A 3/2-way air solenoid valve (integrated in maintenance unit
HSA-TD 20) is required for the drive of the spring-loaded air
piston.
When the solenoid valve is activated, compressed air enters
the air cylinder (item 2) and displaces the air piston downward.
The working piston (item 3)supplies the lubricant via the check
valve (item 4) to the integrated metering device (item 5).
The metering devices meters the lubricant quantity in two equal
quantities of each 1.1 cm³/stroke.
The pump SAF1 (for 1 pinion) supplies a part of the lubricant
via the external check valve to the outlet. The pump SAF2 (for
2 pinions)supplies both lubricant quantities to the two outlets.

Mode of Operation
The 3/2-way solenoid valve must keep activated at least 3 se-
conds to allow the pressure built up in the system.
Once the solenoid valve has been switched off the spring-
loaded air piston can be put in its initial position and, together
with the working piston, it simultaneously sucks in lubricant
from the barrel.
The pump is ready for the next working cycle.
