    • 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。
