Abstract
The invention concerns a ventilator for a motor vehicle passenger compartment, intended to deliver an air flow towards a space to be conditioned, which comprises: an opening through which an air flow flows during operation, a flared guiding surface (S), extending from the opening, a needle valve () comprising a needle valve head () with: a tip () situated at the end of the needle valve (), a maximum width portion corresponding in shape to the opening (O), with dimensions of between 80% and 100% of those of the opening (O), a base () flared in the direction of flow linking the head () to an elongate body (), the needle valve () being able to move in translation between two end positions including: a deployed end position in which the widest portion of the needle valve head () is downstream from the opening (O) in the direction of the space to be conditioned, the air flow then being laminar and guided by the guiding surface (S) in a divergent flow, a retracted end position in which the widest portion of the needle valve head () is upstream from the opening (O), the air flow then being laminar and guided by the tip () of the needle valve () in a convergent flow.
