ABSTRACT:
A suction accumulator for the compressor of a refrigeration system including a disk-shaped dirt trap baffle member spaced from the wall of the vessel to form a gap 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. 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. A cup-shaped porous filter is disposed over the lower end of the conduit for the gaseous refrigerant to filter liquid refrigerant before it flows through the orifice.
