2. Function
The lubricating pump supplies a set quantity of lubricating oil at high pressure through
the connection (OI) into the lubricating quills (see Fig. 2).
The non-return valve (6, Fig. 2) opens and the lubricating oil comes out of the the
nozzle tip (5) and the lubricating point (LP) as a spray. The lubricating oil flows equally
on to the cylinder liner wall (see also 2124−1 Cylinder Liner and 7218−1 Cylinder
Lubrication).
After a lubrication pulse, the oil pressure decreases and the force of the compression
spring (4) closes the non-return valve (6).
