Water hammer wave is widely applied to test hydraulic components in various areas. A new hydraulic high-pressure impulse generator is presented in this paper in order to provide the standard water hammer wave for long-term usage. A combination of a sleeve and a rotary spool was used to build the impulse generator. and a booster piston was applied to amplify the output pressure. https://bellfordtoysandhobbiers.shop/product-category/games/
