  • Patent number: 5954101
    Abstract: A delivery and storage system for cryogenic fluids features a vehicle mounted dispensing system including a bulk storage tank that feeds cryogenic liquid to a sump containing a pump to pre-cool the pump. The pump feeds cryogenic liquid to another sump containing a meter so as to cool the meter. A valve selectively routes the cryogenic liquid from the meter sump to the bulk storage tank as the meter cools down. When the meter reaches operating temperature, cryogenic liquid is directed through the meter to a dispensing hose. The cryogenic liquid is dispensed into a liquid cylinder. The liquid cylinder features an automatic shut-off device to reduce the flow of the cryogenic liquid into the cylinder when the cylinder is full. The inner shell is held to the outer shell at the top by a combination stainless steel hose and composite cylinder neck. The bottom of the inner shell features a pair of pins which are supported by a strap across the bottom portion of the outer shell interior.

  • Patent number: 5924291
    Abstract: A system delivers cryogenic gas at a high pressure from a supply of cryogenic liquid maintained at a low pressure in a bulk tank. The bulk tank supplies liquid to at least one transfer tank. The transfer tank is pressurized by connecting it to a pressure building tank contaning gas at a high pressure. A heat exchanger is connected in circuit between the transfer tank and the pressure building tank. The transfer tank provides liquid at a high pressure to the heat exchanger so that a vapor is produced. This vapor is fed to the pressure building tank so that the high pressure therein is maintained. The transfer tank provides a high pressure flow of liquid to a vaporizer and a high pressure gas storage tank so that high pressure cryogenic gas may be produced and stored.
