Vehicle tank filling device for cryogenic fuel

摘要

The device first (D1) and second (D2) accumulator tanks for storing fuels e.g. liquid hydrogen, natural gas. The first tanks are arranged inside the second tanks. The volume of the second tank is equal to or greater than the volume of the tank in the vehicle to be filled. At least one conduit (5,6) for cryogenic media extends between the accumulator tanks and incorporates at least one valve (d). At least one conduit (1,2,4,7) extends between the tank with the smaller volume of the two tanks and the actual tank filling coupling (K). At least one conduit (9) for cryogenic media connects the latter conduit with an external conduit network (10). The second accumulator tank is at least partly insulated in relation to the first accumulator tank.
