OK... So this is my question.
The way I understand, which may not be correct. Is that the HPOP is of fixed displacement. Meaning it always pumps a given amount for a given RPM. Is this correct?
So, taking the RPM's out of the equation, it's like a water hose...Right?
Lets say you have a water hose with the same amount of flow at all times...
There's a nozzle on the end, like the IPR(yellow), and two nozzles branching off, like the oil rails(red).
So... If you want the two
red hoses that are branching off to have LESS pressure, you open the yellow one on the end to get less pressure? And to get more you close the yellow valve?
First of all, is this correct? Or am I way off base? I will ask more questions if it is.
