  • Pneumatic inflation valve core for inflatable sports ball
    Patent number: 8579744
    Abstract: An inflatable sports ball and its pneumatic inflation valve core are provided. The pneumatic inflation valve core includes a passage penetrating the pneumatic inflation valve core in a lengthwise direction. The passage is provided for receiving an inflation needle which is served for inflating a ball bladder of an inflatable sports ball. When an inflation needle inserts into the passage of the pneumatic inflation valve core, since the pneumatic inflation valve core has adequate length, the pneumatic inflation valve core prevents the inflation needle from piercing through the ball bladder as the ball bladder is flat.
