    Abstract: A container holding a pressurizing fluid comprises a resilient member to be positioned in the container wall and formed with a valve opening. A plug is positioned in the opening to normally close it, but the resilient member will flex to permit the release of fluid through the valve opening past the plug in response to a predetermined difference between the pressure inside and that outside the container. The container is enclosed within an outer jacket holding a fluid to be dispensed, which is maintained under a constant pressure equal to the pressure of said pressurizing fluid less the pressure required to flex said resilient member.

    Abstract translation: 保持加压流体的容器包括要被定位在容器壁中并形成有阀开口的弹性构件。 插头定位在开口中以通常关闭它,但是弹性构件将弯曲以响应于内部的压力和容器之外的预定的差异而允许通过阀开口的流体通过塞子释放。 将容器封闭在保持要分配的流体的外护套中,所述外护套保持在等于所述加压流体的压力的恒定压力下,减少弯曲所述弹性构件所需的压力。
