Abstract
An automatic pressurizable lubricant dispenser has a vessel adapted to hold a supply of a fluent lubricant and having one side formed with an outlet adapted to be connected via a conduit to a machine to be lubricated and another open side and a cover engaged over the other side and fitted with a cap fittable snugly like a piston in the vessel and forming with the cover a substantially closed compartment holding a supply of a reactive liquid. The cover is formed with a seat opening into the compartment. A gas-generating cartridge fits into the seat and has an element capable of reacting with the liquid and forming a gas. A removable partition closes the seat and segregates it from the liquid-holding compartment. The cartridge is constructed so as to remove the partition and contact the element with the liquid for generating gas in the compartment and forcing the cap like a piston away from the cover into the vessel to pressurize the fluent lubricant therein.
