ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to an adsorbent unit for use in a refrigerant accumulator of an air conditioning system which contains a U-shaped return bend pipe.
By way of background, an adsorbent unit is utilized in a refrigerant accumulator for the purpose of adsorbing moisture in the refrigerant. In the past, insofar as known, prior devices did not have a rigid clip at one end thereof and a tab at the other end for mounting on the filter housing at the bottom of a U-bend.
BRIEF SUMMARY OF THE INVENTION
It is one object of the present invention to provide an improved single container adsorbent unit for a U-bend pipe of a refrigerant accumulator in which the mounting structure includes a rigid clip at one end thereof for positively engaging the spaced pipes of a U-bend and an apertured tab at the other end thereof for mounting on the filter housing at the bottom of a U-bend.
The present invention relates to an adsorbent unit comprising a porous container having first and second end portions, adsorbent in said container, a rigid clip on said first end portion, a tab on said second end portion, and an aperture in said tab.
The present invention also relates to 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 pipes extending from said return bend within said housing, and a filter body extending outwardly from said return bend, the improvement of an adsorbent unit comprising a porous adsorbent container, adsorbent in said container, first and second end portions on said container, a tab extending outwardly from said first end portion of said container, means on said tab for attachment to said filter, and rigid clip means on said second end portion for attachment to said first and second pipes.
The various aspects of the present invention will be more fully understood when the following portions of the specification are read in conjunction with the accompanying drawings wherein:
