Manual Extract: Boom regeneration

When the boom plunger is operated to the lower side, the plunger moves to the left, and the oil from the pump opens the load check valve and is fed to the cylinder rod side from the feed path.

The bottom side return oil opens the load holding valve poppet and flows through the back pressure check valve and into the tank path, but the pressure is boosted by the back pressure check valve. Part of it opens check valve A and is regenerated on the rod side and part of it opens check valve B and flows through the inside of the plunger and into the foot relief valve through the center bypass path to lower the pump flow.
