2.2 Location of the Cylinder Lubricating Pump
Each cylinder has a lubricating pump (1, Fig. 2) installed on a support on the cylinder
block (11) on the fuel side of the engine. Servo oil, from the servo oil rail at the free
end, operates the lubricating pumps (see 8016−1, paragraph 4 Servo oil system). The
WECS−9520 releases the related control signals.
The lubricating pumps are hydraulically operated. All lubricating pumps are connected
to the servo oil connecting pipe (6). The pressure reducing valve (2) decreases the
servo oil pressure to 60 bar.
For safety, all high-pressure servo oil pipes have double walls. The pressure
transmitter (3) monitors the servo oil pipes. If the pressure decreases, there is a leak.
The pressure transmitter transmits a signal with a failure message to the alarm and
monitoring system (see 0850−1 paragraph 4.7).
