Abstract
A scroll machine has a muffler which is located between a discharge port located in the scroll assembly and a discharge chamber located in a hermetic shell. The muffler has a top cap which is attached to a partition which defines the discharge chamber. A muffler is attached to the top cap and extends towards the scroll assembly through an opening in the partition. The muffler has a generally cylindrical body with two end caps having a spherical surface. The cylindrical body and the end caps define a plurality of perforations which comprise a specific percentage of the total area of these components.
