    Abstract: PURPOSE:To prevent a rapid closing of a poppet valve caused by a dynamic pressure by a method wherein liquid is filled in a liquid chamber in a bearing cylinder. CONSTITUTION:When a poppet valve 5 is opened, a large diameter upper part (c) of a valve shaft 6 is positioned above a liquid chamber 11 at a bearing cylinder 8 and liquid is immersed from a sliding clearance between the valve shaft 6 and the bearing cylinder 8 and filled in the liquid chamber 11. When the liquid in the main body 1 of a container is discharged from a supplying and discharging port 4 at a speed more than 25m/sec, the poppet valve 5 is rapidly closed. However, the liquid filled in the liquid chamber 11 is compressed by the large diameter upper part (c) of the fast descending valve shaft 6, so that the liquid is compressed to increase the pressure and to resist against the descending of the valve shaft 6 and the opened valve condition is kept. However, when the slow discharging of the liquid is kept, the liquid in the liquid chamber 11 is discharged from the sliding clearance between the valve shaft 6 and the bearing cylinder 8 to close the poppet valve 5.

    Abstract translation: 目的：为了防止通过其中液体填充在轴承圆筒中的液体室中的方法由动态压力快速关闭提升阀。 构成：当提升阀5打开时，阀轴6的大直径上部（c）位于轴承缸8的液体室11的上方，液体从阀轴6和阀轴6之间的滑动间隙浸没 轴承缸8并填充在液体室11中。当容器主体1中的液体以大于25m / sec的速度从供给排出口4排出时，提升阀5快速关闭。 然而，填充在液体室11中的液体被快速下降阀轴6的大直径上部（c）压缩，使得液体被压缩以增加压力并抵抗阀轴6的下降 并保持打开的阀门状态。 然而，当保持液体缓慢排出时，液体室11中的液体从阀轴6和轴承缸8之间的滑动间隙排出，以关闭提升阀5。
