Abstract
Flow-regulating members are described that include a primary channel and a plurality of secondary channels. The primary channel defines a primary channel orifice in the flow-regulating member and the plurality of secondary channels define a plurality of secondary channel orifices in the flow-regulating member. The plurality of secondary channel orifices are located along a common periphery of the flow-regulating member, such that an axis passing through the primary channel orifice intersects a plane containing the common periphery at a unique point. At least two of the plurality of secondary channel orifices have different cross-sectional areas. At least one of the plurality of secondary channels intersects the primary channel. Expansion devices containing these flow-regulating members are also described, as are vapor compression systems containing expansion devices, and methods of operating vapor compression systems.
