Hydraulic system for working machine

Abstract

A hydraulic system for a working machine, includes a hydraulic device to change a flow rate of an operation fluid. The hydraulic device includes a first hydraulic receiver to which the operation fluid is applied, a second hydraulic receiver to which the operation fluid is applied, and a movable portion to be moved by the operation fluid applied to any one of the first hydraulic receiver and the second hydraulic portion. A hydraulic system further includes a differential pressure regulator to supply the operation fluid to the first hydraulic receiver and the second hydraulic receiver, the differential pressure regulator being configured to regulate a differential pressure between a first pressure that is a pressure of the operation fluid applied to the first hydraulic receiver and a second pressure that is a pressure of the operation fluid applied to the second hydraulic receiver.
