Abstract

An electrolytic dispensing device includes a first contractible chamber for receiving a liquid to be dispensed, and a second contractible chamber for receiving a gas to control the rate of dispensing of the liquid from the first chamber. An electrolytic cell generates a gas which is fed to the second chamber to dispense liquid from the first chamber in accordance with the electrical current conducted through the electrolytic cell. The electrolytic cell includes a partition of an ion-permeable, but gas-impermeable, material separating its two electrodes. The partition is effective to permit gas generated at one electrode to be fed to the second chamber, and to block from the second chamber gas generated at the other electrode, and thereby to prevent the formation of a hazardous mixture of gases.
