PROBLEM TO BE SOLVED: To reduce an air compressor noise propagated outside the suction system by lowering the compressor noise occurring with suction pulsation at the non-operation (unloading) of the air compressor by a compact and simple means. SOLUTION: An air compressor suction noise reducing structure (50) is provided with a suction chamber (51) installed between suction pipes (12) making a suction port (11) and a suction system pipeline (2) of the air compressor (10) mutually communicate. The chamber has an inside diameter larger than the inside diameter of the suction pipe. The suction system pipe line and the air compressor suction port mutually communicate via the inside space (55) of the chamber. COPYRIGHT: (C)2005,JPO&NCIPI
