reverse circulation cavity to circulation. Fluid flows
through the inner passage of the barrel, out the vents in
its lower end, outward and downward deflected toward the
center in a continuous stream, and up through return ports
in the upper end of the barrel. All junk is thus carried
into the barrel above the junk catchers.
