ABSTRACT A suction accumulator (10) including a tubular housing (12) defining a liquid storage vessel (15). A conduit (32) is arranged in the vessel (15) and includes a divider plate (34) for forming two fluid flow passageways (36, 38). A plastic transition cap (44) is secured to one end of the conduit (32) to form a connection passage (48) between the two fluid flow passageways (36, 38). A tubular conduit (54) extends from the liquid storage volume through the transition cap member (44) and into the upflow passageway (38) whereby liquid refrigerant is aspirated from the liquid storage volume into the upflow passageway (38). A screen member (58) is provided in the transition cap member (44) to prevent impurities from flowing through the tubular conduit (54) into the upflow passageway (38). In one embodiment, a pair of pressure equalizing vents (84) are integrally molded with the conduit (32) to equalize pressures in the accumulator (10) when the compressor is turned off. In another embodiment, a pressure equalizing vent (101) directly connects the outlet (20) of the accumulator (10) to the liquid storage vessel (15).
