Abstract: A control valve apparatus includes a second-working-actuator acceleration control valve connected to a first working control valve in parallel. The second-working-actuator acceleration control valve includes pilot chambers receiving a pilot pressure for switching first and second working control valves and a flow channel that guides a pressure fluid of a first pump port to an entrance port side of the second working control valve. The second-working-actuator acceleration control valve is switchable between a first priority position in which a pressure fluid is guided to the first working control valve with a higher priority than the second working control valve and a second priority position in which a pressure fluid is guided to the second working control valve with a higher priority than the first working control valve.

Abstract translation: 控制阀装置包括并联连接到第一工作控制阀的第二工作致动器加速度控制阀。 第二加工执行器加速控制阀包括接收用于切换第一和第二工作控制阀的先导压力的引导室和将第一泵口的压力流体引导到第二工作控制阀的入口侧的流路。 第二工作执行器加速控制阀可以在其中将压力流体以比第二工作控制阀更高的优先级被引导到第一工作控制阀的第一优先位置和压力​​流体为第二优先位置之间切换 被引导到比第一工作控制阀更高优先级的第二工作控制阀。
