Scroll Compressor Construction And Method Of Assembly

US Patent:
5551851, Sep 3, 1996
Filed:
Feb 3, 1995
Appl. No.:
8/385996
Inventors:
John R. Williams - Bristol TN
Scott A. Schultz - Bristol TN
Terry L. Lyons - Blountville TN
Assignee:
Bristol Compressors, Inc. - Bristol VA
International Classification:
F04C 1804
US Classification:
418 551
Abstract:
A scroll compressor having a housing containing a non-orbiting scroll and an orbiting scroll and a crankshaft having an eccentric mounted on the orbiting scroll, the non-orbiting scroll being fixed in operative position on the housing by a plurality of pairs of cooperating, mating key and keyway type components provided on the housing and non-orbiting scroll and mating with predesigned pressure contact, wherein all of the pairs have been mated with substantially equal pressure contact prior to fixing the positions of the pairs on the housing, and wherein the mated pairs allow axial compliance motion of the non-orbiting scroll while providing predetermined resistance to the motion.

Scroll Compressor Having Bearing Structure In The Orbiting Scroll To Eliminate Tipping Forces

US Patent:
6030192, Feb 29, 2000
Filed:
Nov 26, 1997
Appl. No.:
8/979878
Inventors:
Joe T. Hill - Bristol VA
Gene M. Fields - Bristol TN
John R. Williams - Bristol TN
Terry L. Lyons - Bluff City TN
Assignee:
Bristol Compressors, Inc. - Bristol VA
International Classification:
F04C 1804
US Classification:
418 552
Abstract:
A scroll compressor having a housing containing an orbiting scroll and a non-orbiting scroll each having a base formed with a free side and a compression side and having an involute extending generally normally from the compression side, each the involute terminating in an axially outer, substantially planar edge and having a radially outer inlet end and a radially inner discharge end, the scrolls being mounted within the housing in mating arrangement about a center axis of the involutes for relative orbital motion for compressing gas between the base and adjacent side portions of the involutes, the orbiting scroll having special bearing structure for eliminating the laterally directed tipping forces which are generally experienced by the orbiting scrolls of conventional scroll compressors, the bearing structure having a bearing hub integral with the discharge end of the involute of the orbiting scroll, the hub having a cylindrical bore oriented substantially normal to the compression side of the orbiting scroll for rotatably receiving an eccentric shaft section of a compressor crankshaft, bearing means formed axially thru the base of the non-orbiting scroll, a crankshaft having an axial section and an eccentric section, the axial section being rotatably mounted in the bearing and the eccentric section being rotatably mounted in the hub, whereby rotation of the crankshaft will move the orbiting scroll thru an orbit relative to the non-orbiting scroll to thereby generate compression pockets between both the base and the involutes.

Scroll Compressor Having An Axial Compliance Pressure Chamber

US Patent:
5588820, Dec 31, 1996
Filed:
Feb 21, 1995
Appl. No.:
8/391733
Inventors:
Joe T. Hill - Bristol VA
Gene M. Fields - Bristol TN
John R. Williams - Bristol TN
Assignee:
Bristol Compressors, Inc. - Bristol VA
International Classification:
F04C 1804, F04C 2700
US Classification:
418 554
Abstract:
A scroll compressor having a housing, a fixed scroll stationary on said housing, an orbiting scroll nested with the fixed scroll and being mounted on the eccentric of the compressor crankshaft for orbital motion about the longitudinal axis of the compressor, the base of the orbiting scroll having an annular groove formed in the outside or low pressure side thereof, a passage formed through the base of the orbiting scroll and placing the groove in fluid communication with an intermediate section of the pressure continuum for providing an axial compliance force against the base of the orbiting scroll and urging the wrap tips thereof into sealing engagement with the adjacent base of the fixed scroll, an annular seal positioned in the groove and having an annular web provided with a substantially planar contact side positioned in sliding, sealing contact with a sealing surface of housing and having annular elastomeric sealing components slidingly sealed against the walls of the groove to provide an axial compliance pressure chamber which is sealed from ambient pressures.

Oil Management In A High-Side Co-Rotating Scroll Compressor

US Patent:
5421709, Jun 6, 1995
Filed:
May 10, 1994
Appl. No.:
8/240187
Inventors:
Joe T. Hill - Bristol VA
John R. Williams - Bristol TN
Gene M. Fields - Bristol TN
Robert E. Utter - Whitehouse TX
John K. Wollitz - Tyler TX
Assignee:
Alliance Compressors Inc. - Tyler TX
International Classification:
F01L 104
US Classification:
418 556
Abstract:
A high-side co-rotating refrigerant scroll compressor defines a lubricant sump in its discharge pressure portion. Lubricant is directed from that sump, through a passage which is at least partially defined by the shell of the compressor, to the bearings in which the scroll members rotate. Heat carried in the lubricant flowing through the passage is transferred through the compressor shell to the ambient. Subsequent to having lubricated the bearing in which the drive scroll member rotates, lubricant is diverted into a passage defined by the drive scroll member drive shaft and enters the stream of compressed discharge gas flowing therethrough. The lubricant is thereby prevented from entering the suction pressure portion of the compressor where it would otherwise heat compressor suction gas prior to the entry of that gas into the compressor's compression mechanism.

Oil Separation And Bearing Lubrication In A High Side Co-Rotating Scroll Compressor

US Patent:
5421708, Jun 6, 1995
Filed:
Feb 16, 1994
Appl. No.:
8/197084
Inventors:
Robert E. Utter - Whitehouse TX
S. Boyd Wall - Tyler TX
Charles A. Singletary - Whitehouse TX
Gene M. Fields - Bristol TN
Joe T. Hill - Bristol VA
John R. Williams - Bristol TN
Assignee:
Alliance Compressors Inc. - Tyler TX
International Classification:
F01C 104
US Classification:
418 556
Abstract:
A high side co-rotating refrigerant scroll compressor includes a motor disposed vertically above its compression mechanism. The discharge of gas from the compression mechanism is through the drive shaft of the drive scroll member which is rotatably supported at its distal end in an upper bearing. Upper bearing lubrication is accomplished by the disentrainment of oil from the mixture of compressed refrigerant gas and oil discharged from the compression mechanism in the vicinity of the bearing and by the direction of such disentrained oil to the bearing.
