Abstract (en)
[origin: US2008179134A1] A muffling apparatus ( 100 ) having a first, muffling segment ( 1010 ) and a second ( 1020 ), non-muffling segment is provided for placement within an oil separator of refrigeration or cooling system, wherein the apparatus has a non-straight shape and a lumen defined therein to allow for noise-creating pressure pulsations/waves to come into contact with absorbing material ( 120 ) of the muffling segment ( 1010 ) in order to attenuate the energy of the pressure waves/pulsations into heat and thus reduce oil separator vibrations caused thereby.
