Valve with resilient tubes having constricted portions |
摘要 |
The valve has flexible resilient tubes which respectively communicate with the fluid supply conduits and which are pinched by control members to control fluid flow. Each tube has a reduced-diameter center or neck portion intermediate its ends which is engaged by the control member. The internal cross section of the neck portion is circular when relaxed and when pinched closed does not require any greater cross-sectional space than do the tube ends. Single-control and dual-control embodiments are disclosed. In the dual-control embodiment the two tubes are carried in a single cartridge assembly which is removable as a unit.
