n: in a chain-andsprocket drive, using a pump to force oil continuously through pipes with holes in them, through nozzles, or through holes in the sprockets. Oil sprays out directly onto the chain with pressure. On some rigs, the oil sprays onto the outside of the chain, and on others onto the inside of the chain. Compare disk lubrication, drip lubrication.

n: in a chain-andsprocket drive, a type of oil bath lubrication in which the chain itself does not pass through the sump, but one or two disks rotating with the sprocket pick up oil from the sump and sling it against a plate, which then feeds it to the top of the lower span. Compare drip lubrication, pressure lubrication.
