Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a fuel-gas compressor and a fuel-gas compression system provided therewith, in which fuel gas leaking in the casing of the fuel-gas compressor is simply and inexpensively diluted by introducing an incombustible gas in the casing. SOLUTION: An oilless fuel-gas compressor comprises a bottomed cylindrical casing 16 having an opening in one end, a stationary scroll 12 forming a part of the casing 16 by covering the opening, and a swirl scroll 11 facing and meshed with a stationary scroll 12. An incombustible gas IG is introduced from a supply port 14 formed in the casing 16 into an opening 13 in the casing, and discharged from a discharge port 15 formed in the casing 16. Thus, a fuel gas FG flowing in the opening 13 from the compressed opening formed between the scrolls 11 and 12 is diluted with the incombustible gas IG. COPYRIGHT: (C)2003,JPO
