ABSTRACT:
An improved oil filter unit for attachment to a bight portion of a "J" tube of an accumulator dehydrator includes a rigid, preferably metal pick-up tube or projection. The rigid projection prevents collapse of an extension of a disk held by the oil filter unit during assembly of the oil filter unit to the aperture in the "J" tube. The rigid projection also includes an extended lower end which extends closer to the bottom of the accumulator to allow less oil to be in the accumulator for lubricating the compressor of the air-conditioning system, thereby realizing a significant cost savings compared to prior art accumulators.
