Title
(EN) VALVE
(FR) SOUPAPE
Abstract
(EN)
A rotary valve is provided comprising a valve housing, a valve member positioned relative to the valve housing so as to define a gap, and a compressible member located within the gap. A portion of the valve member is configured to rotate relative to the valve housing so as to vary the width of the gap between the valve member and the valve housing. As the gap width is varied,the compressible member is compressed, which subsequently alters the rate of fluid flow through the valve.In this way,the rate of fluid flow through the valve is controlled based upon the position of the portion of the valve member relative to the valve housing. Unlike known pinch valves, the valve member is configured to move along a length of the compressible member as the portion of the valve member rotates relative to the valve housing.

Une soupape rotative comprend un boîtier de soupape, un élément de soupape positionné par rapport au boîtier de soupape de manière à définir un espace, et un élément compressible situé à l'intérieur de l'espace. Une partie de l'élément de soupape est conçue pour tourner par rapport au boîtier de soupape de façon à faire varier la largeur de l'espace entre l'élément de soupape et le boîtier de soupape. Lorsque la largeur d'espace est modifiée, l'élément compressible est comprimé, ce qui modifie ensuite la vitesse d'écoulement de fluide à travers la soupape. Ainsi, la vitesse d'écoulement de fluide à travers la soupape est contrôlée sur la base de la position de la partie de l'élément de soupape par rapport au boîtier de soupape. A la différence des soupapes à pincement connues, l'élément de soupape est conçu pour se déplacer le long d'une longueur de l'élément compressible lorsque la partie de l'élément de soupape tourne par rapport au boîtier de soupape.
