Abstract
A metering faucet assembly includes a metering cartridge valve assembly and a separate mixing control valve having a mixing valve stem that is offset relative to a valve actuator for the cartridge valve assembly and coupled to the valve actuator by a coupling mechanism that allows both the mixing valve and the cartridge valve assembly to be operated by a common operating handle. The coupling mechanism includes a slip gear mechanism that allows reciprocating movement of the operating member of the cartridge valve assembly to operate the cartridge valve and rotational movement of a mixing valve stem to operate the mixing valve. The slip gear mechanism provides an end of travel limit for the mixing valve stem and allows adjustment in the temperature limit of the hot or cold water in the mix.
