可再充装的海底生力装置和方法
摘要：
本发明涉及一种可再充装的海底生力装置和方法。用于恢复连接到海底压力控制装置上的低压接收器中的压力的方法和装置。该装置包括：构造成具有被第一活塞隔开的第一室和第二室的低压接收器；构造成具有被活塞组件隔开的第三室和第四室的恢复接收器，活塞组件包括具有沿着活塞组件的移动方向延伸的第一延伸元件和第二延伸元件的第二活塞。第三室具有构造成允许液压液体进入第三室的入口，以及构造成允许液压液体离开第三室的出口，且第四室具有构造成允许液压液体进入第四室的入口和构造成允许液压液体离开第四室的出口。
摘要（英）：

The present invention relates to a rechargeable subsea force generating device and method to be used for resetting a pressure in a low pressure recipient connected to a subsea pressure control device. The device includes the low pressure recipient configured to have first and second chambers separated by a first piston; a reset recipient configured to have third and fourth chambers separated by a piston assembly, and the piston assembly includes a second piston having first and second extension elements that extend along a direction of movement of the piston assembly. The third chamber has an inlet configured to allow the hydraulic liquid to enter the third chamber and an outlet configured to allow the hydraulic liquid to exit the third chamber, and the fourth chamber has an inlet configured to allow the hydraulic liquid to enter the fourth chamber and an outlet configured to allow the hydraulic liquid to exit the fourth chamber.
