Abstract:
There is disclosed a counterweight for a drive shaft designed for use in each of a plurality of rotary machines having different balancing requirements, respectively, said counterweight comprising: a main body having an overall size and shape to fit within each of said plurality of rotary machines; and a recess in said body, said recess being of a volume selected to optimize the total mass of said counterweight for the particular rotary machine for which it is intended. There is also disclosed a method of manufacturing such a counterweight, and a compressor including such a counterweight. 36'

Abstract:
A balancing system for different compressors utilizes a counterweight having a common exterior configuration. The mass of the counterweight is optimized for each compressor by changing the size of a recess located in the counterweight. In one embodiment, the recess is an arcuately shaped recess; and in another embodiment, the recess is a plurality of holes.
Abstract:
A compressor may include a shell assembly, a compression mechanism and a conduit. The shell assembly may include a fitting through which fluid is received from outside of the compressor. The compression mechanism may be disposed within a chamber defined by the shell assembly. The conduit may extend through the chamber between the fitting and a suction inlet of the compression mechanism and transmit at least a portion of the fluid from the fitting to the suction inlet. The conduit may include an inlet that may be spaced apart from the fitting and an outlet that may engage the compression mechanism.
