Abstract
The present invention provides a restrictor for use in a refrigeration system including the method of adapting its use to the system and more particularly to a restrictor that is formed by providing a flattened portion of tubing that is bent to establish a substantially U-shaped restrictor having diverging leg members connected at their apex by an arcuate segment. Means are provided for moving at least one of the leg members relative to the other so that the diameter of the arcuate segment is altered. Altering the diameter of the arcuate segment causes the cross-sectional area of the restrictor passageway in the segment area to change and, accordingly, the refrigerant flow through the restrictor is effectively adjusted to optimize the refrigeration system efficiency.
