Abstract
A pinch valve may use a spring force to close a collapsible tube at a pinch point, and may open with a cam mechanism, which may be controlled using an electric motor. The open and closed positions of the pinch valve may be stable without the use of continuing electrical energy, and electrical energy may be consumed during a change between positions. One arrangement may use multiple tubes in a circular arrangement with a cam that may operate one or more of the valves at a time. The cam mechanism may be driven by an electric motor.
