A venturi valve having a valve housing that includes a narrowing section extending between a broader upstream end and a narrower valve throat followed by a broadening section downstream of the valve throat, and a valve member configured to be situated in the valve housing and movable along a valve axis in an axial direction of the valve housing. The venturi valve includes a plurality of flow influencing features positioned in a reattachment region of the valve member and/or extending inward from an inner wall of the valve housing. The plurality of flow influencing features are configured to reduce perturbations in an air flow passing through the venturi valve thereby reducing rattle from the venturi valve.
