ABSTRACT:
A flow control device for regulating the flow of fluid through a flexible tubing wherein a roller is employed with a grooved surface for incrementally controlling the flow of fluid through the tubing. In order to properly orientate the groove of the roller during its path of travel through the clamp body and over the tubing, a flat segment or interrupted surface portion is provided on the roller and an interfering member is provided in the base of the clamp. In addition, and to improve the efficiency of the clamp, additional features such as a relief surface in the roller, centering lugs for the tubing to position it in the clamp body, as well as circumferential ribs on the roller are provided.
