Claim 11:
12. A compressor comprising:
a hermetically sealed housing;
a compression mechanism which is positioned inside the housing;
a magnetic coupling which includes a drive coupling half positioned outside the housing and a driven coupling half positioned inside the housing and separated from the drive coupling half by a separation wall portion of the housing, the drive coupling half being connectable to a prime mover and the driven coupling half being connected the compression mechanism; and
at least one injection port which extends through the housing to a location adjacent an inside surface of the separation wall portion, the at least one injection port being connectable to a source of liquid refrigerant;
wherein during operation of the compressor, liquid refrigerant is communicated through the at least one injection port and evaporated on or adjacent the inside surface of the separation wall portion to thereby cool the separation wall portion.
