You are correct. The spring doesn't actuate the sensorship. I stand corrected.The second spring and ball/seat(component 169) is a bypass for throttle lift to avoid destroying their sensor, per their patent. Is this the swing arm you referenced? The only moving part is the main diaphragm otherwise (once setup).
However, as I laid out, when you ACTUALLY READ. The value that the transducer is reporting to the controller has NOTHING TO DO WITH THE PRIMARY DIAPHRAM SPRING. IT IS MEASURING " Pressure transducer 155 measures the differential pressure (pressure drop) between return reservoir 167 and chamber 168 and outputs a signal to ECM 121 based upon that measurement. "
Both of those are clearly AFTER the primary regulator and certainly on the RETURN SIDE of the entire assembly (not the rail side).
Furthermore, it comes with a "special" A/N adapter (to connect to the return line fitting) that has been specially sized to give the desired medium/mid backpressure (they sell the regulator in an 8 AN version and a 6 AN version). That insert into 168 is crucial for developing a mid level steady state for typical ranges where the regulator will operate with enough flow in the return line to provide some buffering, but not enough to suffer the pumps being overly tasked.
The controller measures pressure differential and it has NOTHING to do with the regulator diaphram and spring. It's a transducer that generates a value that varies according to the pressure delta which is the basis for control. It has NOTHING to do directly with the regulator diaphram. The diaphram is free to actuate as necessary to maintain the rail side pressure, the only thing changing the transducer is how much return flow/back pressure is present.
