Abstract
An improvement in a flow control device for permitting fine adjustment of flow rates of fluid in tubing and maintaining established rates of flow. The device includes a clamping member pivotally mounted adjacent a clamping surface and a tubing-engaging surface on the clamping member which progressively closes the orifice of tubing as the clamping member is rotated in one direction. Coacting means on the clamping member cooperate with actuating means on a force-inducing member mounted for rotational movement on the body of the device. The coacting means is located at a point from the point of pivotal attachment of the clamping member which is at least twice the distance from the pivotal attachment to the tubing-engaging surface. Thus a large movement at the coacting point translates into a small movement of the tubing-engaging surface and results in fine adjustment of flow rates. Preferably, the device includes a segment of elastomeric tubing which is secured within the device on which the clamping surfaces react.
