2.axial piston
2
Q
What is an opposed plunger pump
A
Sometimes called radial piston this design uses inlet metering principles
3
Q
What is axial Piston pump
A
Uses sleeve metering system
4
Q
The radial piston pump uses what to pressurize fuel?
A
A cam ring
5
Q
What is sleeve metering? (Axial piston design)
A
The quantity of fuel delivery is determined by depressurization or spilling. A sliding collar on the pump shaft opens and closes a spill port which would end injection
