Abstract
An improved pressure balancer is mounted to a water inlet passage of a mixing faucet. Its improvement is characterized by the adoption of a mixing chamber, defined at one end of a valve control shaft, in which a plurality of upright turbulence rods are disposed, and a pair of identical silencing screens that are fit in the mixing chamber at the same time so as to effectively reduce the operational noise of a faucet. Moreover, a threaded flange is provided next to the rubber diaphragm on a balance rod to allow a compression nut to be mounted to the balance rod with one side thereof in abutment against the diaphragm. Thus, the diaphragm can be protected from being overturned inside out as a result of excessive water pressure applied to the diaphragm in operation.
