• As the gear pump (1) pushes
out the hydraulic oil, the hy-
draulic oil flows to the front
block under the dumping
valve (3). Then, it passes
through the dumping valve
and auxiliary hydraulic valve
(if equipped) and then flows
to the end cover on the up-
per section. If the spool of
the dumping valve or auxil-
iary hydraulic valve is in the
neutral state, the oil, flowed
into the valve from the end
cover, returns to the oil tank
passing through the carry-
over line of the valve and the
front block. The front block
2
is equipped with the relief
valve which opens when the
oil pressure rises over 155
kgf/cm
order to protect the system.
