ABSTRACT:
An air valve includes a valve member for attaching to a bladder, and having a bore, and a greater space communicating with the bore for receiving a plug. The plug includes a needle passage to receive an air inflating needle. A protective bonnet is engaged onto the valve member and includes an outer wall member having one or more openings to allow air to flow into and out of the bladder. The protective bonnet has a flexible bottom panel capable of blocking the valve member by the pressurized air in the bladder. The wall member of the protective bonnet is bellows-shaped formed by one or more peripheral bulges and one or more peripheral recesses.
