Claims

[Claims for Utility Model Registration] (1) A fluid passage formed by the inner surface of a tube made of an elastic material is deformed and closed by pinching the tube between a pair of pinching members, and
In a pinch valve that is deformed and opened by the elasticity of the tube when the pinch is released,
A pinch valve characterized in that a pair of restoring auxiliary members are provided that can push the tube from a radial direction perpendicular to the pinching direction by the pinching member when restoring the flow path. (2) The fluid passage formed by the inner surface of the tube made of elastic material is deformed and closed by the tube being pinched by the pair of pinching members;
In a pinch valve that is deformed and opened by the elasticity of the tube when the pinch is released,
A connecting member is provided that connects the tube to each of the pinching members so that the tube can be pulled in a direction opposite to the pinching direction by the pinching member when the flow path is restored and deformed. A pinch valve characterized by:
