Operation, continuation
Phase 3
Once piston B has reached its left-hand final position, the
junction channel to the right -hand end of piston A is
opened.
The lubricant, which flows from above (white arrow)
moves piston C (black arrow) to the left, causing the lubri-
cant quantity ahead of the left-hand end of piston C to be
dispensed to outlet 5 (dashed arrow).

Phase 4
The channel to the right-hand end of piston D is now open
(black arrow).
The lubricant which is f ed from above (white arrow)
moves piston D to t he left, causing the lubricant quantity
ahead of the left-hand end of piston D to be dispensed out
of the metering device via outlet 3 (dashed arrow).

Phase 5
In phase 4, piston D had opened the junction channel t o
the left-hand end of piston A.
The lubricant flowing in (white arrow) moves piston A to
the right (black arrow), causing the lubricant quantity to be
dispensed to outlet 1(dashed arrow).
In the subsequent distribution sequence, pistons B - D are
moved from the left to the right one after the other.
A complete distribution sequence is finished and a new
cycle can begin.
