    摘要： A method of reducing the height of a sealed compressor incorporates the use of a non-cylindrical portion of the stator windings on the compressor motor. A non-cylindrical portion provides a space between the sealed housing and the windings that can accommodate an additional component. In one embodiment, the additional component is the electrical connection, and in another embodiment, the additional component is an oil heater. Typically, these components were mounted axially beyond the extent of the motor stator, and thus required additional space. The present invention thus allows a smaller height compressor profile.

    摘要： An improved method of aligning the bearing components within a scroll compressor includes the step of mounting the crankcase to be an interference fit within the center shell, and having a surface abutting a true upper surface of the shell. This ensures that the axis of the bearing in the crankcase is idealized and centered on the center axis of the center shell. At the same time, the lower bearing is mounted on the lower end cap, and is also cut to be concentric with a force fit outer surface of the end cap. This ensures the lower bearing is also centered on the inner periphery of the center shell. Once it is ensured the center shell is true, then it is also thus ensured the upper and lower bearings are aligned on a common axis. An improved lower bearing structure with a reverse taper is also disclosed. In some embodiments, the outer surface to be machined to be concentric with the inner surface is provided by a separate part which is welded to the lower end cap.

    摘要： A valve for selectively allowing the return of oil from a discharge plenum to a suction plenum includes a passage which is selectively opened or blocked by a valve spool. The valve spool sees a pressure from a discharge pressure location upstream of a discharge check valve on one face, and a discharge pressure from a discharge plenum on an opposed face. While the compressor is running, the two pressures should be relatively equal. The face which sees the pressure from the chamber upstream of the check valve is larger than the face which sees the pressure from the discharge plenum. Thus, when the compressor is running, the valve spool is biased to a first position at which it allows oil return from the discharge plenum to the suction plenum. However, upon shutdown of the compressor, the pressure in the chamber upstream of the discharge valve drops. The valve spool will be driven to a second position at which it blocks communication for oil return.

    摘要： An improved compressor incorporates structure for facilitating the alignment of a suction tube with the motor stator windings. In one embodiment, the motor stator is provided with a protective coating such that the refrigerant entering the compressor housing through the suction tube does not damage the motor windings. In another feature, the chamber housing is bumped out in the location where the suction tube is mounted such that the distance between the radially inner end of the suction tube and the radially outer portion of the windings is increased. The above provides better protection for the motor windings in a sealed compressor wherein the suction tube is axially aligned with the motor windings.

    摘要： Several discharge check valve arrangements for scroll compressors move the check valve closer to the discharge port and the compression chambers. This reduces the amount of discharge pressure backflow, and thus reduces the amount of reverse rotation at shutdown. In one type of check valve arrangement, a plug is mounted within a check valve chamber to provide a stop for the check valve. The plug allows the check valve to seat against its valve seat while the compressor is operating to allow gas to flow around the check valve into a discharge plenum. At shutdown, the check valve arrangement is constructed to cause the check valve to rapidly close the discharge port. In other arrangements, the discharge check valve assembly may be mounted in a separator plate as a separate valve plug. This embodiment is similar to an earlier embodiment in the basic operation of the check valve.
