Air flap for vehicle heating or air conditioning system - has sealing lip acting on rectangular cross-section of air duct.

摘要

The sealing lip (9) is directed against the prevailing flow direction over its total extension length. In consequence the effective flow pressure impinges on the sealing lip in the sense of a reinforcement of the pressing force of the sealing lip, at least at the sealing surface (6). The duct (1) containing the air flap (2) has a rectangular cross-section and each sealing surface is formed as a cylinder cover section whose cylinder axis runs parallel to the swivel axis (3) of the air flap. USE/ADVANTAGE - Air flap for vehicle heating or air conditioning system ensures that full sealing action is maintained under all flow conditions.
