Abstract
An integrated filter body and adsorbent unit capable of being integrally fastened together for easy and economical assembly into a refrigerant pressure vessel assembly. The integrated filter and adsorbent unit includes a filter puck, an adsorbent unit mounted to the filter puck, and an integral feature on the filter puck for integrally fastening the adsorbent unit to the filter puck. The adsorbent unit includes a desiccant bag and a flap that has a mounting aperture and a fastening hole extending therethrough. The filter puck includes a disc-shaped body portion and a projection for cooperation with the fastening hole of the adsorbent unit. The projection is displaced to form an enlarged head for trapping the flap of the desiccant bag to the filter puck.
