<p>The economizer has an inlet nozzle (5) placed on a spout tap, and an outlet nozzle (7) for discharging the water out of the economizer, where the nozzles define a flow axis (9). A pulse control device reduces or interrupts the water flow when the tap is opened and when a pulse is applied from bottom to top on the outlet nozzle along the flow axis. The control device restores the flow of the water, which initially regulates a control lever of the tap, when another pulse similar to the former pulse is applied from top to bottom on the outlet nozzle.</p> |
