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.

Combined water heater and thermostatic control

A motor driven electromechanical actuator assembly includes a motor assembly having a motor shaft and a gear assembly. The gear assembly includes a plurality of gears with a belt drive that couples the motor assembly to the actuator output shaft. The actuator assembly also includes a position sensor system configured to determine a rotational characteristic of the drive shaft.

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. The housing is configured to rotate around the spool and wherein the orientation of the housing determines whether the first port is fluidly coupled to the third port via the first opening in the top plane of the spool while the second port is fluidly coupled to the fourth port via the first opening on the bottom plane of the spool or whether the second port is fluidly coupled to the third port via the second opening in the top plane of the spool while the first port is fluidly coupled to the fourth port via the second opening on the bottom plane of the spool.
