Automatic Greasing System Twin-3
EG1703P03
Phase 3
During pumping phase B grease is pressed into channel B (6). While the grease pressure is built up,
piston (3) is pushed back leftwards, passed channel (8). The grease fills chamber (7) and pushes
piston (4) back to the left. The complete grease volume of chamber (2), left of piston (4), is pressed
through channel (1), piston (3), channel (9) and the secondary grease line (5) to the grease point.
Sphere (10) in the non-return valve is pushed back to clear the path to the secondary grease line.
Figure 2.10 Third phase
After a while, the pressure drops in the primary grease line-B (during the pressure decrease phase
of the greasing cycle). This has no influence on the metering unit.
Phase 4
In this phase the same happens as in phase 2. However chamber (Figure 2.10/7) is now filled with
grease. Piston (4) is pushed to the right while chamber (2) is filled. The complete grease volume of
chamber (Figure 2.10/7) is pressed through channel (8), piston (3), channel (9) and the secondary
grease line (5) to the grease points. Sphere (10) in the non-return valve is pushed back to clear the
path to the secondary grease line.
