In order to generate a highly compressed gas, a multistage high-pressure compressor is used, which has a number of 3 compressor stages ( 10 a, 10 b, 10 c, 10 d). A vortex tube ( 20 a, 20 b, 20 c, 20 d) is connected downstream from these compressor stages ( 10 a, 10 b, 10 c, 10 d). The pressure difference between the pressure line ( 4 ) of the high-pressure compressor and the compressed gas reservoir ( 7 ) to be filled is used for driving, together with an expansion turbine ( 5 ), a pre-compressor ( 2 ) for pre-compressing the gas before entering the first compressor stage ( 10 a). Alternatively, a vortex tube for cooling gas can be mounted between the last compressor stage ( 10 d) and the compressed gas reservoir ( 7 ). The inventive device permits a direct filling of a compressed gas reservoir in order to reach a limit value of the pressure in the compressed gas reservoir at a predetermined limit temperature, said limit value being stipulated according to the technical rules.
