Abstract—Pneumatic Booster Valves (PBV), which amplify air pressure without any electricity or air compressor, has commonly applied to facilities such as automobile production lines. However, because PBV is still not efficient enough, Pneumatic Booster Valve with Energy Recovery (PBV-R), which has one additional function that recovers energy, has been proposed and validated by previous studies. Nonetheless, a parametric study of the optimal shape of PBV-R has not been experimentally studied yet. Thus, in this paper, we experimentally investigate performance of PBV-R under various conditions such as a stroke length and an area ratio to find out the optimal parameters of PBV-R and discuss the results by calculations.
