摘要:
The invention relates to a hydraulic valve device (1) including a high pressure connection (P′) and a low pressure connection (T′); at least one motor port connection (A′) that is connectable to a motor port (A) on a hydraulic motor (M), preferably a hydraulic cylinder; a flow control valve (F), which is arranged between the high pressure connection (P′) and the motor port connection (A′) and which includes a flow opening (18) that is adjustable between a fully closed position and a fully open position; and a pressure regulator (R) that is arranged between the high pressure connection (P′) and the flow regulating valve (F), wherein a regulator pressure (PR) that acts at a first connection point (3) between the pressure regulator (R) and the flow regulating valve (F) acts on the pressure regulator (R) via a first control conduit (4) to close the same. A second control conduit (5) including a first restrictor (6), is arranged to convey a load pressure (PL) that acts at the motor port connection (A′) from a second connection point (7) positioned between the flow regulating valve (F) and the motor port connection (A′) via the first restrictor (6) to a third connection point (8) at which a first control pressure (Pc) acts and which third connection point (8) is connected to the pressure regulator (R) to act on the same in the opening direction by means of said first control pressure (Pc), wherein the third connection point (8) is connected to the low pressure connection (T), via an adjustable second restrictor (9).
摘要(中):
本发明涉及一种包括高压连接(P')和低压连接(T')的液压阀装置(1)。 至少一个可连接到液压马达(M)上的马达端口(A)的马达端口连接件(A'),优选为液压缸; 流量控制阀(F),其布置在高压连接(P')和马达端口连接(A')之间,并且包括流动开口(18),其可在完全关闭位置和完全打开 位置; 以及配置在所述高压连接部(P')和所述流量调节阀(F)之间的压力调节器(R),其特征在于,所述调压器压力(PR)作用在所述压力调节器 R)和流量调节阀(F)经由第一控制管道(4)作用在压力调节器(R)上以将其关闭。 包括第一限流器(6)的第二控制管道(5)被布置成传送从位于流量调节阀(2)之间的第二连接点(7)起作用于马达端口连接(A')的负载压力(PL) (F)和所述马达端口连接(A')经由所述第一限制器(6)连接到第三连接点(8),在所述第三连接点处,第一控制压力(Pc)作用在所述第三连接点(8) 调节器(R)通过所述第一控制压力(Pc)在打开方向上相同地工作,其中第三连接点(8)经由可调节的第二限制器(9)连接到低压连接件(T) )。
