ABSTRACT:
A variable-demand flow regulator regulates water flow into a building based on variable water supply and variable demand pressures. When water demand increases downstream of the variable-demand flow regulator, the water pressure decreases on the downstream side of the piston valve and a piston of a piston valve moves in the downstream direction. This results in an increased number of access holes being exposed to water flow, thus allowing a higher flow of water when water demand increases. An adjustable bleeder valve controls the flow characteristics of the regulator by affecting the movement of the piston.
