In a horizontal rotary compressor (10) the gas passes from the discharge chamber and enters the eccentric shaft bore (40-4) by passing through an annular space defined between the inlet of the eccentric shaft bore (40-4) and the discharge end of the oil pickup tube (34). As a result, a jet pump is created delivering oil from the sump (36) to the axial bore (40-4) of eccentric shaft (40). Because the eccentric shaft (40) is rotating, oil tends to collect on the walls of the bore and feeds radial lubrication passages (40-5, 40-6, 40-7) which act as centrifugal pumps with the shaft (40) rotating. The discharge flow passing through the eccentric shaft bore (40-4) impinges upon the shell cover thereby diverting 180 DEG and passes through the annular space (43) between the rotor (44) and stator (42) before being discharged from the compressor. <IMAGE> |
