A spool valve is located within the shell of a hermetic compressor unit and shifted by a solenoid valve to direct the discharge of the compressor through either of two lines through the shell. Depending upon the line used as the discharge line, the compressor is suitable for either heating or cooling and is the equivalent of a reversible compressor. Alternatively, a spool valve can connect the suction line of a compressor to either of two lines extending through the compressor shell.
