摘要： The invention relates to a hydraulic machine, in particular to a hydraulic motor with two working lines, from one of which a high pressure line and from the other one a low pressure line is branched off. An electronic control unit and a servo displacement unit are provided to control the displacement of the displacement volume of a drive mechanism of the hydraulic machine, wherein the displacement volume can be determinated by the displacement of a servo piston within the servo displacement unit. For this, the servo piston can be loaded at least on one side via a servo pressure line with hydraulic fluid under servo pressure, wherein the servo pressure level can be adjusted by a control spool arranged moveable within a control valve. For this, hydraulic fluid from the low pressure line or, perhaps, from the high pressure line is guidable via the control valve to the servo pressure line if a suitable control signal is available at a switching valve.

摘要： Hydraulic motor for driving a work equipment comprising a hydraulic drive mechanism with a high pressure side and a low pressure side. On the low pressure side a first throttle orifice and a second throttle orifice within a first bypass line bypassing the first throttle orifice are arranged, whereby at least the throttle orifice opening of the second throttle orifice is adjustable.

摘要翻译： 本发明涉及一种液压机，特别涉及具有两条工作线的液压马达，其中一条高压线路和另一条低压线路分支。 提供电子控制单元和伺服位移单元以控制液压机械的驱动机构的排量的位移，其中可以通过伺服位移单元内的伺服活塞的位移来确定排量。 为此，伺服活塞可以通过伺服压力线至少在一侧通过伺服压力下的液压流体加载，其中伺服压力水平可以通过控制阀调节，控制阀可以在控制阀内移动。 为此，如果在切换阀处有合适的控制信号，则来自低压管路的液压流体或者可能来自高压管路的液压流体可通过控制阀向伺服压力管线引导。
