Abstract
An air pressure operated automatic lubricating gun is simplified in its conents and in its assembly to such an extent that this automatic gun can compete economically with manually operated lubricating guns. This improvement has been made possible by locating an air pressure chamber in a main pipe above the high pressure pump and below the air pressure operated motor. The riser pipe for the lubricant is arranged off-center to the central longitudinal axis so as not to interfere with the operation of the centrally located pump piston. The riser pipe passes through the air pressure chamber for a compact assembly. The air pressure supply control means are arranged in the air pressure chamber.
