Abstract
A hydraulic system for a working machine includes a hydraulic pump, a first hydraulic actuator, a second hydraulic actuator, a first control valve to control the first hydraulic actuator, a second control valve to control the second hydraulic actuator, and a discharge fluid tube in which the operation fluid flows. The discharge fluid tube is connected to the first control valve. The hydraulic system includes a first fluid tube in which a return fluid flows toward the second control valve. The first fluid tube couples the first control valve to the second control valve. The hydraulic system includes a second fluid tube coupling the first fluid tube and the discharge fluid tube, a first throttle disposed on the first fluid tube, and a second throttle disposed on the second fluid tube, the second throttle having an opening area smaller than an opening area of the first throttle.
