The remainder of the air passes through the needle o, and flows to the OUT side. The differential pressure between the inside of the bowl and the inside of the sight dome w, causes the lubricant inside the bowl into the oil passage !0. The lubricant drips from the dripping tube !1, and lubricates the OUT side. The amount of lubricant is adjusted by the needle o on the front face. Turning the needle clockwise increases the amount of the lubricant, and turning it counterclockwise until fully open shuts off the lubricant. The needle on the side that is not used should be left fully open.
