ABSTRACT:
The flow, use, interaction and separation of lubricant and gas flowing through the suction pressure portion of a low-side refrigeration scroll compressor is managed by the use of a drive motor mounting sleeve and a multi-ported frame. The mounting sleeve and frame provide for the direction of oil to surfaces within the low side of the compressor shell which require lubrication as well as the conduct of suction gas to the scroll compression mechanism in a manner which cools the compressor drive motor yet which maintains the respective flows of oil and suction gas sufficiently separate to ensure that excessive amounts of oil are not conducted out of the compressor in the gas which is compressed thereby. Lubrication is enhanced by the use of a vent passage which opens into a relatively lower pressure region within the suction pressure portion of the compressor shell. The vent induces lift and assists in the delivery of oil, upward and through a gallery in the compressor's drive shaft, to the various surfaces in the upper portion of the compressor which require lubrication.
