Abstract: A compressor includes a shell assembly, a muffler plate and a compression mechanism. The shell assembly has a suction chamber and a discharge chamber. The muffler plate is disposed within the shell assembly and separates the suction chamber from the discharge chamber. The muffler plate includes a hub having a circumferentially extending inner portion and a circumferentially extending intermediate portion. The circumferentially extending inner portion defines a discharge passage extending therethrough. The circumferentially extending intermediate portion has a slot formed in a surface thereof. The slot extends at least partially around the circumferentially extending intermediate portion. The compression mechanism is disposed within the suction chamber and provides working fluid to the discharge chamber via the discharge passage of muffler plate.

Abstract: A compressor may include a shell, first and second scroll members, a floating seal, a muffler plate, and a wear ring. The shell defines a discharge chamber and a suction chamber. The floating seal may sealingly engage the second scroll member. The muffler plate defines the discharge chamber and the suction chamber. The wear ring may sealingly engage the muffler plate and the floating seal such that the wear ring, the muffler plate, and the floating seal fluidly isolate the discharge chamber from the suction chamber. The muffler plate may include an axially facing surface that contacts the wear ring. The axially facing surface may include an annular recess. The wear ring may at least partially cover the annular recess. The annular recess may provide clearance between the muffler plate and the wear ring to allow the wear ring to deflect relative to the muffler plate during compressor operation.

Abstract: The present disclosure provides a high-strength thermally insulative partition assembly (e.g., muffler plate) for use in a scroll compressor. The assembly includes at least one metal plate and an insulating region. The insulating region may have at least one insulating material or may be a low-pressure or vacuum chamber. The partition assembly serves to minimize heat transfer between a low-pressure refrigerant on the low-pressure, suction side and a high-pressure, high-temperature refrigerant on the high-pressure, discharge side of the compressor. The insulating region may be sandwiched between multiple metal plates. The insulating region may be coated on the metal plate. The insulating region may also be a preformed component or mask that is coupled to the metal plate via a mechanical interlock system.
