  • Patent number: 6287092
    Abstract: A hermetic compressor assembly having a housing having disposed therein an electric motor including a stator and a rotor drivingly attached to a crankshaft having an eccentric portion, and a compression mechanism operatively coupled to the crankshaft eccentric portion. A counterweight is attached to the crankshaft and is made of progressively stamped metal stock material having selectively varying widths between first and second side edges thereof. The counterweight has one of a plurality of weights, each individual weight directly corresponding to a different stock material width. Also, a method for manufacturing compressors having installed therein counterweights of different weights and having substantially identical axial projection profiles, wherein the counterweights are made by a method which includes providing a progressive stamping die, and planar metal stock material having one of a plurality of different widths between first and second opposite side edges.

  • Patent number: 6171077
    Abstract: A hermetic compressor assembly and method of assembling a hermetic compressor. The assembly includes a housing, a compression mechanism, an electric motor in driving communication with the compression mechanism, a plurality of suspension spring supports, and a suspension spring for each. The motor and compression mechanism comprise a subassembly that is installed in the housing. The support has first and second portions and a border between the portions. The first support portion is attached to the housing. The second support portion has an arcuate opening at the border between the portions, such that the second portion can be bent inwardly at this border. The suspension spring extends between the support second portion and the subassembly.
