Beschreibung
Zusammenfassung:	An automatic lubricator for chain conveyors with a pivoting arm having a roller contacting the chain and moving between the chain side links to place lubricating nozzles along the chain center line. A magnetic proximity sensor on the pivoting arm activates the fluid pump when the nozzles are in position to deliver lubricating fluid to the chain pins. Improved metering pump apparatus diverts fluid from the metering pump to a fluid return line immediately at the end of a lubrication cycle. The metering pump chamber is then primed for the next cycle. Drippage from the lubrication nozzles is eliminated.
