<p>A valve flap sub-assembly (10), especially of a vehicle's air conditioning unit, has a first valve flap (12) arranged in a rotation-resistant manner on a first shaft, a second valve flap (14) and a free-wheeling device (16) which connects the first shaft to the second valve flap (14). The first valve flap (12) can be rotated by a free-wheeling angle in relation to the second valve flap (14) from an initial position in an adjustment direction and the free-wheeling device (16) drives the second valve flap (14) in the case of rotational angles of the first valve flap (12) being larger than the free-wheeling angle.</p> |
