Phase 9
The control piston B2 has reached its right
end position. Thereby it opens the connec-
tion duct to the left end of control piston C2
and metering piston C1. The pressurized
lubricant P1 is now located at the left end of
control piston C2 and metering piston C1.
Due to its larger cross-section lubricant P1
first moves metering piston C1 to the right
and then displaces the lubricant enclosed
on the right side of metering piston C1 to
outlet 3.
Phase 10:
As soon as metering piston C1 reaches its
right end position, the pressurized lubricant
P1 moves the control piston C2 (black ar-
row) rightward and additionally displaces
the enclosed lubricant on the right side of
control piston C2 to outlet 3.
The total output of outlet 3 corresponds to
the output of metering piston C1 and control
piston C2.
