Ian,

the OMP varies the amount of oil going into the valve.

 

I have determined that it just with RPM, and the = throttle lever connection cuts the flow way back at idle,  but at not much = above idle the flow valve is full open.

 

The valve is actually

a mini intake manifold in parallel to the main intake manifold. When the =

rotor sucks the mixture in through the manifold, some of it is going through =

the little vacuum hose and the little hole in the rotor housing picking up =

what oil the OMP got into the valve. This oil is misted into the combustion =

chamber.

If you have no valve, the droplets of oil will only produce an oil sweat at =

the exit in the rotor housing and not doing anything. = Sorry!

 

This is very interesting.  It is the first time I have seen an explanation of = the valves, and it makes sense.  When I got my engine from Atkins, he = said to simple cut off those valves at the injection ports, and block the holes. =
