Abstract:
A flow regulator for a water pump, comprising:a valve body having a first chamber and a second chamber oriented in a first direction, and passageway oriented perpendicular to said chambers; a cylindrical control element glidingly movable in said first chamber, said control element having an inner side with a depression therein; a tube placed in said second chamber and having an inner side with a depression therein; a bottom cap with a threaded hole at a central position therein is placed on said second chamber, said threaded hole receiving an adjusting screw, a spring inserted between said depression of said control element and said depression of said tube and urging said control element in said first direction; and a connecting pipe that transmits water pressure from a supply pipe to said first chamber; wherein said control element is urged inward by said water pressure so as to narrow said passageway, while said control element is urged outward by an elastic force of said spring toward an original position, so that controlled water flow and pressure in said supply pipe are achieved.
