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 for a concentrated corrosion inhibitor solution with a semi-permeable osmotic membrane in contact with and separating the inhibitor solution from the coolant in the overflow reservoir. With properly inhibited coolant, the osmotic pressures balance, but if the level of inhibitor in the coolant drops, water passes through the membrane to force inhibitor solution through an overflow tube or opening to mix with the coolant and raise the inhibitor level therein to a predetermined value.
