bale chamber hydraulic system
11.2 Function of the hydraulic system
The hydraulic control unit is the central control part of the
hydraulic system. Via this control unit the hydr. pressure is
directed through lines to activate functions.
The bale growth in the bale chamber extends the tension
cylinder (H). Hydraulic fluid from the top side of the piston
is pressed through an adjustable pressure valve (K) and
then flows back into the cylinder (H) underneath the piston.
The hydr. control unit directs the hydr. pressure through line
(E and D) to the tailgate cylinders (N). When the tailgate
opens the tension cylinders (H) move freely up. A throttle
non-return valve (Q) in the hydr. system enables a sufficient
flow in order to open the tailgate quickly.
When the tailgate is to close the hydr. pressure is directed
on top of the tailgate cylinder (N): the tailgate closes. Just
before the tailgate is closed the flow valve (T) is connected
in between (little flow) and acts to brake the motion of the
tailgate and at once prevents a sudden depression in the
system.
