Abstract
An accumulator for receiving a mixture of gaseous and liquid refrigerant fluid and liquid oil from an evaporator in an air conditioning system and for delivering only gaseous refrigerant fluid with oil atomized therein to the compressor. The accumulator has radially spaced telescoped straight lengths of tube to conduct the gaseous refrigerant fluid with oil atomized therein from the interior of the accumulator to the exterior thereof to thus eliminate the conventional U shaped tube for this purpose whereby the diameter of the accumulator may be smaller than the diameter needed to accommodate a U-shaped tube. The inner one of the telescoped tubes conducts gaseous refrigerant fluid from the top of the accumulator to the bottom end of the outer telescoped tube where it picks up oil from the bottom of the accumulator through a bleed port through the wall of the outer tube and then passes unwardly between the tubes to an outlet port at the top of the accumulator.
