Abstract: Inflation apparatus for hollow flexible wall objects, such as playballs, in which the source of inflation gas or air is normally inoperative until the object to be inflated is moved into engagement with a gas injection needle for energizing the source of inflation gas, and the source of inflation gas is returned to its normally inoperative state upon the object reaching its desired inflated size. Upon the removal of the inflated object the apparatus is returned to a condition where a subsequent object to be inflated can be supplied with the inflation gas.
