Abstract
A set of selectable custom water flow restrictors is provided to limit water flow to a predetermined selected gallons-per-minute rate. The restrictor is inserted in-line upstream of the faucet, shower or other water appliance to which water passing through the line is delivered. The restrictor has upstream and downstream chambers connected by a restricting orifice, with the chambers being specially designed to eliminate noise from the restrictor, and to cause the restrictor to be self-cleaning. A downstream water pulse-hammer mitigation disc may be used in conjunction with the main portion of the restrictor in appropriate circumstances.
Claims3
For use upstream of a water dispensing fixture, a flow restrictor for insertion in-line in a water line connected to a water dispensing fixture to restrict the water flow through the line, said restrictor comprising:
- (a) an in-line restrictor body;
- (b) said body having a longitudinal flow passageway and an upstream coupling and a downstream coupling for coupling said body into a water line, said couplings comprising a means to couple the restrictor into a potable water line;
- (c) said body defining an upstream water-receiving chamber and a downstream water passing chamber;
- (d) an orifice of selectable restrictive diameter between said chambers to limit the flow of water in said passageway;
- and
- (e) each of said chambers being radiused substantially spherically adjacent said orifice with a radius substantially equal to the radius of the respective chambers at cross-sections spaced from the spherical portions, said water-receiving chamber and downstream chamber being substantially identical in volume, and said restrictor being reversible such that said upstream coupling can be coupled in a water lien downstream.
