Abstract
The invention relates to a method for metered dispensing of lubricants using a lubricant dispenser comprising a reservoir chamber filled with lubricant, a gas generating unit for electrochemically generating gas, a piston acted on by the generated gas for outputting the lubricant from the reservoir chamber, and an electronic control unit for controlling the electrochemical gas generation. According to the invention, the temperature of the lubricant or the environment is measured at time intervals, and an average temperature value is derived from a plurality of measured temperature values. Using stored correction values describing the temperature-dependence of the electrochemical gas generating rate, a control parameter determining the electrochemical gas generation is set for the average temperature value, having the requirement that the gas generating rate at the average temperature value corresponds to the target value that correlates to prescribed dispensing time.
