ABSTRACT:
The invention relates to an apparatus and method for supplying high pressure gaseous fuel from a storage vessel to an internal combustion engine of a vehicle, or for other uses. A reverse cascade fuel supply apparatus for a vehicle comprising: (a) a storage tank for storing high pressure gaseous fuel; (b) an intermediate pressure accumulator for storing high pressure gaseous fuel, connected by a pipe to the storage tank; (c) a high pressure accumulator for storing high pressure gaseous fuel connected by a pipe to the intermediate accumulator and by a pipe to the storage tank; (d) a gaseous fuel compressing intensifier connected by a pipe to the storage tank, the intermediate pressure accumulator and the high pressure accumulator; and (e) a plurality of on-off pressure controlled valves located in the pipes connecting the storage tank, the intermediate accumulator, the high pressure accumulator and the intensifier, for enabling selective pumping to and withdrawal of high pressure gaseous fuel from the storage tank, the intermediate accumulator, the high pressure accumulator, the intensifier or the engine, according to a reverse cascade fuel supply program.
