ABSTRACT:
A pinch valve includes a distortable rubber-like valve member, in cylindrical form, positioned within a generally cylindrical housing. The valve member has uniformly spaced projections and grooves which enable the valve member to collapse upon itself forming a complete closure between opposite ends thereof. When the valve member so collapses, the circle defined by the outer areas thereof has a greater radius than the radius of the valve member in the uncollapsed condition. The housing has lobular areas to accommodate the extensions of the collapsed valve member.
