Abstract: An apparatus for regulating airflow into a rim mounted vehicle tyre is disclosed. The apparatus has an elongated valve housing (1) with an inlet end (IA), an outlet end (2) and a central portion between the outlet end (2) and inlet end (1A). The outlet end includes a rim insertion portion (3) configured to fit into an aperture in the tyre rim. A piston (8) is disposed within the housing (1). The piston includes a valve member (19). A coil spring (22) acts between the housing (1) and piston (8). In use, the piston (8) is biased to an open position for passage of air into the tyre and is movable against the spring bias under air pressure build up in the tyre to a closed position. At the closed position, the valve member (19) seals against a valve seat (21). The piston (8) and spring (22) are located in the central portion of the housing (1) clear of the rim insertion portion (3). The rim insertion portion (3) is of a reduced size not obstructive to the mounting of the tyre.

Abstract translation: 公开了一种用于调节进入轮辋安装车辆轮胎的气流的装置。 该装置具有细长的阀壳体（1），其具有入口端（IA），出口端（2）和出口端（2）与入口端（1A）之间的中心部分。 出口端包括被配置成装配到轮胎边缘中的孔中的轮辋插入部分（3）。 活塞（8）设置在壳体（1）内。 活塞包括阀构件（19）。 螺旋弹簧（22）作用在壳体（1）和活塞（8）之间。 在使用中，活塞（8）被偏置到打开位置，用于使空气通过到轮胎中，并且可以在空气压力下在弹性偏压下抵抗弹簧偏压积聚在轮胎中至关闭位置。 在关闭位置，阀构件（19）密封阀座（21）。 活塞（8）和弹簧（22）位于壳体（1）的中心部分中，远离边缘插入部分（3）。 轮辋插入部（3）的尺寸减小，不会妨碍轮胎的安装。
