Mark and all,
The information that I previously gave on the '86 OMP delivery is in
error. After further analysis of the disassembled OMP, I realized
that the delivery rate for the front two ports depends on the DIFFERENCE
between the diameters of the two sections of the pump piston. The result
is that all four of the ports deliver the same flow rate. This would
make the application of this OMP to a three rotor engine more difficult,
in my opinion. Of course I could be wrong about that, too.
I apologize for the mistake.
Steve
