Abstract: A runner vane of an axial hydraulic machine according to embodiments described herein includes a center-side vane part provided on a radial center side and defined by a center-side camber line, and a boss-side vane part provided at a side edge on a side of a runner boss and defined by a boss-side camber line. As determined by the flow direction of a turbine, a curvature of an upstream side portion of the boss-side camber line is larger than a curvature of an upstream side portion of the center-side camber line. An upstream end of the boss-side vane part is positioned on a side of a rotation direction of a runner in comparison with an upstream end of the center-side vane part when viewed toward a downstream side along a rotation axis line of the runner.

Abstract: A hydraulic machine according to embodiments described herein includes a channel defining member, a plurality of guide vanes, and a runner. The channel defining member defines a channel. Each of the guide vanes can turn about a turning axis. The runner is provided on an inner peripheral side of the guide vanes. The guide vane has a pair of edges facing the channel defining member. A disc member is provided to at least one of the edges of the guide vane. The disc member is buried in the channel defining member and includes a central axis which is the turning axis. The disc member overlaps with at least one of an upstream end of a downstream end of the guide vane when viewed from a direction along the turning axis.
