A compressor may include a shell assembly, orbiting and non-orbiting scrolls, a bearing housing, a bushing, a damper, and a fastener. The bearing housing includes a first aperture. The bushing may include an axial end abutting the bearing housing. The bushing may extend through a second aperture of the non-orbiting scroll. The bushing may include a third aperture. The damper may be received in a pocket that may be defined by and disposed radially between an outer diametrical surface of the bushing and an inner diametrical surface of the non-orbiting scroll. The damper may be at least partially disposed within the second aperture and may encircle the second portion of the bushing. The fastener may include a shaft portion and a flange portion. The shaft portion may extend through the third aperture and into the first aperture. The flange portion may contact a first axial end of the damper.

Compressor having damped scroll

A compressor may include a non-orbiting scroll, an orbiting scroll, a bearing housing and first and second discrete keys. The non-orbiting scroll may include a first end plate having a first spiral wrap extending therefrom. The orbiting scroll may include a second end plate having a second spiral wrap extending therefrom and meshingly engaged with the first spiral wrap of the non-orbiting scroll. The bearing housing may support the orbiting scroll. Each of the first and second keys may be slidably engaged in first slots formed in the second end plate of the orbiting scroll and slidably engaged in second slots formed in the first end plate of the non-orbiting scroll or third slots formed in the bearing housing.

A scroll compressor may include a shell, a compression mechanism, and a sealing apparatus. The compression mechanism may be contained within the shell and include a compression member. The compression member may include an aperture extending radially there a surface. The sealing apparatus may be contained within the shell and include a first seal member and an actuator. The first seal member may be pivotally supported relative the compression member and may be movable from a first position wherein a sealing portion of the first seal member is in a sealing engagement with the surface and a second position wherein the sealing portion of the first seal member is displaced radially outwardly from the surface. The actuator may be engaged with the first seal member and configured to displace the first seal member from the first position to the second position.
