description An expansion device in a refrigeration chiller defines at least two fixed orifices and employs at least two positionable valve members in order to minimize the overall flow area through the expansion device under a first set of chiller operating conditions, to maximize the overall flow area through the expansion device under a second set of chiller operating conditions and to define a flow area intermediate said minimum and said maximum flow areas when a third set of chiller operating conditions exist.
