The limiting structure forms the middle layer of the spherical body, and is fixedly positioned between a bladder and the body case to limit expansion of the bladder. In general, the bladder has an inflatable spherical body that is positioned inside the limiting structure to provide an inner layer of the spherical body. In order to facilitate inflation (i.e., inflating with air), the bladder usually includes a one-way inflation valve that extends through the limiting structure and the body case, thereby enabling inflation of the bladder from the exterior of the spherical body.
