US Patent:

57459924, May 5, 1998

Filed:

Jun 7, 1995

Appl. No.:

8/486981

Inventors:

Jean-Luc M. Caillat - Dayton OH
Roger C. Weatherston - Dayton OH
James W. Bush - Sidney OH

Assignee:

Copeland Corporation - Sidney OH

International Classification:

B23P 1500

US Classification:

29888022

Abstract:

A method of making a scroll-type machine particularly suited for use as a refrigerant compressor and incorporating an improved suspension system for the non-orbiting scroll whereby the latter may be pressure biased for the purpose of augmenting tip sealing. The machine also has a modified wrap tip and end plate profile in order to enhance performance, as well as an improved lubrication system for the drive and a baffle arrangement to provide a directed suction inlet. The machine also has an Oldham coupling utilizing a novel ring element which is non-circular and provides for increased thrust-bearing size, or reduced machine size.

Appl. No.:

7/998549

Inventors:

Jean-Luc Caillat - Dayton OH
Roger C. Weatherston - Dayton OH
James W. Bush - Sidney OH

Assignee:

Copeland Corporation - Sidney OH

International Classification:

F04C 1804
F04C 2902
F16C 2304
F16D 304

US Classification:

418 555

Abstract:

A scroll machine has a drive that incorporates radial compliance. The radial compliance is achieved by having the crank pin drive a drive bushing via a flat surface on the crank pin which slidably engages a flat bearing insert disposed in the wall of a bore located in the drive bushing. The bore in the drive bushing is slightly oval in cross-sectional shape to permit relative sliding movement between the crank pin and the drive bushing.

Assignee:

Copeland Corporation - Sidney OH

International Classification:

F04C 1804
F04C 2700

US Classification:

418 551

Abstract:

A hermetic motor compressor includes a shell, first and second scroll members and a closure member extending across a portion of the interior of the shell adjacent one end of the shell to define a discharge chamber. A discharge port in the scroll member located closest to the closure member provides fluid communication between the center of the scroll members and the discharge chamber through an opening in the closure member. A seal member located between the closure member and the scroll member places the discharge port in sealed fluid communication with the discharge chamber.
