This video aims to give a comparison of both the Plus + Positives & Minus - Negatives of Coil Compression Springs v Belleville Spring Washers within their role in the Regulation of the modern PCP Airgun.
Having designed & manufactured both mass produced & one off special purpose regulators as part of my Product Design job on & off for near 20 years, I can say that both Coil Compression Spring v Belleville Spring Washer have their part to play in the Regulation of your PCP Airgun, Both have Plus + Positives & Minus - Negatives.
I hope that this video doesn't waffle on to much but helps you to understand more the differences between them both.
I also hope that if you have a lathe or access to a lathe & are planning to manufacture your own regulator that the information within this video is of some help. This also goes for you if you are suffering regulator issues upon a production rifle & that this information may help you track down the fault & correct it more easily.
In Summary:
Coil Compression Springs.
Positives + Very Durable & Reliable, Often Easily Trackable Pressure Output & Self Adjustment by the user 'i.e. Adjustment isn't fiddly with micro scopic movements of the adjuster', Due to their Round Section I have never seen any wear / scrapping caused on the inside of regulator body by the Spring, Due to their Power / Pressure to Piston Travel Ratio - The pressure output is not ever really affected by years of use, Easy to Service & Maintain.
Negatives - You can find yourself very limited in design by both the physical size & compression strengths of the conventional coil spring due to manufacturing constraints & so regulators are slightly larger. Also you cannot reach such high regulation pressures with the Coil Compression Springs as you can the Belleville Spring Washers.
Belleville Spring Washers.
Positives + You are not so limited in the size, shape & design of your regulator as you are with a Coil Compression Spring. The physical size can vary enormously & they are idea for use in Very Small Regulator. The Belleville Spring Washers can be selected & stacked in order to give much high Pressure output than can be reached with a conventional Coil Spring.
Negatives -
Often more tricky to adjust & estimate the pressure output unless you have a test reg set up to use, as great pressure variation may take place over a very small adjustment of the Pressure Adjuster Screw (Nut) etc. Can sometimes be a little temperamental on pressure output over time due to wear & tare & also if not kept under some compression force if all air is let out the air reservoir. Can be harder to service & maintain, depending upon the design.
