Pneumatic tool lubricant dispenser - has lubricant reservoir built onto air feed and flow from reservoir to feed is via microporous pastille

摘要

The lubricant dispenser for pneumatic tools obtains a steady drip of lubricant into the compressed air feed (5, 6). An oil reservoir (1) is built onto the air feed, and oil flow through the pipe (8) which connects from the reservoir to the air feed is controlled by a microporous pastille. The reservoir takes the form of a moulded cup (1) with a transparant screw cap (2). The cup is mounted on the air feed in a prominent visible position, and the feed traverses the base of the cup. A drilling which aligns normally to the feed connects from the cup (12) to the feed (13). The microporous pastille is held in place by a tubular bolt with a hexagonally socketed head. The rate of oil discharge is adjustable by tightening the bolt onto the pastille.
