Abstract
A flow restrictor element, especially for restricting the air flow in an air duct system of a vehicle, comprises a ring-shaped restrictor element carrier (12) to be arranged on a flow guide duct as well as at least one restrictor element (28). The at least one restrictor element (28) is arranged within the restrictor element carrier (12), radially inwardly in relation to a central axis (M) of the flow restrictor element (10) and is detachable from the restrictor element carrier (12) for changing a restriction cross-sectional area, wherein a locking device (16) is provided on an outer circumferential area (14) of the restrictor element carrier (12) for locking the restrictor element carrier (12) on a flow guide duct.
