Abstract
Provided is a work machine including a flow control valve serving as a flow control mechanism that controls a flow rate of pressurized fluid from a hydraulic pump to a hydraulic actuator via a first control valve. A controller of the work machine, when the pressurized fluid is supplied to the hydraulic actuator from only an accumulator, drives a second control valve such that a meter-in side of the hydraulic actuator and the accumulator are connected to each other, drives the first control valve such that a meter-out side of the hydraulic actuator and a tank are connected to each other, and drives the flow rate control mechanism such that a flow of the pressurized fluid from the hydraulic pump to the hydraulic actuator via the first control valve is interrupted.
