Abstract
A scroll machine has a shell and a muffler plate which defines a muffler chamber and a main chamber. The muffler plate has a face for engaging a seal which is disposed at an interface between the muffler chamber and the main chamber. The muffler plate has a structurally advantageous configuration incorporating a frusto-conical portion and a tubular portion, which reduces distortion of the face and thereby reduces leakage between the muffler and main chambers.
