摘要： A hydraulic control device according to the invention is of load-sensing design and serves to actuate a first hydraulic load and a second hydraulic load. Also provided are a first control valve for actuating the first hydraulic load and a second control valve for actuating the second hydraulic load. A first load signal can be measured on the basis of a load pressure with which the first hydraulic load is acted on, and a second load signal can be measured on the basis of a load pressure with which the second hydraulic load is acted on. Pressure medium from a pressure medium source can be supplied in parallel to the first control valve and to the second control valve. A load signal path can, in order to actuate an adjusting element which is assigned to the pressure medium source, be acted on with a highest presently measured load signal. A limiting device allows the second load signal to be limited to a predefined signal limit value. A switching means can be actuated by means of the second load signal such that, at the latest when the second load signal reaches the signal limit value, the signal conveyed on the load signal path is limited by the limiting device.
摘要翻译：根据本发明的液压控制装置具有负载感应设计并用于致动第一液压负载和第二液压负载。还提供了用于致动第一液压负载的第一控制阀和用于致动第二液压负载的第二控制阀。第一负载信号可以基于第一液压负载作用于其上的负载压力来测量，并且第二负载信号可以基于第二液压负载作用于其上的负载压力来测量。来自压力介质源的压力介质可以与第一控制阀和第二控制阀并联供应。负载信号路径可以为了启动分配给压力介质源的调节元件而以当前测量的最高负载信号加载。限制装置允许第二负载信号被限制到预定义的信号限制值。借助于第二负载信号可以启动开关装置，使得最迟当第二负载信号达到信号极限值时，在负载信号路径上传送的信号受到限制装置的限制。

摘要： The invention relates to a hydraulic control device for a priority, first hydraulic consumer and a subordinate, second hydraulic consumer, pressure medium being deliverable to the first or the second consumer via a first or a second metering diaphragm. A pressure scale which allows a constant pressure difference to be adjusted above the first metering diaphragm is mounted upstream from the first metering diaphragm. For this purpose, said pressure scale is provided with a valve piston encompassing a first control edge, by means of which a first flow area between a feeding duct and the first metering diaphragm can be controlled. A second pressure scale which can be impinged upon in the closing direction by control pressure prevailing in a control chamber while being impinged upon in the opening direction by the pressure applied downstream from the second measuring diaphragm is mounted downstream from the second measuring diaphragm. A variable delivered amount of pressure medium source can be controlled in accordance with the maximum load pressure of the actuated hydraulic consumer such that the pressure in the feeding duct exceeds the maximum load pressure by a certain pressure difference. A load signaling line can be impinged upon by the load pressure of the second hydraulic consumer or a pressure that is derived therefrom while being connected to the control chamber of the second pressure scale and a control member of the pressure medium source. A second control edge which allows a second flow area to be controlled between the feeding duct and the load signaling line is provided on the valve piston of the first pressure scale.

摘要： Disclosed is a valve arrangement for triggering consumers (4) in a manner that is independent from the load pressure, comprising a main valve (10) which is provided with a directional part and a metering cover part. The valve arrangement comprises a check valve (18) for sealing in a leakage-free manner a working pipe which leads to the consumer. Said check valve (18) is provided with a pilot valve (20) via which a pressure chamber of the check valve (18), which acts in the closing direction thereof, can be relieved towards a tank or a low-pressure source. The pilot valve (20) is controlled by a main slider (12) of the main valve (10).

摘要： A hydraulic control arrangement is disclosed, for the load-independent control of a user with a continuously adjustable distribution valve (4) having a pressure compensator (2) down the line. According to the invention, the pressure compensator has a single-sided damping such that the movement in the opening direction is damped and the movement in the closing direction is essentially undamped. Furthermore, a control arrangement is disclosed in which a load holding function is integrated in the pressure compensator.
