Abstract:
A flow regulator in combination with a water pump comprising:a main body installed in line with an inlet pipe of said pump, said main body has a passageway to receive water flowing through said inlet pipe,a sleeve mounted on said top side of said main body and having an interior chamber,an entrance on said main body that allows water to flow from said inlet pipe into said chamber of said sleeve,a control element movably mounted inside said chamber, said control element includes a biasing spring that opposes said water pressure, andan adjusting device that can be moved by a user of said flow regulator to adjust an elastic force of said spring; such thatsaid control element narrows said passageway as said control element moves in response to an increase in a water pressure in said outlet pipe, and said control element widens said passageway as said control element moves in response to a decrease in a water pressure in said outlet pipe, said control element thereby regulating a flow rate in said inlet pipe, andsaid adjusting device controls an equilibrium point of said flow regulator, said equilibrium point being defined by means of said elastic force of said spring.
