    摘要： A pressure compensator, particularly for oleodynamic applications, comprising two cylinders: a compensator cylinder in which is slidingly engaged a first piston comprising a first piston rod, and a reducing cylinder, in which is slidingly engaged a second piston comprising a second piston rod axially connected to the first piston rod; said compensator cylinder being coupled to a main oleodynamic cylinder; said compensator cylinder having a size so designed as to provide the same area ratio as that of the main cylinder, thereby to a set position of said main cylinder piston corresponding a precise position of the first piston of the compensator cylinder; said reducing cylinder comprising at least a low-pressure chamber coupled to a pressure gauge; a displacement of the reducing cylinder piston rod either increases or decreases a pressure in said low-pressure chamber, proportionately to a working pressure in the main cylinder.

    摘要翻译： 一种压力补偿器，特别是用于油动力应用的压力补偿器，包括两个气缸：补偿器气缸（2），其中滑动地接合包括第一活塞杆的第一活塞（21）和减速缸（3），滑动地接合 第二活塞（31）包括轴向连接到所述第一活塞杆的第二活塞杆; 所述补偿器缸联接到主油压缸; 所述补偿器缸的尺寸被设计成提供与主缸相同的面积比，从而到达与所述补偿器缸的第一活塞的精确位置相对应的所述主缸活塞的设定位置; 所述减压缸包括至少一个连接到压力计的低压室（32） 减压缸活塞杆的位移或者与主缸中的工作压力成比例地增加或者减小所述低压室中的压力。
