Optimization of the critical overlap length of hudraulic distributors regarding cavitation inception

Abstract The present paper is focused on the optimization of overlap length in various types distributors hydraulic systems. It has been shown that this a strong influence cavitation rotating distributors, so its would be beneficial to reduce detrimental effects cavitation, such as noise, vibrations, and instabilities. objective study generalize modelling different determine critical at inception. results show pressure losses other are similar, including slide-valves vast majority confirmed stronger development than distributor rotation speed. A 0.071 mm obtained, below which no significant all speeds. Article Highlights slide-valve can expressed similarly. large development, much larger was there almost for any
