A control valve (400) includes an elastomeric flow tube and an actuator.(122). A plunger is operatively connected the actuator and is situated adjacent the flow tube. A reference surface is positioned generally opposite the plunger such that the elastomeric tube is squeezable between the plunger and the reference surface to control fluid flow through the flow tube. A pressure containing member (430) surrounds at least a portion of the flow tube. The pressure containing member may comprise, for example, a braided sleeve, rings situated about the flow tube, or first (431) and second (432) pressure retaining members sandwiched about the flow tube.
L'invention concerne une vanne de commande (400) comportant un tube d'écoulement élastomère et un actionneur (122). Un piston, fonctionnellement relié à l'actionneur, est situé contigu au tube d'écoulement. Une surface de référence est placée généralement à l'opposé du piston, le tube élastomère pouvant ainsi être pressé entre le piston et la surface de référence de façon à réguler l'écoulement de liquide traversant le tube d'écoulement. Un élément à pression (430), qui entoure au moins une partie du tube d'écoulement, peut comprendre, par exemple, un manchon tressé, des bagues disposées autour du tube d'écoulement, ou des premier (431) et second (432) éléments de retenue de la pression pris en sandwich autour dudit tube.
