    Abstract: The invention relates to a valve device (200) comprising at least one tank pressure port (218), a first pressure port (212), a second pressure port (214), and a pressure shut-off valve (224), which is switched between the individual ports (212, 214, 218), and which has at least two valve components (226, 228). Upon reaching a predefinable pressure cut-off value, the first pressure port (212) can be connected to the tank pressure port (218) by means of the first valve component (226). In the event of the fluid pressure being higher at the second pressure port (214) than at the first pressure port (212), the second pressure port (214) can be separated from the first pressure port (212) by means of the second valve component (228). The invention is characterized in that both valve components (226, 228) are combined to form a tradable structural unit, and in that for this purpose, both valve components (226, 228) are integrated in a common valve housing (230), preferably making direct contact. The invention further relates to a hydraulic system having such a valve device.

    Abstract translation: 本发明涉及一种阀装置(200),其包括至少一个罐压力端口(218),第一压力端口(212),第二压力端口(214)和压力截止阀(224),其是 在各个端口(212,214,218)之间切换,并且具有至少两个阀部件(226,228)。 达到可预定的压力截止值后,第一压力口(212)可通过第一阀组件(226)与罐压力端口(218)连接。 在第二压力端口(214)处的流体压力高于第一压力端口(212)的情况下,第二压力端口(214)可以通过第二压力端口(212)与第一压力端口 阀组件(228)。 本发明的特征在于两个阀组件(226,228)组合以形成可交易的结构单元,并且为此,两个阀组件(226,228)都集成在公共阀壳体(230)中,优选地 直接联系。 本发明还涉及具有这种阀装置的液压系统。
