Patent

CA 2622274

The present invention relates to a fluid throttle screen (2) for low-noise control of a fluid volume flow rate (Q) in a pipe and the use of such a throttle screen (2) in an aircraft climate control system. In addition, the present invention relates to a climate control system in an aircraft in whose pipe system at least one such throttle screen (2) is installed. The throttle screen (2) according to the present invention comprises multiple friction elements (3) extending longitudinally in the flow direction, which are situated at a distance to one another in such a way that a fluid is throttled continuously over the extension of the fluid throttle screen (2) as a result of friction on the individual friction elements (3).

La présente invention concerne un filtre (2) d'étrangleur de fluide qui assure la régulation à faible bruit d'un débit volumétrique (Q) d'un fluide dans une conduite et l'utilisation d'un tel filtre (2) d'étrangleur dans un système de commande de climatisation d'un aéronef dans le système de tuyauterie duquel est installé un tel filtre (2) d'étrangleur. Le filtre (2) d'étrangleur selon la présente invention comprend plusieurs éléments de frottement (3) qui s'étendent longitudinalement dans la direction du flux et qui sont situés à une certaine distance les uns des autres de manière à ce que l'étranglement d'un fluide se produise de manière continue sur la longueur du filtre (2) d'étrangleur de fluide du fait du frottement sur les éléments de frottement (3) individuels.
