    • A fully recyclable valve housing adapted for engagement with a neck of a container such as a beer keg, has an inner port 25 for liquid and a concentric outer port 14 for pressurised gas, with openings 21 for admitting pressurised gas into the container. A dip tube 5 is connected to a bottom end fitting 4, communicating with a valve stem 8 within the valve housing. A valve member 6 is arranged to control flow through the concentric ports, and a spring element 7 located about the valve stem 8 urges the valve member upwards to close the ports. The spring element 7 is moulded from a resilient polymeric material and comprises a plurality of C-shaped sections 7a angularly arranged in two interconnected stacks on opposite sides of the valve stem such that movement of the valve member 6 by means of a valve-operating member causes concurrent resilient deformation of all the sections.
    • 适于与诸如啤酒桶的容器的颈部接合的完全可循环的阀壳体具有用于液体的内部端口25和用于加压气体的同心外部端口14,其具有用于将加压气体引入容器的开口21。 汲取管5连接到与阀壳体内的阀杆8连通的底端配件4。 阀构件6布置成控制通过同心口的流动,并且围绕阀杆8定位的弹簧元件7向上推动阀构件以关闭端口。 弹簧元件7由弹性聚合物材料模制而成,并且包括多个C形部分7a,该C形部分7a在阀杆的相对侧上成角度地设置在两个互连的叠层中,使得阀构件6通过阀操作构件 导致所有部分的并发弹性变形。
