PROBLEM TO BE SOLVED: To provide a hydraulic machinery capable of executing a stable phase modification operation by properly controlling a thickness and a temperature of a water curtain.SOLUTION: The hydraulic machinery of an embodiment includes a stay vane disposed at an inner peripheral side of a casing in which water flows, a guide vane disposed at an inner peripheral side of the stay vane, and a cylinder gate disposed between the stay vane and the guide vane. Further the machinery includes an upper cover disposed at an upper side of the guide vane, and a lower cover disposed at a lower side of the guide vane. Furthermore the upper cover, the lower cover or the cylinder gate has an opening portion to inject the water to a flow channel between th cylinder gate and the guide vane. The opening portion is formed on a position between the cylinder gate and the guide vane, of the upper cover or the lower cover, or a position penetrating through an inner periphery and an outer periphery of the cylinder gate. |
