FL-42 Injector for oil
FL42-43 injectors are perfectly adapted to lubricate all types of machines with a cyclic sequence. Discharge of each injector is adjustable and it delivers a precise amount of lubricant. A visual indicator pin built into each injector makes it easy to confirm a succesful discharge at any lubrication point.
Pressure from the supply line moves the injector piston forward. This forces a pre-measured amount of lubricant (delivered during the vent stage) out of the discharge chamber outlet. At the same time, lubricant is transferred into the measuring chamber, the indicator stem extends as this chamber fills.
System pressure is vented. The piston rectracts to its original position. This movement allows lubricant stored in the measuring chamber to empty into the discharge chamber; the indicator stem retracts.
