Patent number: 11927187Abstract: A compressor includes a shell, a bearing housing, an orbiting scroll, a non-orbiting scroll and a spacer. The bearing housing includes a central body and a plurality of arms extending radially outwardly from the central body. Each of the arms has a first aperture. The non-orbiting scroll is meshingly engaged with the orbiting scroll and includes a plurality of second apertures. Each second aperture receives a bushing defining a first longitudinal axis and a fastener defining a second longitudinal axis. The fastener extends through the bushing and into a corresponding one of the first apertures in the bearing housing. The spacer is disposed between the bushing and the fastener of each second aperture and is configured to engage one of the bushing and the fastener to restrict radial misalignment between the first longitudinal axis of the bushing and the second longitudinal axis of the fastener.Type: GrantFiled: June 18, 2021Date of Patent: March 12, 2024Assignee: Copeland LPInventors: Harry B. Clendenin, Dennis D. Pax, Larry L Bingham, Keith J. Reinhart, Nicholas J. Altstadt

Patent number: 11248605Abstract: A compressor includes a shell, a compression mechanism and a fitting. The shell includes an opening and defines a chamber. The compression mechanism is disposed within the chamber of the shell. The fitting is attached to the shell at the opening. Working fluid flowing through the fitting flows to the compression mechanism. The opening is partially defined by a first edge and a second edge. The first edge includes a first planar surface and the second edge includes a second planar surface that faces the first planar surface. A first portion of the fitting extends at least partially into the opening and a second portion of the fitting abuts against the first and second edges.Type: GrantFiled: July 28, 2020Date of Patent: February 15, 2022Assignee: Emerson Climate Technologies, Inc.Inventors: Keith J.

Patent number: 9581161Abstract: A scroll machine can include a shell, a first scroll member, a second scroll member and a valve assembly. The valve assembly can permit intermediate pressure in the shell to flow to an area of suction pressure in the shell. The valve assembly can include a first valve manifold that selectively couples to the shell. A second valve manifold can slidably and non-threadably locate against the first valve manifold. A retainer can couple to the first valve manifold to capture the second valve manifold against the first valve manifold. A valve can selectively connect an intermediate flow exiting the shell through the first and second valve manifolds to a suction flow entering the shell.Type: GrantFiled: October 31, 2013Date of Patent: February 28, 2017Assignee: Emerson Climate Technologies, Inc.Inventors: Larry L.

Patent number: 7988433Abstract: A compressor may include a shell assembly defining suction and discharge pressure regions, first and second scroll members disposed within the shell assembly, and a capacity modulation assembly. The first scroll member may include a first end plate defining a discharge passage, a biasing passage, a modulation port, a first spiral wrap extending from a first side of the first end plate, and an annular hub extending from a second side of the first end plate. The second scroll member may include a second spiral wrap meshingly engaged with the first spiral wrap forming a suction pocket in communication with the suction pressure region, intermediate compression pockets, and a discharge pocket in communication with the discharge passage. A first intermediate compression pocket may be in communication with the biasing passage and a second intermediate compression pocket may be in communication with the modulation port.Type: GrantFiled: April 6, 2010Date of Patent: August 2, 2011Assignee: Emerson Climate Technologies, Inc.Inventors: Masao Akei, Roy J.

Patent number: 7934914Abstract: 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.Type: GrantFiled: May 21, 2008Date of Patent: May 3, 2011Assignee: Emerson Climate Technologies, Inc.Inventors: Keith J Reinhart, James A Schaefer, Eric P Cavender

Patent number: 6709247Abstract: A compressor is driven by a drive shaft rotatably supported by a main bearing housing and a lower bearing housing. The main bearing housing positions a main bearing at or near a nodal point of the drive shaft during vibration by the drive shaft. The main bearing housing is designed such that the main bearing pivots during the vibration of the drive shaft in order to maintain surface contact between the bearing and the drive shaft to eliminate edge loading of the bearing.Type: GrantFiled: December 16, 2002Date of Patent: March 23, 2004Assignee: Copeland CorporationInventors: Harry B.
