Abstract

Constructive arrangement of an acoustic filter for a refrigeration compressor, coupled to a refrigeration system containing a refrigerant gas, said acoustic filter (10) comprising a hollow body (11) defining at least one muffling chamber (14, 15) which carries a gas inlet tube (20) and a gas outlet tube (30), at least one of the parts of gas inlet tube (20), gas outlet tube (30) and hollow body (11) carrying at least one noise absorbing porous element (50) in contact with the refrigerant gas in the interior of the hollow body (11).
