ABSTRACT:
A compressor assembly is disclosed including a compressor mechanism resiliently mounted within a hermetically sealed housing. The compressor mechanism includes a crankcase having a radially extending mounting flange portion, which is resiliently connected to the housing sidewall at a plurality of circumferentially spaced locations by a plurality of mounting assemblies. Each mounting assembly comprises a rubber bushing received within a hole in the mounting flange, and a threaded stud that extends through a hole in the bushing and engages a threaded hole in a steel block welded to the housing sidewall above the mounting flange. A washer and retaining nut on the bottom of the threaded stud suspendingly support the mounting flange. In this manner, only a peripheral portion of the washer contacts the mounting flange circumjacent the hole therein, thereby minimizing noise transmission to the housing. Lateral movement of the compressor mechanism is absorbed by the bushing.
