    Abstract: Diaphragm interface apparatus to improve a cycle life of a diaphragm are described. An example fluid regulator includes a fluid flow passageway between an inlet and an outlet, where a sensing chamber defines a portion of the fluid flow passageway. A diaphragm senses a pressure in the sensing chamber and a diaphragm interface adjacent the sensing chamber has a curved surface to contact a portion of the diaphragm that moves in response to pressure changes in the sensing chamber. The curved surface affects an amount of stress imparted to the portion of the diaphragm during operation of the fluid regulator.

  • Patent number: 9500288
    Abstract: A slim profile rotary control valve capable of independently modulating fluids into a single heat exchanger from two different and distinct systems that utilize the same type of heat transfer fluid. The valve is capable of monitoring both the supply and return fluid temperatures as well as the mass flow to enable the valve controller to optimize system's energy efficiency. It eliminates the use of multiple valves currently used in a conventional changeover system and automated control of valve positioning works much superior to existing valves. The housing and inner cylinder have tapered profiles to enable rotary sealing between the inlet and outlet ports. The housing has flow characterization profiles machined into the outlet ports thus eliminating the need for characterization disks. The rotary valve has a geometry that allows for a no flow dead zone when no heat exchange is so demanded.

    Abstract: A combined fuel and purge air valve for a turbine engine has an onboard residual fuel reservoir to relieve pressure transients in the fuel circuit during purge air mode operation. The fuel reservoir also operates to effectively seal the fuel circuit with fuel present in the valve chamber by venting any purge air that should happen to leak past the primary seals. A 3-way spool valve controls the transition between start-up and sustained fuel operation modes as well as the purge air operation mode. A movable shuttle controls the communication of the fuel circuit with the fuel reservoir and ensures that the fuel reservoir is open in the purge air mode and closed off in the fuel modes. Pilot air activates the shuttle and spool valve and fuel pressure provides biasing forces. Fuel is distributed through an array of outlet ports, and the valve is cooled by an integral coolant jacket.

    Abstract: A heating assembly for heating a liquid storage tank includes a heat exchanger tank supported in one wall of the storage tank to extend into the storage tank in contact with liquid stored therein. The heat exchanger tank contains a heat exchanger fluid therein which is heated by a burner tube extending through the heat exchanger tank whereby heat is only transferred to the liquid in the storage tank through the heat exchanger fluid. A controller actuates the burner head of the burner tube to maintain temperature of the heat exchanger fluid between upper and lower temperature limits. The operation of the burner head is interrupted in response to temperature of the liquid in the storage tank exceeding an upper limit, or fluid level in the heat exchanger tank being below a lower limit as determined by respective sensors.

  • Publication number: 20140216080
    Abstract: An improved method of supplying pressurized cold gas consistently of predominately N2 and He at low flow rate (typically under 1 g/s) with a desired N2 liquid fraction to an instrument requiring such is disclosed. Pressurized ultra-dry nitrogen gas of a controlled mass-flow rate is cooled inside fine coils bathed in liquid nitrogen to condense it to a vapor fraction less than about 20% and typically under 3%. A second gas stream consisting of predominately nitrogen plus helium, supplied from a controlled pressure, is cooled in a separate set of coils to an exit mean temperature significantly above the temperature of saturated nitrogen vapor in this mixture. The fluid from the first (condensed) mixture is injected into the cooled gas from the second mixture and transferred through a thermally insulated line to the input of the instrument needing a supply of cold gas of a target vapor fraction.
