An inflatable sport ball (10), such as a basketball, a football, a soccer ball, a volleyball or a playground ball, is provided with a self-contained inflation mechanism, or multiple self-contained inflation mechanisms, for inflating or adding pressure to the ball. The mechanism is a pump (5a, 5b, 5c) which is retained inside of the ball and which is operable from outside of the ball to pump ambient air into the ball. The pump additionally contains an integral pressure relief device to selectively relieve the pressure of the ball. Instead or in addition to the pressure relief device, the pump optionally contains a pressure-indicating device (72) to determine the relative pressure of the ball.
L'invention concerne un ballon de sport gonflable, tel qu'un ballon de basketball, un ballon de football, un ballon de soccer, un ballon de volleyball ou ballon de terrain de jeu, comprenant un ou plusieurs m~canismes de gonflage autonomes, destin~s ~ gonfler le ballon ou ~ ajouter de la pression ~ celui-ci. Le m~canisme se pr~sente sous la forme d'une pompe qui est maintenue ~ l'int~rieur du ballon et qui peut fonctionner depuis l'ext~rieur, ce qui permet de pomper l'air ambiant dans le ballon. La pompe contient, de plus, un limiteur de pression int~gr~, destin~ ~ lib~rer la pression de manire s~lective. A la place de ce limiteur de pression ou en plus de ce dernier, la pompe peut contenir ~ventuellement un dispositif d'indication de la pression permettant de d~terminer la pression relative du ballon.
