A vapor compression system having a line for flowing heat transfer fluid, a compressor and a condenser both connected with the line. The vapor compression system also has an expansion device connected with the line for expanding the heat transfer fluid. The expansion device has a housing defining a housing orifice and at least one ball within the housing. The ball forms at least two channels, wherein each channel defines a channel orifice. The effective cross-sectional area of the one channel orifice is greater than the effective cross-sectional area of the other channel orifice. Moreover, the ball is movable between a first position and a second position, wherein the housing orifice is effectively made larger in the first position than in the second position. The vapor compression system also has an evaporator connected with the line for transferring heat from ambient surroundings to the heat transfer fluid.
