ABSTRACT:
A lubricant dispenser has a housing, a piston subdividing the housing into a pair of compartments one of which is generally closed and the other of which is adapted to be connected to a machine to be lubricated, a body of a reactive liquid in the one closed compartment, and a body of a fluent lubricant in the other compartment. The piston is movable against the lubricant body to force same from the housing to the machine. A reactive element in the one compartment can react with the liquid and form a gas when immersed in the reactive liquid to push the piston with the gas against the lubricant body and expel the lubricant from the housing. The reactive element is constituted as a coherent block by a multiplicity of particles of an active substance capable of reacting with the liquid and forming a gas on reaction therewith and a multiplicity of particles intermixed and in electrically conductive engagement with the active particles of a substance that is substantially less reactive.
