US 7,066,441 B2 · Flow restrictor

Abstract

A device for controllably restricting flow through a resilient tube including a block and a pair of generally J-shaped leg members pivotally mounted to the block. The leg members, when pivoted together, together provide a tube support surface. The block is formed with a bore in which there is a rotatable internally threaded sleeve. A jaw member having a threaded shaft is threadedly mated to the sleeve and a knob is fixedly secured to the sleeve for rotation therewith. Accordingly, rotation of the knob moves the jaw member toward and away from the tube support surface to provide desired compression to a length of resilient tubing captured between the jaw and the tube support surface. By pivoting the leg members away from each other, space is provided for installation of the flow restriction device at any desired point along the length of the tubing.

Dependent claims

A device for controllably restricting flow through a resilient tube, the device comprising:

a block having a bore therethrough along a first axis;
an internally threaded sleeve rotatable within said bore abut said first axis;
a knob outside said block fixedly secured to said sleeve for rotation therewith;
a pair of leg members each being mounted to a respective one of a pair of opposite sides of said block for pivoting movement about a second axis orthogonal to said first axis, said pair of leg members when pivoted toward each other together forming a tube support surface;
and
a jaw member having a head with a surface on a first side shaped substantially complemental to the tube support surface formed by the pair of leg members and a threaded shaft extending from a second side opposite said first side and threadedly mated with said sleeve.
