RPL-1 Operation principle
RPL-1 Operation principle
The opening of the nozzle valve is controlled by solenoid valves and oil pressure. The
force of the oil pressure on the piston must exceed the force of the spring. The pressure of
the spring closes the nozzle valve, when the oil pressure stops having effect on the
nozzle valve. The needle valve of the nozzle closes. The needle in the nozzle valve is
complete withdrawn when the oil pressure in the control circuit is approx. 1800 kPa
(approx. 18 bar).

When to change nozzle
When to change nozzle
If the nozzle seems to be functioning improperly, you may clean the nozzle with diesel oil.
If cleaning does not fix the problem, the properties of the nozzle have got worse and the
nozzle has to be changed. The new nozzle has to be of same type as the original.
If there is an oil leak from the hole in the rear cover , change the nozzle or install a repair
kit.
