Abstract

A method for filling a high-pressure gas accumulator from a reservoir is provided, comprising: removing the gas from the reservoir, transporting the gas through a gas line to a jet pump coupled to the interior of the high-pressure gas accumulator, and generating a ring flow guided along the inside of the wall of the high-pressure gas accumulator. A high-pressure gas accumulator that is suitable for carrying out the method and has a casing having a heat-sensitive layer on the inside, and has an inlet opening that traverses the casing and the layer, wherein a jet pump coupled to the inlet opening is arranged within the casing, and wherein the jet pump is oriented to generate a guided flow to the wall of the casing opposite the jet pump with deflection therein into a ring flow flowing along the heat-sensitive layer.
