Claim 0:
1. An adjustable flow restrictor, comprising:
a nut including a first end adapted to receive a liquid therein and a second end;
an adjustment screw being adapted to install into the nut from the second end thereof, the adjustment screw and the nut being configured to define a pathway therebetween, whereby adjustment of the adjustment screw relative to the nut varies the pathway with respect to a length thereof;
a sleeve including a first end and a second end, the sleeve being adapted at the first end thereof to fit over the adjustment screw and mate with the nut at the second end thereof, whereby the nut and the sleeve define a chamber with an outlet;
the nut including a first raised wall and a second raised wall extending from the second end thereof, the first raised wall and the second raised wall being spaced apart about the second end to define the outlet of the chamber and a gap across from the outlet;
the sleeve including a raised wall extending from the first end, whereby, during mating of the sleeve at the first end thereof with the nut at the second end thereof, the raised wall of the sleeve inserts into the gap between the first and second raised walls of the nut such that the raised wall of the sleeve, the first raised wall of the nut, and the second raised wall of the nut define a chamber wall of the chamber that directs liquid received into the chamber from the pathway toward the outlet for delivery therefrom; and
the pathway being adapted to receive therein a liquid conveyed to the nut at the first end thereof and communicate the liquid to the chamber for exit therefrom via the outlet, whereby adjusting the length of the pathway regulates the liquid traversing the pathway with respect to volumetric flow rate such that the liquid exiting the outlet flows therefrom at a desired volumetric flow rate.
