ABSTRACT:
A noise suppressor for hermetic compressors comprises a one piece elongate damper element twisted in the form of a helix, with adjustable pitch for the noise frequency band that one wishes to damp. The damper element is designed to be inserted in a gas passage duct of small hermetic refrigeration compressors, for the purpose of reducing the noise emitted by the compressor, by the opening and closing movements of the suction valve and by the flow of refrigerant gas.
