ABSTRACT:
An air line lubricator comprises a casing having an axially disposed air inlet and outlet, the casing defining a chamber adapted to receive a removable cartridge for a lubricant in such manner that the cartridge is spaced from the inner walls of the chamber to define an air passage between the cartridge and such inner walls, the air passage communicating between inlet and outlet. The cartridge is provided with a discharge port at one end thereof and a piston movable therein towards the other end. In use air entering the casing inlet impinges on the piston to cause the latter to urge lubricant through the discharge port. Discharged lubricant is entrained by air passing through the casing outlet.
