Title (EN) VALVE ASSEMBLY
(FR) ENSEMBLE DE VANNE
Abstract:
(EN) An air conditioning flow control valve assembly comprises a control valve (2), which may comprise a deformable sleeve which may be twisted to effect flow reduction, and a ramp-shaped flow deflecting structure (4) downstream of the valve. The flow-deflecting structure (4) is so located as to be impinged upon by a narrow, powerful jet of air which may issue from the valve when it is in a pinched-off condition and is designed to rapidly disperse the jet without giving rise to substantial noise.
(FR) Ensemble de vanne de contrôle de débit d'air conditionné comprenant une vanne de contrôle (2) pouvant inclure une chemise déformable pouvant être tordue pour réduire le débit, ainsi qu'une structure de déviation de débit (4) en forme de rampe en aval de la vanne. La structure de déviation de débit (4) est située de façon à être frappée par un jet d'air étroit et puissant pouvant sortir de la vanne quand elle est pincée et est conçue pour disperser rapidement le jet sans occasionner de bruit important.
