<p>A method and apparatus for recharging depleted tennis balls that uses pressurized gas. A recharge pressure vessel includes a cylindrical shell with a closed end and a spaced apart opening top with a connecting wall forming a charging chamber. The vessel may be pivotally secured to a base. A pressure port proximate the open end permits gas entry and exit for charging. The chamber may be filled with any number of discharged tennis balls and then is sealed and charged with high pressure gas such as carbon dioxide. The balls will become sufficiently recharged and the pressure may be released and the recharged balls remove from the vessel.</p> |
