A gas compressor includes a housing, a separating element in the housing, and a piston guided for movement along the separating element by a drive mechanism between two dead center positions. Gas is compressed in a three-stage compression cycle by the piston in three separate gas chambers arranged in series in the housing. Pressure increases in the gas are easily feasible from very low to very high pressures, for instance from 5 to 400 bar, based on a relatively small installation. The gas compressor includes only a few wear parts for low manufacturing and maintenance costs and for fail-safe operation.

[ I claim:] [1.] A gas compressor, comprising:a housing;a separating element stationarily mounted in and relative to said housing;a piston mounted for movement guided along said separating element between first and second dead center positions;drive means for moving said piston along said separating element between said dead center positions, said drive means including first and second fluid chambers of variable volume and including first and second feed lines in said separating element coupled to said first and second fluid chambers, respectively, said first and second fluid chambers being separated by a seal and being bounded by said separating element and said piston;first, second and third separate gas chambers within said housing about said piston; andconduit means for connecting said first, second and third gas chambers in series;whereby, gas can be compressed in said gas chambers by said piston in a three-stage compression cycle.
