Further included is a pressure sensor configured to detect the supply line pressure. Yet further included is a controller in operable communication with the pressure sensor and the fluid source, wherein the controller is configured to modify a flow rate of the inert gas in the supply line upon detection of the supply line pressure exceeding a predetermined pressure limit.

  • 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.
