  • Patent number: 8840729
    Abstract: An air conditioning drain cleaning system with an automated blow-out cycle to clean out an evaporator pan drain pipe. The system has a pneumatic valve assembly, a controller, a float level switch assembly and a plurality of air lines in a manifold for actuating the pneumatic valve assembly and blowing out the drain pipe. The controller directs the system to initiate or repeat a blow-out cycle until the drain pipe is clear. The pneumatic valve assembly bisects the drain pipe to selectively close the pipe for cleaning with a pair of high pressure air shots, one shot toward each pipe end to dislodge a clog. The float level switch assembly signals the controller if the condensate level in the drain pan drops. If the condensate level does not drop, the controller initiates a further blow-out cycle at increased pressures until the line is clear.

  • Patent number: 8770439
    Abstract: Method and device for discharging a fixed amount of liquid which enables to dispense a liquid material with a higher accuracy. The device includes: a decompression valve for reducing the pressure of a compressed gas supplied; a discharging valve for controlling the flow rate of the gas decompressed at the decompression valve; a liquid storing container for discharging liquid from a nozzle by the gas supplied via the discharging valve; and a buffer tank between the decompression valve and the discharging valve that has a volume greater than the volume of the liquid storage container. The invention suppresses the pressure reduction that occurs in the flow path for supplying the compressed gas to the liquid storage container during the operation of the decompression valve by making the flow resistance between the buffer tank and the storage container greater than that between the buffer tank and the decompression valve.

  • Publication number: 20140158242
    Abstract: A pressure supply system for a fresh water system is provided. The pressure supply system includes a water reservoir having a bleed air inlet and a water outlet. The pressure supply system also includes a water pump so as to load water, which is loaded with bleed air pressure, with a further pressure downstream until a predetermined nominal operating pressure range is achieved. As a result, the pressure supply system provides an increased redundancy by pressure generator assemblies which are based on different pressure generation principles.

  • Patent number: 8667977
    Abstract: Methods and embodiments are described for sampling and measuring oxygen concentrations of flowing samples drawn from the ullage of a chemical or fuel tank and from a source of inerting gas used for purging the tank. The sampled flows are drawn with a venturi pump or a pneumatically driven turbine pump and returned to the ullage of the tank. An optical absorption spectrophotometer is used having a diode laser sensor, and both sensor and the pump can be safely located near to the tank. Control systems and apparatus are disclosed for controlling the oxygen level within the ullage of the tank.
