| description | An object of the present invention is to solve such problems associated with a merging circuit using a pair of spool-type direction switching valves, in that the installation space of a hydraulic valve device increases and the processing that requires accuracy becomes complex. A merging circuit includes a direction switching valve that merges oil discharged from first and second pumps to supply the oil to an actuator; and a controller. The direction switching valve includes a central bypass oil path connected to the discharge oil paths of the first and second pumps, a first parallel supply oil path connected to the discharge oil path of the first pump, and a second parallel supply oil path connected to the discharge oil path of the second pump and connected to a first parallel oil path via a poppet-type flow regulating valve. The poppet-type flow regulating valve regulates the flow rate to a predetermined magnitude according to a signal of the controller. |
