氣缸內置，驅動力通過斜楔機構傳遞。工作穩定可靠。在加工期間，卡盤通過雙作用單向閥保持壓力。只有在主軸停止時，壓縮空氣才能通過配氣盤和配氣圈供給。

Chuck with built-in cylinder, driving force is transmitted through the wedge mechanism. It is stable and reliable in work. Built in double non-return valves maintain the air pressure during machining. The compressed air feed via distributor ring and profile seals only when the spindle stops.

配氣盤的兩種安裝定位方式：

Two ways of mounting the distributor ring:

1、通過固定軸承和防轉支架，安裝簡便，但必須及時調整和潤滑固定軸承以保證配氣盤處于正確位置。

1、The distributor ring is positioned via fixed bearings and anti-rotation bracket,easy installation but the fixed bearings must be adjusted in time to keep the distributor ring in correct position.

2、使用配氣盤支架，卡盤與配氣盤不接觸。雖然安裝調整復雜點，但維護保養方便經濟。

2、Though a bit difficult for chuck mounting and adjusting , it is easy maintenance and lower cost by means of the distributor ring bracket to avoid any contact with the power chuck.
