(FR) BUSE DE VENTILATEUR RÉGLABLE
Abstract
(EN)
There is provided a nozzle comprising a first air outlet and a second air outlet that are oriented in convergent directions, and a valve for controlling the first and second air outlets. The valve comprises one or more valve members that are moveable through a range of positions between a first end position in which the first air outlet is maximally open and the second air outlet is maximally occluded and a second end position in which the first air outlet is maximally occluded and the second air outlet is maximally open. The valve is further arranged such that a size difference between the first air outlet and the second air outlet when the one or more valve members are in the first end position is greater than a size difference between the first air outlet and the second air outlet when the one or more valve members are in the second end position.

L'invention concerne une buse comprenant une première sortie d'air et une deuxième sortie d'air qui sont orientées dans des directions convergentes, et une vanne destinée à réguler les première et deuxième sorties d'air. La vanne comprend un ou plusieurs éléments de vanne qui sont mobiles dans une plage de positions entre une première position d'extrémité, dans laquelle la première sortie d'air est ouverte au maximum et la deuxième sortie d'air est obstruée au maximum, et une deuxième position d'extrémité, dans laquelle la première sortie d'air est obstruée au maximum et la deuxième sortie d'air est ouverte au maximum. La vanne est en outre agencée de telle sorte qu'une différence de taille entre la première sortie d'air et la deuxième sortie d'air lorsque lesdits éléments de vanne se trouvent dans la première position d'extrémité est supérieure à une différence de taille entre la première sortie d'air et la deuxième sortie d'air lorsque lesdits éléments de soupape sont dans la deuxième position d'extrémité.
