Hydraulic system, components ProFlex
Pressure to the hydraulic system is provided by the
drive system's pump. A pressure limiting valve limits
the maximum system pressure to about 45 bar/
630 PSI.
There is a filter in the hydraulic tank for the pump's
suction pipe.
A hydraulic oil filter of the spin-on type is used to
filter impurities.
The control valve on the ProFlex is a gate valve. The
lever is found in the lever housing to the rear and is
connected to the slider. Pressure supply and
HYDRAULIC SYSTEM
exhaust takes place via the valve block. Hydraulic
oil for the lift cylinder is provided via two hoses. The
hose's nipple for the cylinder's piston side is
equipped with a throttle. Between the slider and the
throttle, there is a mechanically controlled return
valve. The purpose of the rear valve is to contain the
oil so that the cutting unit doesn't lower when the
lever is not activated.
The lift cylinder is a double-action hydraulic cylinder,
and is connected to the lever housing's shaft.
The power steering is described under "Steering" on
page 29.
