Right now I am working a spool valve design. I currently have the designs nearly completed. One question that pops into my mind is "Do I have my spool travelling far enough to produce little to no flow resistance (disreguarding minor head loss due to air turning aournd bends and such)"
My original direction of thought is this: When a poppet or orrafice opens in a spool valve, how far must it open to reach a critical level where the limiting flow factor is the incoming air channel itself? I believe it to be an areal flux sort of balance: where you want the area of the incoming supply channel to equal the area of exit of the opened orrafice. That should produce no restrictions in the flux of air through that part of the system. I am also assuming that when given small radiused edges and a reasonable fluid flow path that minor head losses become negligable.
Is my concept and areal flux balance approach for fluid flow through a valve orrafice correct, or is there some guide/research to critical minimal openings of a valve head to produce negligable flux bottlenecking?
