no flames please, power steering question

[David Glubrecht]

Actually the way I understood the system might be better stated by that the
trans pump pumped the fluid back to the normal pump rerouting it around the
rack. In this way both pumps are pumping the same direction and just
circulating fluid at realitivly low pressure.  That is the point of the
second pump, to reduce pressure.  As neither pump is devoloping pressure
going down the road, I believe there would less parasitic power loss than
with a standard system.  The check valve would open when the trans pump
started pumping more fluid that the regular pump so that the system would
not devolop reverse pressure on the rack.
