079097-BWL AUTOMATIC ADDITION OF A CORROSION INHIBITOR TO A COOLANT SYSTEM BY OSMOTIC PRESSURE Abstract: A device for the automatic addition of a corrosion inhibitor to a cooling system, such as in an automobile engine, utilizing osmotic pressure. The device includes a container (15) for a concentrated corrosion inhibitor solution (32) with a semi-permeable osmotic membrane (28) in contact with and separating the inhibitor solution from the coolant in the over- flow reservoir (13). With properly inhibited coolant, the osmotic pressures balance, but if the level of in- hibitor in the coolant drops, water passes through the membrane to force inhibitor solution through an over- flow tube or opening to mix with the coolant and raise the inhibitor level therein to a predetermined value.
