Air flows through the lubricator from the air inlet, partly directly to the pneumatic machine and partly through the air pipe into the oil chamber, so that the static pressure acts on the oil level in the lubricator. The air forces the oil up into the oil pipe through both the pipe’s opening and the small drilled holes in the pipe. Finally reaching the oil dosage screw . The through-flow pipe is pinched opposite the oil duct, thus increasing the flow rate of compressed air and reducing the air pressure at the mouth of the oil duct . Because of the pressure difference, the lubricating oil is forced out into the through-flow pipe, where the oil is atomized and carried with air via the hose to the pneumatic machine.
The supply of oil can be regulated by using the oil dosage screw to open or close the oil duct
