Abstract

An improved pinch valve includes a camshaft and associated cam(s) controlling the position of a pivotally-mounted first pinch arm and an opposed, pivotally-mounted second pinch arm. The respective pinch arms are provided symmetrically about a central plane which contains an axis of the camshaft. A spring extends across the central plane and interconnects the respective pinch arms so as to urge both pinch arms towards the central plane. A mechanical advantage lever is provided such that the pinching force is greater than the spring force.
