<p>There is provided a fluidic pinch valve system 10 for interrupting the flow of material through a conduit assembly. the fluidic pinch valve system 10 generally includes a substantially rigid valve body 100; an axially extended tube member 200 disposed within the valve body 100; and, an injection mechanism 300 coupled to the valve body 100 for injecting a fluid therein. The valve body 100 includes first and second ends and a wall portion 110 extending therebetween. Within the wall portion 110 is formed a bore extending axially from the first end to the second end. An injection port 140 is formed through the wall portion 110 to be in open communication with the bore. The tube member 200 is disposed within the valve body's bore and is formed having distal first and second sealing portions 120a, 120b and a sidewall portion 210 extending therebetween to define an axial passage. The first and second sealing portions maintain substantially flush engagement, respectively, with the first and second ends of the valve body 100. The sidewall portion 210 includes a flex section that is reversibly collapsible, responsive to a fluidic force imparted thereon, to a pinched configuration in which it is adapted to substantially constrict the axial passage.</p> |
