Abstract: A water heater and thermostatic control device for a lavatory faucet includes a hot water tank having a reservoir and a heating element disposed within the reservoir, the heating element heats ambient temperature water received by the reservoir to produce hot water, a thermal mixing valve configured to mix hot water received from the hot water tank with ambient temperature water to produce mixed temperature water. The water heater and thermostatic control device also includes a shut off valve configured to permit flow of mixed temperature water to the lavatory faucet, wherein the shut off valve includes a diaphragm and an armature assembly, and wherein the diaphragm is configured to permit air to bleed or vent through the shut off valve when the mixed temperature water is not imparting pressure on the diaphragm.

Abstract: A combined water heater and thermostatic control device that combines the functionality of a water heater, thermostat and shut off valve, and may be installed in various aircraft lavatory applications to facilitate installation, consolidate functions, and reduce the probability of leaks. The combined device may include a water tank assembly, a torque motor valve and servo valve assembly, and a shut-off valve assembly. The combined device may also include a temperature control unit that senses water temperature in a water tank assembly and may activate a water heater.

Abstract: A steering valve includes a housing and a spool disposed inside the housing. The housing includes a top plane and a bottom plane, the top plane including an opening of a first port and the bottom plane including an opening of a second port. The spool includes a top plane including a first and second opening corresponding to a third port and a fourth port, one of which is configured to align with the opening of the first port depending on the orientation of the housing. The spool also includes a bottom plane including a first and second opening corresponding to the third port and fourth port, one of which is configured to align with the opening of the second port depending on the orientation of the housing.
