Abstract
An apparatus for clamping flexible tubing employs one or more plungers as clamps. The plungers are reciprocally moveable by means of a rotatable disk cam which has a cam path on one or both of the faces of the disk, the disk cam being mounted to rotate on a shaft of a stepping motor. The plungers may be used to clamp a single tube or a plurality of tubes.
