| 摘要 |
The invention relates to a device (20) for adjusting a rate of flow of air flowing along an air duct, comprising: a tubular body (22) extending along an axis (24); at least one flap (28) able to pivot about an axis transverse to the axis (24) of the body (22); a ring (34) mounted to pivot on an end portion (22b) of the body (22) about the axis (24) of this body; each flap (28) being provided with a male drive means and the ring (34) being provided with a female drive means, or vice versa, the male drive means and the female drive means being arranged in such a way that, in response to the ring (34) being pivoted about the body (22), the male drive means engages with the female drive means to alter the position of each flap (28) and hence the cross section available for the passage of air. |

1. A device for adjusting a flow rate of air flowing in an air duct, comprising:
a tubular body extending along an axis fluidly connected to the air duct; at least one flap extending inside the body and adapted to pivot about an axis transverse to the axis of the body, to occupy a plurality of positions corresponding to a plurality of air passage cross sections; a ring pivotally mounted on an end portion of the body about the axis of this body; each flap being provided with a male drive means, and the ring being provided with a female drive means, or vice versa, the male drive means and the female drive means being arranged in such a way that, in response to a pivoting of the ring on the body, the male drive means cooperates with the female drive means to alter the position of each flap and, as a consequence, the air passage cross section. |
