Water savings thanks to continuous whirlpool and exfoliation while water passes through the hole, causing loss heads.
When water under certain pressure passes through W.Q.S., pressure head changes to speed head, then back to pressure head, thus you cannot feel any change while using it.
Water energy (kinetic energy and potential energy) in area A goes exfoliated while water passes through holes on the piston, generating loss heads and pressure energy.
This pressure energy presses the piston, which makes the spring shrink.
The shrink spring controls the pipe path of “B” at the end of the housing.
Changes in the width of the pipe path generate pressure loss coefficient (loss heads), automatically controlling water capacity. The spring shrinks according to water energy in area A and controls the width of the end of the housing. And water is flushed always in constant amount.
