Abstract: The invention relates to a sound absorber assembly for encased refrigeration compressors. Two cup-shaped members are slidably and telescopically joined to form a main chamber of selectively variable size. A partition in one of the cup elements divides the main chamber into two sub-chambers and the partition is movable to allow any desired volume ratio between the sub-chambers to be selected. A throttle passage having the opposite ends thereof in respective fluid communication with the sub-chambers is incorporated into or connected to the partition.
