Abstract: An automatic lubricator is microprocessor controlled and can be programmed to deliver lubricant to a bearing or the like at selected intervals. A pressure for lubricant delivery in the range of 80-90 psi can be attained in less than a minute, but the bulk of the lubricant is kept under a minimal pressure of about 7 psi to avoid bleeding. Operation of the lubricator rests upon the use of a minor pressure imposed by a spring to force lubricant into the threads of an auger, so that rotation of the auger by a servo motor controlled by the microprocessor then dispenses the lubricant while at the same time providing a mixing action to the lubricant. Provision is also made for automatic shutting off of the lubricator at a preselected temperature.
