Abstract

A thermostatic integrated faucet includes a valve assembly having an upper valve body and a lower valve body defining a mixing chamber therein, the mixing chamber configured to receive hot water through a hot water inlet and cold water through a cold water inlet. The thermostatic integrated faucet further includes a diaphragm assembly fluidly coupled to the mixing chamber, a sensor operatively coupled to the diaphragm assembly, a thermostatic unit disposed within the mixing chamber of the valve assembly, and a cam shaft coupled to the thermostatic unit. The thermostatic unit is configured to control a water temperature within the valve assembly and the cam shaft configured to control a range of the water temperature within the valve assembly. In various embodiments, the thermostatic unit includes a wax actuator configured to engage with the cam shaft and a mixing shuttle coupled to the wax actuator.
