Claim 4:
5. The adjustable flow restrictor of claim 4, wherein:
adjusting the adjustment screw to retract the shaft thereof relative to the nut decreases the length of the pathway through decreasing the helical flow path between the truncated internal threads of the nut and the external threads of the shaft for the adjustment screw with respect to a number of turns therein, resulting in a decrease in duration of liquid contact with the pathway and frictional energy losses of the liquid as the liquid traverses the pathway and a corresponding increase in the volumetric flow rate of the liquid delivered from the outlet; and
adjusting the adjustment screw to progress the shaft thereof into the nut increases the length of the pathway through increasing the helical flow path between the truncated internal threads of the nut and the external threads of the shaft for the adjustment screw with respect to a number of turns therein, resulting in an increase in duration of liquid contact with the pathway and frictional energy losses of the liquid as the liquid traverses the pathway and a corresponding decrease in the volumetric flow rate of the liquid delivered from the outlet.
