ABSTRACT:
A noise suppressing feeder tube for use in a refrigeration circuit is disclosed. A single unitary member having a middle portion flattened to reduce this cross-sectional diameter is disclosed for connecting a capillary tube to the evaporator of a small refrigeration circuit. By forming a unitary piece with a reduced cross-sectional area it has been found that refrigerant noise as is caused during the turbulent flow from the capillary tube to the evaporator may be suppressed.
