    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. 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.

    Abstract translation: 转向阀包括壳体和设置在壳体内部的线轴。 壳体包括顶平面和底平面，顶平面包括第一端口的开口，底平面包括第二端口的开口。 阀芯包括顶面，其包括对应于第三端口和第四端口的第一和第二开口，其中一个端口被配置为根据壳体的取向与第一端口的开口对准。 阀芯还包括底平面，其包括对应于第三端口和第四端口的第一和第二开口，其中一个开口被配置为根据壳体的取向与第二端口的开口对准。 壳体构造成围绕线轴旋转，并且壳体的取向确定第一端口是否经由线轴的顶部平面中的第一开口流体地联接到第三端口，而第二端口流体地联接到第四端口 经由阀芯的底平面上的第一开口或第二端口是否经由阀芯的顶部平面中的第二开口流体地联接到第三端口，同时第一端口经由第二开口流体地联接到第四端口 阀芯的底面。

    Abstract: A water heater includes a water tank and a flow-through heating element. The water tank contains heated water. The flow-through heating element is located in the lower portion of the water tank and heats water as water is passed through an interior channel of the heating element. In another configuration, the water heater further includes a recirculation line and the heating element further includes an input end external of the water tank to receive water to be heated and an output end to output heated water into the water tank. The recirculation line transports water from the water tank to the input end of the heating element that is external of the water tank.
