1. A variable compressor, comprising:

  • a compression chamber;

    a reexpansion area;

    a flow channel between the compression chamber and the reexpansion area;

    a valve member movable between first and second positions, the valve member in the first position allowing flow between the compression chamber and the reexpansion area and the valve member in the second position preventing flow between the compression chamber and the reexpansion area, whereby the compressor operates at a first capacity when the valve member is in the first position and at a second, increased capacity when the valve member is in the second position; and

    a control, associated only with the compressor, for moving the valve member between the first and second positions as a function of an operating parameter of the compressor, whereby the compressor is automatically modulated based on the operating parameter.
