摘要

An accumulator includes a tank (1), a refrigerant inlet port (7) provided at an upper portion of the tank, a refrigerant outlet port (9) provided at the upper portion of the tank, a dryer unit (2) disposed in the tank (1) at an intermediate portion along a direction of height of the tank, and a separating wall (3) extending upwardly from the dryer unit and dividing an upper inner space (10) of the tank above the dryer unit (2) into an inlet side upper space (10a) located at the refrigerant inlet port (7) side and an outlet side upper space (10b) located at the refrigerant outlet side port (9). The separating wall (3) has a plurality of apertures formed in a scattered state for communicating the inlet side upper space (10a) and the outlet side upper space (10b) each other. The accumulator includes an oil returning tube (4) having a lower inlet opening and an upper outlet opening. The oil returning tube (4) is disposed in the tank (1) such that the lower inlet opening and the upper outlet opening are located at a bottom portion of the tank and at the refrigerant outlet port (9), respectively. <IMAGE>
