具有密封件的势能存储器
Abstract:
本发明提供了一种势能存储器(100)，其具有液压缸(110)，在液压缸(110)中配置有活塞(120)，用于存储以活塞(120)势能形式的能量，其中活塞(120)相对于地表的位置可改变；势能存储器具有泵，通过泵可将液压流体经由管线泵送到液压缸(110)内从而提升活塞(120)；势能存储器具有发电机，其用于将在活塞(120)下降过程中从液压缸(110)挤出的液压流体(130)的流动能转变成电，其中，在液压缸(110)和活塞(120)之间至少部分地配置有密封件(400、500、600、700、701、800、900、1000)或者密封装置(1200、1300、1400、1500)，其特征在于，密封件(400、500、600、700、701、800、900、1000)或者密封装置(1200、1300、1400、1500)具有至少一个密封段，该密封段具有用于吸收作用力的柔性支撑结构，柔性支撑结构的一侧或两侧涂覆有不渗透流体并对流体通路起密封作用的层或者浸渍有不渗透流体的固化材料。
Abstract(English):

A potential energy store has a hydraulic cylinder in which a piston for storing energy in the form of potential energy of the piston is arranged. A position of the piston relative to the earth's surface can be varied. A pump pumps hydraulic fluid via lines into the hydraulic cylinder such that the piston is raised. A generator converts hydraulic energy of hydraulic fluid, which is displaced out of the hydraulic cylinder as the piston falls, into electricity. A seal arrangement is at least partially arranged between the hydraulic cylinder and the piston. The seal arrangement has a sealing section with a flexible support structure for absorbing the acting forces. The support structure may be coated on one or both sides with a layer which is impervious to fluid and which seals against the passage of fluid or may be impregnated with a solidified material which is impervious to fluid.
