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.
