  • Air-conditioning system accumulator and method of making same
    Patent number: 5419157
    Abstract: An accumulator for use in an air-conditioning system wherein a refrigerant fluid is circulated. The accumulator embodies an enclosed housing defining an internal vapor chamber, an inlet tube, an outlet tube having a vapor inlet end in an upper portion of the vapor chamber, and a baffle member located within the housing between the upper and lower portions and within the vapor chamber to impede the flow of incoming partially vaporized fluid causing it to circulate within the chamber and allowing the refrigerant vapor to rise to the upper portion of the vapor chamber and to flow through the outlet tube. The baffle member is an integral part of the housing, being formed at the open end of one of two cup-shaped housing members and turning inwardly to provide a generally ring-shaped baffle member, with the cup-shaped members being joined at their open ends to complete the enclosed housing.
