Abstract
A flow restrictor includes a flexible tube held in a housing and a linear actuator connected through an intermediate link to a distal link via a first revolute joint proximate the linear actuator and a second revolute joint connecting the intermediate and distal links. The distal link has a distal end adjacent the flexible tube and the intermediate and distal links are constrained to move such that when the linear actuator moves the first revolute joint toward the linear actuator, the distal end of the distal link is driven into the side of the tube thereby progressively occluding the flexible tube.
