An air tool lubricator which includes a body having an inlet and an outlet for a gas, a top bore, and a lubricant chamber. The first end of a lubricant conduit is coupled in fluid-flowing relation to the lubricant chamber, and the second end of the lubricant conduit is disposed in the outlet of the body and is capable of being coupled to a lubricant line. The lubricant line carries lubricant from the air tool lubricator to an air tool. Located within the lubricant chamber and capable of delivering a predetermined amount of lubricant into the lubricant conduit is a lubricant metering device or injector. Mounted on the body is a reservoir which is capable of holding a liquid lubricant, and which has a priming conduit through which lubricant may be delivered to the bore of the body. A priming pump is mounted on the reservoir and is capable of delivering a predetermined amount of lubricant from the reservoir to the lubricant chamber. The priming pump is used to fill the lubricant line with lubricant. The air tool lubricator is designed to be calibrated to account for manufacturing tolerances.

An air tool lubricator comprising: a body having an inlet and an outlet for a gas, and a bore, the inlet having a first end with an opening and a second end; a reservoir for holding a liquid lubricant, connected to the body and having a priming conduit through which lubricant may be delivered to the bore of the body; a lubricant chamber positioned within the body; a lubricant conduit having first and second ends, the first end coupled in fluid flowing relation to the lubricant chamber, the second end disposed in the outlet of the body; an inlet piston aligned substantially parallel to the opening of the inlet; and a lubricant injector for delivering a predetermined amount of lubricant into the lubricant conduit, responsive to both air flow and forced liquid flow, and located within the lubricant chamber, wherein the injector moves in correspondence to the motion of the inlet piston. A method of calibrating a device for metering a liquid, the device including an adjustment stem and an injector aligned with the adjustment stem, the injector having a pumping motion, movable to a position where the adjustment stem and injector are in contact with one another, and axially moveable in a chamber from a position of minimum stroke to a position of maximum stroke, and having an air piston and a liquid piston movably coupled thereto, the liquid piston movable from a first position, where the air piston and the liquid piston are in contact with one another, to a second position, where the air piston and liquid piston are still coupled to one another, spaced apart from one another, and a gap exists between them, the method comprising the steps of: measuring the size of the gap between the air piston and the liquid piston; determining a position where the injector will have no pumping motion; setting the injector to a position of minimum stroke; and mounting a stopping mechanism on the adjustment stem so as to prevent the adjustment of the injector to the position where it will have no pumping motion.
