Abstract
A hermetically sealed reciprocating motor compressor unit including a sealed shell. Discharge gas from the compressor is passed through the motor via suitable flow passages. The top of the motor and the interior surface of the shell define a chamber therebetween. The rotor functions as a centrifuge for separating the high pressure refrigerant gas from oil entrained therein. A substantially oil free vortex is formed encompassing a sector of the chamber defined by sides bearing 45.degree. relative to the vertical center line of the rotor. A refrigerant gas discharge tube connected to the top of the shell is located at any position which falls within the sector defining the vortex.
