BACKGROUND OF THE INVENTION
The present invention relates to an improved 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, in the past when a single adsorbent unit was utilized in a refrigerant accumulator having a U-shaped return bend pipe, certain embodiments had to be secured relative to the spaced pipes by means of an external tie or clip which required extra parts and/or additional manipulative steps. It is with overcoming the foregoing deficiencies of certain prior art adsorbent units that the present invention is concerned.
BRIEF SUMMARY OF THE INVENTION
It is the 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 is an integral portion of the adsorbent unit itself. Other objects and attendant advantages of the present invention will readily be perceived hereafter.
The present invention relates to an adsorbent unit for mounting relative to a U-bend pipe of a refrigerant accumulator having spaced pipes and a return bend comprising a porous container, adsorbent in said container, first and second end portions on said container, first and second bands on said first end portion for placement about said spaced pipes with said container located between said first mounting means and said return bend, and second mounting means at said second end of said container for mounting relative to said return bend.
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 pipe portions extending from said return bend along said side wall, 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, first and second bands, inner ends on said first and second bands secured to said first end portion, outer ends on said first and second bands, means securing said outer ends of said first and second bands to each other in looping engagement with said first and second pipe portions, a tab extending outwardly from said second end portion of said container, and an aperture on said tab mounting said second tab on said filter body.
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:
