Abstract: An accumulator includes an axial lower region for the accumulation of liquid refrigerant and an axial upper region for the accumulation of vapor refrigerant. A desiccant bag is disposed within the accumulator for removing moisture in the refrigerant. A U or J-shaped return tube in the accumulator has a lower most portion close to the lower end wall of the accumulator. An oil inlet tube and screen assembly is connected to the return tube at the lower most portion of the return tube. A first end of the oil inlet tube is received within an orifice formed in the bottom of the return tube, while the second end of the oil inlet tube extends axially downwardly toward the lower end wall of the accumulator. A screen assembly surrounds the oil inlet tube to prevent particles from entering the return conduit. The oil inlet tube draws oil practically down to the lower end wall of the accumulator for return to the refrigeration system.
