ABSTRACT:
A faucet for mixing hot and cold water especially for a wash fixture, wash bowl or the like comprises a faucet housing connectable to hot and cold water supply pipes having a mixing or outlet chamber which is connected with a water outlet piece which is a withdrawable shower hose outlet. An aerating device responding to low pressure in the chamber which prevents a reverse suction of dirty water by the faucet is integrated in the faucet housing with the mixing or outlet chamber connected with it. This aerating device at least comprises one closure member pressed at least by the force of gravity into the closed position. The weight of the closure member is so chosen that the closure member is drawn into the open position with a lower pressure in the mixing or outlet chamber and communicates between the mixing or outlet chamber and/or the supply pipes and the atmosphere to supply air to the system.
