Flow regulator for a water pump

Abstract

A flow regulator for a water pump, comprising a control valve, mounted on an inlet pipe of a water pump. The control valve further comprises a passageway, a chamber, a conduit, and a control element. The passageway allows water to flow through the inlet pipe. The chamber reaches across the passageway. The conduit connects to an outlet pipe of the water pump and transmits water pressure from there through a top end of the control valve into the chamber. The control element is inserted in the chamber, having two ends, at least one of which has an opening connected with the conduit, so that water pressure is applied inside the control element. The control element is further made of elastic material and thus expanded to a varying degree according to the water pressure, causing an effective width of the passageway and consequently water flow through the water pump to vary. This allows to adjust supply of water, as delivered by the water pump, to demand.

1 . A flow regulator for a water pump, comprising a control valve, mounted on an inlet pipe of a water pump, said control valve further comprising: 
 a passageway, allowing water to flow through said inlet pipe;    a chamber, reaching across said passageway;    a conduit, connecting to an outlet pipe of said water pump and transmitting water pressure from said outlet pipe through a top end of said control valve into said chamber; and    a control element, inserted in said chamber, having two ends, at least one of which has an opening connected with said conduit, so that said water pressure is applied inside said control element, said control element further being made of elastic material and thus expanded to a varying degree according to said water pressure, causing an effective width of said passageway and consequently water flow through said water pump to vary, so that supply of water is adjusted to demand.
