When the pump is started oil is drawn
through the suction port "S" via filter
"H" to the suction side of the gearwheel
set "C". From here the gearwheel set
pumps the oil to the pressure side and
at the same time the oil becomes
pressurized. The oil is led to cut-off and
regulating valve "V" which opens when
the set pressure is reached.
The pressure is controlled and kept
constant by regulating valve "V". At the
same time the gearwheel set "C"
distributes the oil through nozzle port
"P" and pump return side "R" via the
shaft seal "F".
The quantity of oil supplied to nozzle
port "P" is determined by the pressure
set on regulating valve "V" and the
nozzle/resistance in the nozzle line.
In 2-pipe-systems excess oil is led
back to the oil tank. In 1-pipe-systems
the by-pass plug "A" must be removed
to give free flow back to the suction
side via return line "G" with return port
"R" closed.
MOUNTING/DISMOUNTING BY-
PASS PLUG
In a 2-pipe-system excess oil is led
back direct to the oil tank. In a 1-pipe-
system the by-pass plug must be
removed so that there is a free passage
back to the suction side through the
return line with the return port closed.
the set value because the piston of the
regulating valve moves towards its closed
position and partially or wholly cuts off
the return oil via port "O".
This can be remedied by
-
reducing the pump pressure
- reducing the capacity, i.e. smaller
nozzle or greater resistance
- changing to a pump with higher
capacity

When the pump is stopped, the pump
output drops and produces a drop in
the oil pressure. The spring in the
regulating valve presses the regulating
piston forward until it seals in port "P".
This cuts off the oil flow to the nozzle
and ensures that the nozzle line is
effectively shut off.
If the pump is overloaded, i.e. more oil
is demanded than the gearwheel is
able to pump under the given conditions,
the oil pressure falls below
