Abstract: A mounting bracket for a compressor. The mounting bracket includes a mounting member and an elongate bracing member. The mounting member is secured to the housing of the compressor has a central support section in substantial registry with the housing. The mounting member includes two legs which extend from opposite ends of the central support section. The first and second legs respectively include first and second distal portions. The bracing member may be secured to the mounting member with two swaged connections. The swaged connections each define an aperture through the bracing member and the mounting member. A method of mounting a compressor is also provided. The method utilizes a mounting bracket having a bracing member which is secured to a mounting member by deforming at least one of the bracing member and the mounting member into engagement with the other of the bracing member and the mounting member.

Abstract: A scroll compressor including an improved fixed scroll member, and in particular, an improved discharge port in the fixed scroll member. In one embodiment, a discharge port extends through the fixed scroll member and includes at least two sections defining different cross sectional shapes or profiles. A first section of the discharge port is in direct fluid communication with the high pressure working pocket between the scrolls, and includes a profile that decreases the stress loading and the stress concentration in the fixed scroll member. A second section of the discharge port includes a profile that improves the flow of working fluid through the discharge port and is shaped for cooperation with the discharge valve assembly.

Abstract: A mounting arrangement for the motor-compressor unit of a compressor, and a method of assembling a compressor, particularly a scroll compressor. A fixed scroll member is attached to the compressor housing by an overlap between an annular shoulder on the fixed scroll member and the upper end of the housing. A crankcase is attached to, and supported from, the fixed scroll member by a plurality of fasteners, and the crankcase rotatably supports a drive shaft and an orbiting scroll member. The drive shaft is fixed to a rotor disposed within a stator, and an end of the drive shaft opposite the crankcase is rotatably supported by an outboard bearing assembly. A plurality of mount brackets are secured to an interior surface of the housing, and a plurality of fasteners extend through the outboard bearing, the stator, and the mount brackets, and are threaded into the crankcase to rigidly secure the foregoing components together.

Abstract: A substantially horizontal compressor including a housing having a main body portion with an open end. An end cap is secured to the main body portion with the end cap being provided with a plurality of apertures. The hermetic terminal body of the compressor is sealably fitted into one of the plurality of apertures located in the end cap. One of the apertures is sealably fitted with a heater well in which a substantially cylindrical heater element is removably received. A third aperture may be provided in the end cap in which a sight glass is sealably secured for checking the oil level in the oil sump. An indentation is formed in the end cap to increase the rigidity of the end cap. The proximity of the terminal assembly and heater well allows the wiring therefor to be part of the same wiring harness.

Abstract: A compressor assembly including a compression mechanism, a motor including rotor and a laminated stator and a shaft is provided. The shaft is operably coupled to the compression mechanism and the rotor. The shaft extends outwardly from the motor opposite the compression mechanism. A bearing support has a central body that rotatably supports an end of the shaft. The bearing support also includes an outer ring and a support structure connecting the outer ring and central body. The outer ring has a plurality of circumferentially distributed bearing surfaces separated by recesses and bears against the laminated stator. Deformations in the laminations of the stator are received in the recesses in the outer ring. A method of supporting a shaft in a compressor wherein a bearing support member bears against a laminated stator and a stator lamination deformingly protrudes into a recess on the bearing support is also provided.
