Oil mist lubricator for airline - has replaceable insert nozzle providing selected flow rate from oil drip reservoir

摘要

The oil mist lubricator for pneumatic lines has an insert nozzle (12) which is located in a lateral bore in the air line (1). An oil feed into a sump (20) provides oil to be picked up by the airflow through the nozzle, with an outlet jet at the end of a flexible pipe on the side of the nozzle. The sump provides a safe collecting point for any oil seepage when the airline is not operating, with no danger of over lubricating. The nozzle has a lateral inlet hole (19) to take some air from the pressure side of the insert and duct it through the sump and nozzle. The insert can be replaced by different sizes depending on the rate of lubrication required.
