Patent ID: 7243499

Claim:
A refrigeration system utilizing a refrigeration capillary tube inside a suction tube heat exchanger assembly, said assembly comprising in combination: a. a suction line assembly having: i. an axial cylindrical center suction tube portion, with an outside diameter and opposed ends, each of said opposed ends having a longitudinal slot of a predetermined width, a first predetermined length and a shaped inner end portion; ii. two opposed cylindrical female brazed connectors, each having an outer longitudinal tubular main portion and an inner longitudinal, larger diameter integral sleeve portion of a second predetermined length and an inside diameter exceeding the outside diameter of said center suction tube portion, with the free end of each of said sleeve portions having a shaped recess; b. an axial cylindrical capillary tube, of a predetermined outside diameter, having two ends, said capillary tube being adapted to be inserted into one of said opposed ends of said center suction tube portion and therethrough until each of said two ends of said capillary tube extends from an opposed end of said center suction tube portion, each of said two ends being further adapted to be deformed, by being bent, so as to emerge from said center suction tube portion at locations abutting said shaped inner end portions of said center suction tube portion; and c. each of said braze connectors being adapted for a slip-fit engagement of said inner sleeve portion thereof with one of said opposed ends of said center suction tube portions, with each of said shaped inner end portions of said center suction tube portion longitudinal slots cooperating with an adjacent one of said shaped recesses of said sleeve portions to initially physically contact, locate and then fixedly secure in a pressure tight manner, via a subsequent brazing operation, said deformed end portions of said capillary tube relative to said suction line assembly.
