Abstract
The invention relates to a device for cooling at least one component by hydraulic fluid from a hydraulic circuit. The hydraulic circuit includes a hydraulic pump, at least one user of hydraulic energy, and a reservoir. The component is connected into the hydraulic circuit between a heat exchanger and the intake side of the pump. The component is connected into a suction line that connects the reservoir with the pump. Between the component and the pump there is a control valve connected on the output side to a bypass suction line connected with the reservoir. In a first position of the control valve, the suction line is closed and the bypass suction line is open. In a second position of the control valve, the suction line is at least partly open. The heat exchanger can be connected into the suction line or into the return line.
