Abstract
An accumulator-dehydrator for use in an air conditioning system having a delivery tube that has an unobstructed free end for drawing in vaporized refrigerant and an oil pickup tube for drawing in oil and liquid refrigerant into the hollow delivery tube. The hollow delivery tube includes a venturi portion, which creates the draw necessary to pull the oil and liquid refrigerant into the hollow delivery tube. An equalization hole is also provided to prevent a liquid slug from migrating to the compressor, thereby damaging the compressor.
