Beschreibung
Zusammenfassung:	A sealed compressor includes a cylindrical shell extending along an axis. A compressor pump unit is mounted within a housing defined by the cylindrical shell. An electric motor has an inner rotor and an outer stator. The stator has an outer peripheral surface of a first dimension. The center shell has a nominal inner diameter, greater than the first dimension of the stator. The rotor drives a driveshaft about the axis. The driveshaft is associated with the compressor pump unit. A suction port extends through the center shell to deliver a suction fluid to be compressed by the compressor pump unit. Some of the suction fluid flows into a gap defined between the nominal inner diameter of the center shell and the outer periphery of the stator. The center shell has portions deformed radially inwardly to contact the outer periphery of the stator.
