Title: Filling tank with liquefied gas without purging - esp. for automobiles using liquefied gas fuel
Inventor: GEE DAVID ELLIOT
IPC: F17C6/00
Filed: 1976-03-29
Abstract: Liquefied gas is passed from a first vessel into a second vessel, without the need to purge the vapour from the second vessel. A gas line contg. a releasable coupling is cooled by drawing liquefied gas from the first vessel, pressurising it in a pump and recycling it through the gas line back to the same vessel. The gas line is then broken at the coupling, the first (upstream) part of the line is used to form a connection between the two vessels and the second part of the line is blocked. The liquefied gas is passed from the first vessel to the second through the first part of the line. The first part may be disconnected from the second vessel and reconnected to the second part of the line, and the first stage then repeated to recool the gas line. The method enables the tank to be filled without the need to scavenge vapour from it, since all the connecting parts are already cooled.
