Abstract: A vehicle air conditioning system compact suction accumulator-dehydrator adaptable for multiple applications to trap liquid refrigerant flowing from the evaporator. The accumulator comprises a hollow vertically disposed tubular casing, providing top and bottom imperforate wall portions. The casing has an inlet and an outlet located in a side of the casing adjacent its top portion in substantial axial alignment. A generally U-shaped tube is located in the casing chamber with one end having a generally right-angled portion projecting into the outlet in a manner to hangingly support the tube in the chamber. An inverted cup-shaped baffle is supported in spaced relation on the tube other end for positioning in front of the casing inlet to provide a passageway from the inlet through the chamber to the inside of the tube.
