ABSTRACT:
A pneumatically-operated pump is provided that includes a body having a central bore with a liquid chamber for a slidable piston injector, a chamber for a removable reservoir, and an inlet and outlet for a gas. A priming conduit carries liquid from the reservoir mounted on the body to the injector in the liquid chamber which injects the liquid into a liquid line coupled to a fitting on the pump. The liquid line carries lubricant or other liquid from the pump (e.g., air tool lubricator) to an air tool or other article. A priming pump is mounted on the body and is capable of delivering a predetermined amount of liquid from the reservoir to the liquid chamber. The priming pump is used to fill the liquid line with liquid.
