Anyone have a cross section of the CP3 pump?

Am looking to see if it too has a 'metering valve' on the intake side of the
cylinder head

Ask and you get:



Component list, as per the article this photo comes from:
1. Flange
2. Shaft
3. Polygonal ring
4. Housing
5. Gear pump
6. Overflow valve
7. Low-pressure inlet
8. Metering unit
9. Backflow connector
10. High-pressure connector
11. Plunger
12. Bucket
13. Suction valve
14. High-pressure valve (out to rail)

Thanks again and some more on an old thought

This shows (if to scale) the very or too small cavity for lubing
the cam/followers.

Add that if the 'inlet' to the cavity and the 'outlet' to the cylinder
intake too close to have the rest of the cam/follower cavity stagnant
with 'poor' lube property diesel and you have a very, very poorly lubed
cam/follower which has very high PSI conditions

Then add the other two variables that seems to coincide with failures
#1 H2O and #2 Heat

Both reduce lubricity

Both then creates a better environment for cavitation.
