    • A chuck 40 includes a body 42 having a plurality of angularly spaced ribs 166, 168 and 170 formed in a forward cylindrical opening 48 thereof. A locking element 236 is movable within a passage 180 of the body 42, and is formed with a defined portion 242 which is extendable from the passage 180, through an inboard peak surface 172 of the rib 166 and into the opening 48. An actuator 44 is coupled to the locking element 236 and is biased by a spring 250 to urge normally the defined portion 242 of the locking element into the opening 48. A bit 62 is formed with a shank 96 with three grooves 100, 102 and 104 extending axially to a free end 112 thereof. A pocket 114 is formed in a base of each of the grooves 100, 102 and 104. The bit 62 can be manually inserted into the opening 48 of the chuck 40 such that the grooves 100, 102 and 104 are located drivingly over at least portions of the ribs 166, 168 and 170, respectively. In addition, the defined portion 242 of the locking element 236 is located biasingly within the pocket 114 to lock the bit 62 with the chuck 40.
    • 卡盘40包括主体42,主体42具有形成在其前向圆柱形开口48中的多个角度间隔开的肋166,168和170。 锁定元件236可在主体42的通道180内移动,并且形成有限定部分242,其可从通道180延伸穿过肋166的内侧峰值表面172并进入开口48.致动器44 联接到锁定元件236并且被弹簧250偏压以将锁定元件的限定部分242通常推入开口48.钻头62形成有柄部96,柄部96具有三个沿轴向延伸的凹槽100,102和104, 其自由端112。 凹槽114形成在每个凹槽100,102和104的基部中。钻头62可以手动地插入卡盘40的开口48中,使得凹槽100,102和104驱动地位于至少部分 分别为肋166,168和170。 此外,锁定元件236的限定部分242偏置地位于袋114内,以使卡盘40与卡盘40锁定。

    • A manifold includes a plurality of inlet passages provided in fluid communication between an inlet and an outlet passage. A housing retains a pressurized gas cartridge in sealed fluid communication with each of the inlet passages. A check valve is located in at least one of the inlet passages. The check valve is biased to a closed position that prevents gas from flowing through the check valve to the inlet of the inlet passage. Thus, gas cannot exit through the inlet when a pressurized gas cartridge is not sealed thereto. The housing retains a viscous product cartridge and forms a gas enclosure separated from a product enclosure by a movable wall. The gas from the pressurized gas cartridges passes into the gas enclosure and generates a force on the movable wall to dispense product from the product cartridge.
    • 歧管包括设置成在入口和出口通道之间流体连通的多个入口通道。 壳体保持与每个入口通道密封的流体连通的加压气体盒。 止回阀位于至少一个入口通道中。 止回阀被偏压到关闭位置,以防止气体流过止回阀到入口通道的入口。 因此,当加压气瓶未被密封到其中时,气体不能通过入口排出。 壳体保持粘稠的产品盒,并形成一个通过活动壁与产品外壳隔开的气体外壳。 来自加压气瓶的气体进入气体外壳,并在可移动壁上产生一个力,从产品盒中分配产品。
