液压阀安排
摘要：
在此提供了一种液压阀安排(1)，该液压阀安排包括具有一个高压端口(2)和一个低压端口(4)的供应端口安排、具有两个工作端口(6，7)的工作端口安排、被安排在所述高压端口(2)与所述工作端口安排(6，7)之间的第一阀门(13)、被安排在所述低压端口(4)与所述工作端口安排(6，7)之间的第二阀门(14)、用于控制所述第一阀门(13)和所述第二阀门(14)的一个控制器(19)、以及再生流路，所述控制器(19)具有用于接收一个操作者输入装置的信号的一个输入连接件(20)，该再生流路能够通过所述第一阀门(13)和所述第二阀门(14)中的至少一个来建立。这样一种液压阀安排的功能应当得以加强。为此，当所述工作端口安排(6，7)处的进给压力超过一个预定压力水平时，所述控制器(19)使所述再生流路中断。
摘要（英）：

A hydraulic valve arrangement (1) is provided comprising comprising a supply port arrangement having a high pressure port (2) and a low pressure port (4), a working port arrangement having two working ports (6, 7), a first valve (13) arranged between said high pressure port (2) and said working port arrangement (6, 7), a second valve (14) arranged between said low pressure port (4) and said working port arrangement (6, 7), a controller (19) for controlling said first valve (13) and said second valve (14), said controller (19) having an input connection (20) for receiving a signal of an operator input device, and a regenerative flow path which can be established by means of at least one of said first valve (13) and said second valve (14). The function of such a hydraulic valve arrangement should be enhanced. To this end said controller (19) said controller interrupts said regenerative flow path when a feed pressure at said working port arrangement (6, 7) exceeds a predermined pressure level.
