Lamda Valve

[Robert Harris]

Perzactly - the valve CAN be used as a component in a fuel pressure regulator.
But - it was simply a bypass valve as part of a complex fuel control system -
not a fuel pressure regulator in the classic sense.  

Looking at one, notice is has a nice clean largish hole all the way thru.  

And yes, I would use and have advocated repeatedly to use the Lambda Valve
whenever a bypass or controllable restriction is needed.  First candidate.  

This valve is a strong candidate for a "Dejection" valve on a Hilborn fueled
302 - simply to trim the over-rich fuel condition at part throttle in
conjunction with EGO

Lezz say you want a nice high pressure injector system with an excellent
spray.  The Lambda will routinely handle up to about 100 psi fuel pressure.

Plumb a tee off a Bosch CIS high pressure pump.   Feed the input of a Lambda
valve.  Run the line to a little finger sized CIS nozzle - aimed to where you
want the fuel injected.  Itty bitty nozzle is far easier to plumb in than big
ugly solenoid combined with nozzle.

The CIS nozzle is a breakover design.  Needs about 30 PSI to start flowing.
This means no drain back when pressure drops - so line stays hydraulic after
shut down instead of piss dribbling into manifold.  Has a nice cone spray -
mechanically atomized to boot by a vibrating pin.

Control is exactly like you would control any solenoid injector - cept you get
a higher pressure range, finer spray and much less mechanical fangling to get
it in place.  

Just a thought.
