Noise suppressing refrigeration jumper tube

摘要

A jumper tube for connecting a flow restricting capillary tube and an evaporator in a refrigerator system includes a transition portion in between a cavity portion and a cylindrical portion. The transition portion is crimped and folds a portion of the jumper tube sidewall onto itself to form a passage in the shape of clam shell. The transition portion prevents the creation of popping sounds in the jumper tube due to uncontrolled expansion of refrigerant exiting the capillary tube.
