摘要： A directional valve for controlling an actuator by means of pressurized medium, the directional valve comprising: a spool (4) fitted to move axially inside the directional valve; a first position of the spool (4), in which the spool tends to be set; and a second position of the spool (4), to which the spool can be moved by a pilot control force. In addition to the functions of a directional valve, the directional valve comprises a metering orifice (7) placed in the pressure port (P) or in the first work port (A) or in the second work port (B) or in the tank port (T), and across which a pressure difference is effective. The spool (4) further comprises a second position, to which the spool can be moved by a pilot control force. When the spool (4) is in at least the second position, the directional valve is fitted to generate a compensating force proportional to said pressure difference, to move the spool (4) to compensate for the flow.
摘要翻译：一种用于通过加压介质控制致动器的方向阀，所述方向阀包括：阀芯（4），其装配成在所述方向阀内方向轴向移动; 卷轴（4）的第一位置，其中卷轴倾向于设定; 以及阀芯（4）的第二位置，所述阀芯可以通过先导控制力移动到所述阀芯的第二位置。除了方向阀的功能之外，方向阀还包括放置在压力端口（P）或第一工作端口（A）或第二工作端口（B）或储罐中的计量孔（7）端口（T），并且压力差有效。阀芯（4）还包括第二位置，阀芯可以通过先导控制力移动到该第二位置。当阀芯（4）处于至少第二位置时，方向阀被安装成产生与所述压力差成比例的补偿力，以使阀芯（4）移动以补偿流量。

摘要： A directional valve for controlling an actuator by means of pressurized medium, comprising at least: a pressure port (P); a work port (A); a tank port (T); a spool (4) moving axially inside the body of the directional valve; a first position of the spool (4), in which the spool tends to be set, and a second position, to which the spool can be moved by a pilot control force and in which the spool opens the flow of pressurized medium from the pressure port (P) to the work port (A). In addition to the directional valve functions, the directional valve further comprises a feedback chamber (8) in which the pressure is fitted to generate a feedback force effective on the spool (4) and opposite to the pilot control force. In its second position, the spool (4) is further fitted to guide the pressure of the work port (A) to the feedback chamber (8), and in the second position of the spool (4), the directional valve generates a feedback force proportional to the pres¬ sure of the work port (A), moving the spool (4) to shut off the flow.
