Abstract
A pinch valve includes a housing, first and second pinch bars, an actuator, a first front roller and a first rear roller. The actuator translates the first and second pinch bars relative to one another along a translation axis to pinch a flexible tube extending through an opening of the housing. The first front roller and the first rear roller are spaced from one another in the direction of a longitudinal axis. The first front roller extends transverse the opening and is positioned longitudinally upstream from the first and second pinch bars and the first rear roller extends transverse the opening and is positioned longitudinally downstream from the first and second pinch bars. The housing includes a first wall bordering the opening. A first plane lying tangent to the first front roller and the first rear roller is spaced inward from the first wall of the housing.
