Lubricating oil pressure regulating valve
and safety valve
18.4.1 Description
The pressure regulating valve, see Fig 18-2, is integrated in the
lubricating oil pump module and regulates the oil pressure before
the engine by returning the surplus oil direct from the pressure side
of the pump back to the sump.
This pressure actuates the regulating piston (9) and the spring (8)
is tensioned to balance this force at the required pressure. Thus the
pressure is kept constant in the distributing pipe, irrespective of the
pressure in the pressure side of the pump and of the pressure drop
in the system. By tensioning the spring a higher oil pressure is
obtained.
In engines which are running at varying speeds, the valve is
arranged to give a pressure depending on the speed, according to
operating pressures recommended at various speeds (chapter
01.).
If, for some reason, the pressure should increase strongly in the
pressure pipe, e.g. due to clogged system, the ball (10) will open
and admit oil to pass to the regulating piston (9). This serves as
a safety valve.
18.4.2 Maintenance
1 Dismantle all moving parts.
Check them for wear and re-
place worn or damaged parts by new ones.
2 Clean the valve carefully.
3 Check that no details are jamming
while reassembling.
18.4.3 Adjusting of the lubricating oil pressure
1 Loosen the counter nut (14)
on the adjusting screw.
2 Slowly turn the adjustment screw (5)
in clockwise direc-
tion until the pressure reaches the value mentioned in chapter
01, section 01.1., (can be seen from the engine’s Local Display
Unit (LDU)).
3 Tighten the counter nut.
4 Check the pressure .
