ABSTRACT:
A pinch valve assembly which includes a pinch lever rotatably mounted in a housing and a head at one end which serves controllably to pinch at least one pressurized fluid carrying tube against a corresponding pinch bar as the lever is turned between two angular positions. In one embodiment a toggle member is pivotally mounted in the housing and has a head positioned to operate the pinch lever between its angular positions, and to cause the pinch lever to snap by an over-center action between its angular position. In a second embodiment, a push-button member is used to operate the pinch lever.
