Self-retaining adsorbent unit

An adsorbent unit comprising a porous adsorbent container, a tab on said container, an aperture in said tab, and concave indentations in the side edges of said tab between said aperture and said container.

In a refrigerant accumulator having a housing with a bottom wall and a side wall and a U-shaped pipe with a return bend adjacent said bottom wall and with first and second pipe portions extending from said return bend within said housing and a filter body extending outwardly from said return bend, the improvement comprising a porous adsorbent container, a tab on said container, an aperture in said tab mounting said tab on said filter body, side edges on said tab, and concave indentations in said side edges located between said container and said aperture receiving said first and second pipe portions.

In a refrigerant accumulator having a housing with a bottom wall and a side wall and a U-shaped pipe with a return bend adjacent said bottom wall and with first and second pipe portions extending from said return bend within said housing, the improvement comprising a porous adsorbent container, adsorbent in said container, first and second end portions on said container, first and second tabs extending outwardly from said first and second end portions, respectively, said porous adsorbent container and said first and second tabs including at least portions fabricated of fusible plastic fabric, said first and second tabs including outer portions which are more rigid than said fusible plastic fabric of said container, and said first and second tabs including first and second concave side edges, respectively, between said outer portions of said tabs and said porous adsorbent container whhich receive said first and second pipe portions.

In a refrigerant accumulator having a housing with a bottom wall and a side wall and a U-shaped pipe with a return bend adjacent said bottom wall and with first and second pipe portions extending from said return bend within said housing, the improvement comprising a porous adsorbent container, a tab on said container, an outer end on said tab remote from said container, side edges on said tab, and concave indentations in said side edges between said container and said outer end of said tab receiving said first and second pipe portions adjacent said return bend.

An adsorbent unit comprising a single porous adsorbent container, adsorbent in said container, at least one tab extending outwardly from said container, side edges on said tab, and concave indentations in said side edges.
