The invention relates to a valve arrangement for a mobile working machine (1) having a hydraulic load (47, 50), comprising at least one reversing valve (30, 31, 55, 64), which is connected to a pressure line (P1, P2, 56, 65) and a working line (A1, A2, 52, 54) of the hydraulic load (47, 50) and which comprises a hydraulic control line (C, 58, 63), which is designed to control the pressure line (P1, P2, 56, 65) and the working line (A1, A2, 52, 54) of the hydraulic load (47, 50). Transferring the at least one reversing valve (30, 31, 55, 64) into a first position; a pilot valve (32, 59), which is connected to the hydraulic control line (C, 58, 63); a pressure supply line (Pa, 66); and a pressure relief line (T, 62), the pilot valve (32, 59) being designed to alternately connect the hydraulic control line (C, 58, 63) to the pressure supply line (Pa, 66) and the pressure relief line (T, 62).

    本发明涉及一种用于具有液压负载(47、50)的移动式作业机械(1)的阀装置,所述阀装置具有:至少一个换向阀(30、31、55、64),所述换向阀与液压负载(47、50)的压力管路(P1、P2、56、65)和工作管路(A1、A2、52、54)连接,并且所述换向阀包括液压控制管路(C、58、63),所述液压控制管路设计成用于,使所述至少一个换向阀(30、31、55、64)转换到第一位置;先导阀(32、59),所述先导阀与所述液压控制管路(C、58、63)连接;供压管路(Pa、66);以及泄压管路(T、62),其中,所述先导阀(32、59)设计成用于,使所述液压控制管路(C、58、63)交替地与供压管路(Pa、66)和泄压管路(T、62)连接。
