Abstract

1308440 Osmotic membrane GENERAL MOTORS CORP 28 Oct 1971 [30 Oct 1970] 50184/71 Heading B1X [Also in Division F4] The receiver-vaporizer in an ejector-type refrigeration system is divided into two chambers by an osmotic membrane to allow oneway refrigerant flow therethrough. In a preferred form the membrane is a silicone elastomer but it is stated that other elastomers, other plastics and other materials may be used e.g. fluorosilicones, polychloroprenes, acrylonitrilebutadienes, styrenebutadienes, polyisobutylenes, ethylene-propylene polymers, natural or synthetic polyisoprenes, fluorinated elastomers polysulfides, polyacrylates, chlorosulfonated polyethylenes, polyurethanes and polybutadienes. The osmotic membrane may be of planar or tubular form. In the embodiment of Fig. 3 and 4 (not shown) the membranes (230) are generally cylindrical with undulating outer surfaces. Liquid flows through the spaces between outer tubes (228) and the membranes, through the membranes and inner perforated cylinders (231) into central compartments (232).
