    摘要： A two-part axially separable chuck for pneumatic tires characterized by a valve system and lock which prevents separation of its parts while a mounted tire thereon is inflated under air pressure. A normally closed safety valve is disposed downstream from a main air supply and exhaust valve which cannot be opened until after the parts are manually lacked against separation. After being locked against separation, the parts cannot be manually unlocked until after the tire is deflated by opening the exhaust valve. The main valve system may be in the form of a conventional two position supply and exhaust valve with a single actuator or both the supply and exhaust valves may be operated by separate valve actuators. The safety valve is spring loaded to closed position and is manually moved to open position shortly after locking of the parts occurs. A single operating lever controls movement of the lock and opening of the safety valve. Resilient adapter rings are also employed to accommodate tires of various bead diameters and an adjustment is provided for tires of various widths between the beads.

    摘要翻译： 一种用于充气轮胎的两部分轴向可分离卡盘，其特征在于阀系统和锁，其在其上的安装轮胎在空气压力下被充气时防止其部件分离。 一个常闭安全阀设置在主要供气和排气阀的下游，在主要供气和排气阀不能打开，直到零件手动不能分离。 在被锁定以防止分离之后，在通过打开排气阀使轮胎放气之后，部件不能手动解锁。 主阀系统可以是具有单个致动器的常规两位置供排气阀的形式，或者供排气阀可以由单独的阀致动器来操作。 安全阀弹簧加载到关闭位置，并且在部件锁定后不久就手动移动到打开位置。 单个操作杆控制锁定的运动和安全阀的打开。 还采用弹性接头环来容纳各种胎圈直径的轮胎，并且在胎圈之间为各种宽度的轮胎提供调整。
