Abstract
A hydraulic system for a working machine includes a hydraulic actuator configured to be operated by operation fluid, a control valve connected to the hydraulic actuator, and a communication fluid line for fluid communication between the hydraulic actuator and the control valve. The control valve includes a first supply path to guide the operation fluid toward the hydraulic actuator; a regeneration path to guide the operation fluid having been returned to the control valve from the hydraulic actuator, to the first supply path; and a branched path that branches from the regeneration path and supplies operation fluid to outside of the control valve.
