Abstract:
A flow regulator for a water pump, working in conjunction with a water pump, having a pump, an inlet pipe conducting an inlet flow of water to said pump, an outlet pipe conducting water with a water pressure, and a container, said flow regulator comprising:a main body with a top side, installed at said inlet pipe and having a passageway for water flowing through said inlet pipe;a sleeve, mounted on said top side of said main body, being rotatable around a main axis, having an inside with a chamber and a lower side extending into said passageway with opposite openings, which are turned in and out of said passageway by rotating said sleeve around said main axis;an entrance on said main body, conducting said water pressure in said outlet pipe to said chamber;a control element, mounted inside said chamber and glidingly movable therein back and forth, thereby narrowing and widening said passageway, respectively, regulating said inlet flow, with said water pressure causing said control element to move within said chamber such that said passageway is narrowed; anda spring, exerting an elastic force on said control element, countering said water pressure, such that when said water pressure decreases said passageway is widened;wherein, by rotating said sleeve around said main axis, said passageway is widened or narrowed, regulating said inlet flow.
