Abstract: A hydraulic hinge for the lid of a food serving vessel in a buffet restaurant includes a hinge block, a shaft pivotally mounted to the hinge block, an annular hydraulic chamber within the hinge block and at least partially surrounding the shaft, and a one-way valve having an inlet port and an outlet port each communicating with the hydraulic chamber and allowing hydraulic fluid to flow from the inlet port to the outlet port but not vice versa. The hinge further includes a rotary piston extending from the shaft across the annular hydraulic chamber and adapted to pivot with the shaft between the inlet and outlet ports and comprising a flow restrictor allowing hydraulic fluid to flow relatively slowly therethrough. This prevents the lid from dropping after patrons release the lid.
Abstract translation: 在自助餐厅中用于食品供应容器的盖的液压铰链包括铰链块，枢转地安装到铰链块的轴，铰链块内的环形液压室，并且至少部分地围绕轴，以及单向 阀具有入口端口和出口端口，每个端口和出口与液压室连通并且允许液压流体从入口端口流到出口端口，但是反之亦然。 所述铰链还包括旋转活塞，所述旋转活塞从所述轴延伸通过所述环形液压室，并且适于在所述入口和出口之间与所述轴一起枢转，并且包括允许液压流体相对缓慢地流过的限流器。 这样可以防止盖子释放盖子后盖子掉落。
