ABSTRACT:
A lubricator for pneumatic driven power tools and the like is disclosed which operates on the principle of receiving impact air to pressurize an oil reservoir to provide a metered flow of lubricant in proportion to the amount of air flow in one direction and to bypass the pressure differential created during reverse flow so as to avoid lubricant delivery during reverse flow. The lubricator communicates between a delivery air passageway and a oil reservoir and is provided with parallel passages, one of which extends forward of the other into the air stream to produce a pressure differential.
