Abstract

PURPOSE: To lighten the load of a pump driving motor even in a less faucet flowing time by installing a relief valve to control a part of reflux of the pump delivered water in the detection of the pressure difference of the pump delivery pressure between the intake port side and the delivery side of the pressure reducing valve.
