Abstract
A muffling apparatus (100) is provided for placement within an oil separator of refrigeration or cooling system, wherein the apparatus has a non-straight shape and a lumen (160) defined therein to allow for noise-creating pressure pulsations/waves to come into contact with absorbing material (110) of the muffling apparatus in order to attenuate the energy of the pressure waves/pulsations into heat and thus reduce oil separator vibrations caused thereby.
