Abstract

A hermetic compressor for compressing refrigerant comprises a housing including at least a first and second compartment. A motor is mounted in the first compartment and a compression mechanism is located in the second compartment. Gas compressed by the compression mechanism is discharged into the second compartment. A drive shaft operatively couples the motor and the compression mechanism and a lubricating oil sump is formed in the second compartment. A discharge tube is located in the second compartment through which refrigerant gas in the second compartment exits the compressor. The discharge tube includes means for aspirating oil from the oil sump when the oil in the oil sump reaches a particular level.
