BACKGROUND OF THE INVENTION
The present invention relates to a saddle-type of 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, in many installations a saddle-type of adsorbent unit is utilized in a refrigerant accumulator having a U-shaped return bend pipe for the purpose of adsorbing moisture in the refrigerant. In the past there were numerous ways of securing the saddle-type of adsorbent unit relative to the U-shaped pipe. These ways included tying a band about both adsorbent containers of the saddle-type adsorbent unit and the U-shaped pipe. Another way included mounting the yoke of the saddle-type of adsorbent unit under the U-bend and fastening the outer ends of the individual containers together. An example of this type is shown in U.S. Pat. No. 4,911,739. In another way, a connecting member connected the two containers and the outer ends of the saddle-type of adsorbent unit were mounted on a filter on a U-bend, as shown in U.S. Pat. No. 5,636,525. However, insofar as known, there has been no prior saddle-type of adsorbent unit wherein a strep on one of the containers encircled the other of the containers to maintain the saddle-type of adsorbent unit mounted on a U-bend pipe of a refrigerant accumulator.
BRIEF SUMMARY OF THE INVENTION
It is one object of the present invention to provide an improved saddle-type of adsorbent unit for a U-bend pipe of a refrigerant accumulator in which the mounting structure includes a strap on one of the containers which encircles the other of the containers when the unit is mounted on a U-shaped pipe.
It is another object of the present invention to provide a saddle-type of adsorbent unit as set forth in the preceding object of the invention which can be fabricated in an extremely simple manner and which utilizes only a small portion of the fabric of one container to provide a strap which is used for mounting the adsorbent unit on a U-shaped pipe. Other objects and attendant advantages of the present invention will readily be perceived hereafter.
The present invention relates to an adsorbent unit comprising first and second porous containers, adsorbent in said containers, a yoke connecting said first and second containers, first side edges on said first container, second side edges on said second container, and a strap having ends secured to said second side edges.
The present invention also relates to an improvement 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 first and second adsorbent containers positioned on opposite sides of said first and second pipe portions, a yoke connecting said first and second containers and positioned under said U-bend, first side edges on said first adsorbent container, and a strap on said second container extending about said first container.
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:
