A refrigerant circuit suction accumulator has an inner copper U-tube with open inlet an outlet ends, a small oil inlet metering orifice formed in the closed tube end, and a threaded connection stud secured to the closed tube end. Formed on an inlet end portion of the U-tube is an integral deflector structure positioned between refrigerant outlet and inlet openings in the tube side wall. The U-tube legs extend through openings in a generally disc-shaped wire mesh filter element adjacent the closed tube end. The U-tube and filter element are disposed within a unitary tubular outer shell formed from a length of seamless copper tubing. In forming the assembly, one end of the outer tube and the U-tube inlet and the outlet ends are passed outwardly through and sealed within the outer tube end holes, the filter element being coaxially press-fitted within the outer tube, and the side wall refrigerant inlet and outlets openings in the U-tube being disposed within the interior of the outer tube. The remaining open outer tube end is then spun closed around and sealed to the connection stud. |
