ABSTRACT:
In a horizontal rotary compressor the gas passes from the discharge chamber and enters the eccentric shaft bore by passing through an annular space defined between the inlet of the eccentric shaft bore and the discharge end of the oil pickup tube. As a result, a jet pump is created delivering oil from the sump to the axial bore of eccentric shaft bore. Because the eccentric shaft is rotating, oil tends to collect on the walls of the bore and feeds radial lubrication passages which act as centrifugal pumps with the shaft rotating. The discharge flow passing through the eccentric shaft bore impinges upon the shell cover thereby diverting 180.degree. and passes through the annular space between the rotor and stator before being discharged from the compressor.
