Abstract
A compressor () has a case () and a crankshaft (). The case has a number of cylinders (). For each of the cylinders, the compressor includes a piston () mounted for reciprocal movement at least partially within the cylinder. A connecting rod () couples each piston to the crankshaft. An electric motor compartment () of the case has a stator () and a rotor (). The rotor is mounted to the crankshaft. The case has a wall () between the motor compartment and a crankcase compartment/sump (). The wall bears a feature () for coalescing oil entrained in a refrigerant flow (), which flow exits the gap () between the rotor and the stator to prevent the oil from entering the cylinders.
