ABSTRACT:
The invention relates to a refrigeration type motor compressor assembly in which an integrated motor compressor unit is resiliently mounted. The motor stator includes a stack of rectangularly shaped laminations with bevelled corners. Stator bolts extend upwardly through the laminations with the bolt heads projecting downwardly from the lower surface of the laminations. The resilient suspension system includes four generally cone shaped spring retaining abutment members attachable from below to the four corners of the stack of laminations. These abutment members have recesses for receiving the bolt heads and collars which extend outwardly beyond the bevelled corners of the stack of laminations. The collars are abuttingly engageable with the inner surface of the casing during lateral movement of the spring mounted motor compressor unit to provide bumper protection for this unit.
