Abstract: Apparatus for controlling lubrication of compressed air tools includes a supply container of lubricating liquid and an air flow pipe extending through the container for connection with a source of compressed air. A control device having both liquid and air flow control valves therein is mounted adjacent to the container and a flow throttler in the form of an aperture or venturi disposed in the air flow pipe. Upstream of the flow throttler, a flow line diverts a portion of the air flow through the control device, past the air flow control valve therein, and then back into the container to apply a pressure against the liquid therein. A liquid supply pipe extends from the liquid in the container to the control device and as the air pressure is applied against the liquid, such pressure causes the liquid to flow through the supply pipe and into the control device, past a liquid flow control valve therein, and then back through a flow line which connects to the air flow pipe downstream of the flow throttler. The liquid passing through the downstream flow line thus mixes with the air passing through the throttler of the air flow pipe. Both the air flow control valve and the liquid flow control valve are manually adjustable.
