Abstract: A scroll compressor includes a compression mechanism contained within a shell. A non-orbiting scroll is supported for axial displacement relative the shell, and includes an end plate having a wrap extending therefrom and a flange having a bore extending therethrough. A guide member is axially fixed relative the shell and extends through the bore in the flange. A first portion of the guide member is disposed within and generally abuts a first circumferential portion of the bore. A second portion of the guide member is disposed within and generally spaced apart from a second circumferential portion of the bore.

Abstract: An axial complaint mounting system for a scroll machine positions the centroid reaction of the mounting system toward the top of a mounting bore extending through the axial compliant scroll member. The mounting system defines a first clearance located near the top of the mounting bore and a second clearance located near the bottom of the mounting bore. The positioning of the centroid reaction for the mounting system is accomplished by designing the second clearance larger than the first clearance.

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.
