Zusammenfassung:	In a hydraulic machine, first travel control valve and a first attachment control valve are in fluid communication with a second hydraulic source. A confluence control valve is in fluid communication with a first hydraulic source and, in a confluence position, directs fluid from the first hydraulic source to the first attachment control valve. A first signal line and a first pilot line are connected to the confluence control valve. When the first travel control valve is in a non-neutral position and the first attachment control valve is in a first non-neutral position, first signal pressure is generated in the first signal line to move the confluence control valve to the confluence position. First pilot pressure, when generated in the first pilot line, moves the confluence control valve to the confluence position.
