发明名称 HOT AND COLD WATER MIXING FAUCET HAVING CHECK VALVE
摘要 A faucet housing includes two barrels each having an inlet port for receiving hot and cold water, and an outlet port. A receptacle and two conduits are coupled between the barrels. One of the barrels has a partition for separating the barrel into two spaces and for communicating with the conduits. A casing is disposed in the other barrel and the receptacle and has a bore for receiving a tube and a valve member. One or more check valves are engaged in either or both of the inlet ports of the barrels for preventing backward water flow and for maintaining water pressure in the housing.
