Abstract
Abstract An adsorbent device including a porous casing containing adsorbent for placement between spaced pipe portions in a refrigerant receiver with the outer edge portions of the casing bearing against the spaced pipe portions, the adsorbent device including a clip having tabs at opposite ends thereof bonded to tabs on opposite sides of the casing, clip portions on the ends of the clip including a first U-shaped portion extending substantially in the direction of the body of the clip for loosely bracketing one of the pipe portions, and a second U-shaped portion extending substantially perpendicularly to the body of the clip for snapping onto the other pipe portion to thereby hold the casing of the adsorbent device between the spaced pipe portions. The clip is oriented relative to the casing so that the clip portion which snaps onto the pipe always extends substantially perpendicularly thereto, regardless of which pipe portion it snaps onto when the pipe portions are not parallel to each other.
