Claim Text:
1. A method for the metered dispensing of a lubricant by a lubricant dispenser that has a lubricant cartridge filled with lubricant, at least one electrochemical gas-generating cell, and an electronic controller operating the gas-generating cell and comprising a microcontroller and a switch that can interrupt current flow through the gas-generating cell, the method comprising the steps of: a) closing a circuit through the gas-generating cell by the electronic controller at adjustable time intervals so as to displace lubricant from the cartridge by a released gas, b) measuring electrical current flowing through the gas-generating cell while the circuit is closed and as the gas is generated and summing over time the total current that has flowed through the gas-generating cell since the circuit has closed, and c) interrupting the circuit whenever the total current that has flowed through the circuit since closing of the circuit has exceeded a predetermined cumulative amount of current.
