Abstract
An air line lubricator for air motors and the like which is self priming and provides a controlled, continuous supply of oil for a limited duration once the air line is pressurized. The lubricator utilizes a unique check seal in combination with a bevelled and stepped piston. The construction further allows the use of a single ball check and deposits the lubricating oil directly into the air stream apart from the air line surface.
