ABSTRACT:
A lubricant dispenser includes a lubricant container that has an outlet opening for lubricant, a piston disposed in the lubricant container, and a cap connected with the lubricant container, having a device for generating a gas that impacts the piston. The device for gas generation has a gas cell with an electrolyte fluid and electrodes for electrochemical gas generation, a power source, as well as an electrical connection between the power source and the electrodes with a switch. The cap is a plastic injection-molded part produced in one piece, formed from several parts, using the multi-component injection-molding method, which part is made of an outer ring made of insulation material and an insert that forms the gas cell, having two electrically conductive wall regions as electrodes, as well as having an intermediate piece that separates the conductive regions. The insert contains a sponge saturated with electrolyte fluid, and is closed off with a plastic lid.
