Dear List, I've been very interested in the recent discussions about foot pumps including their advantages and disadvantages (thanks to all who posted). One criticism was that foot pumps have a relatively low discharge rate, especially compared to the typical hand pump. It seems to me that the discharge of a pump is influenced by the pump size and stroke length. I expect that relatively large pumps can find a home in most cockpits, so the problem must have to do with stroke. Certainly, the typical hand pump has a long stroke that would be hard to duplicate with your foot travel. Is this then the limitation? Could a foot pump be made to have a higher volumetric output by having some sort of linkage that would amplify the stroke that could be accomplished by foot motion? Any opinions??
