ABSTRACT:
A suction accumulator for the compressor of a refrigeration system is disclosed in which a vertical fluid storage vessel comprises a cylindrical central member and a lower end cap. A disk-shaped dirt trap baffle member includes at its outer periphery a plurality of circumferentially spaced tabs that are clamped between the central housing member and lower end cap. Circumferentially intermediate the tabs are gaps through which liquid refrigerant flows from an active zone above the baffle to a quiet zone therebelow. Within the quiet zone, liquid refrigerant flows from a radially outer region to a radially inner region along a tortuous flow path created by a vertically extending wall comprising a portion of the baffle member. A bleed-through orifice in a gaseous refrigerant flow conduit siphons liquid refrigerant from the radially inner region into the gaseous flow path. Foreign particles suspended in the liquid refrigerant are isolated within the accumulator at various points along the flow path, particularly within the quiet zone.
