ES39324U - Pump perfected for absorption refrigerators (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

Improved pump for absorption refrigerators constituted by the combination of a chimney (5) to adapt in it a heat source; the external tube (1) of a liquid temperature exchanger that rises vertically (2) welded in a generatrix of the chimney and that ends up grafting under the top of a circular tube (3) concentric with the chimney and with its plane a little out of horizontality; a tube (4) grafted under the lower part of said inclined circular tube, and which goes down welded to the chimney, and at the end of which a thin tube (7) is grafted, which goes up, welded, along a generator of the fireplace; a tube (9) grafted on top of said circular tube, which rises to go to the condenser of the refrigerator; a wide tube (8), concentric with the chimney and welded at its two ends to it to form, a closed space in the upper part of which ends, grafted, and the said thin tube (7) ends; a tube (10) grafted in the lower part of the closed space or chamber just mentioned, which descends and, when it reaches the vicinity of the circular tube, is continued in a thin tube (11), which, passing through the repeated circular tube, is introduced into the mouth that exists there of the first named tube (2), and continues inside it to constitute, with the continuation (1) of (2), the liquid temperature changer attached to the group, changer temperature that in its path may have loops or turns; and, finally, a thin tube (12) that, starting from the highest part of the aforementioned chamber (8), descends to graft into the tube (9) that is directed to the condenser.
