing with a central bearing arranged in the Y-shaped housing between the first outlet and the second outlet,
• wherein the valve member includes a shaft section aligned coaxially with the valve axis and extending through the central bearing and through the Y-shaped housing,
• wherein the valve member includes a wedge-shaped transition section arranged between the spoon-shaped section and the shaft section, and
• wherein the wedge-shaped transition section extends, in the first or second predetermined position, radially from an upstream tip of the spoon-shaped section into the respective open conduit and having a transition surface shaped corresponding to that of the respective open conduit and connecting the inner conduit surface of the respective open conduit to the inside surface.
