Abstract

A pinch valve for throttling or terminating the flow of a fluid through a pipe or the like. The valve features two cam bodies within an extension of the valve body. An inner cam body is cammed into non-rotational translational movement in a direction towards and away from the flexible and resilient sleeve of the pinch valve by the cam surface of an outer cam body of circular cross-section which is at least partially rotatable by displacement of a turn handle. The handle may be partially turned about the axis of the outer cam body, to partially constrict or throttle fluid flow, or further turned to completely pinch the sleeve shut and totally terminate fluid flow.
