摘要： An arrangement (2) for selectively making available hydraulic power in separate hydraulic circuits comprises two displacement machines (4, 6), two free-wheels (8, 10) and a drive unit (12) that is preferably arranged between the displacement machines (4, 6). The free- wheels block in opposite directions and are coupled to the displacement machines. Consequently, the first displacement machine (4) is driven in a first rotating direction of the drive unit (12) while the second displacement machine (6) is only driven in a second, opposite rotating direction of the drive unit. This makes it possible to realize an intermittent operation for selectively making available additional hydraulic power in separate hydraulic subsystems by choosing the rotating direction accordingly. This arrangement can reduce the weight and the complexity of a hydraulic system.
摘要翻译：用于在分开的液压回路中选择性地提供液压动力的装置（2）包括两个排量机器（4,6），两个空转轮（8,10）和驱动单元（12）优选布置在移位机器（4,6）之间。自由轮在相反的方向上阻挡，并连接到位移机器。因此，第一位移机（4）在驱动单元（12）的第一旋转方向上被驱动，而第二位移机（6）仅在驱动单元的相反的第二旋转方向上被驱动。这使得可以通过相应地选择旋转方向来实现间歇操作，以在分离的液压子系统中选择性地提供额外的液压动力。这种安排可以减轻液压系统的重量和复杂性。

摘要： A pressure compensator, particularly for oleodynamic applications, comprising two cylinders: a compensator cylinder (2) in which is slidingly engaged a first piston (21) comprising a first piston rod, and a reducing cylinder (3), in which is slidingly engaged a second piston (31) 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 (32) 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.
