ABSTRACT:
A hydraulic balancing apparatus for a hydraulic machine including means communicating an outer runner crown chamber with a runner band chamber. The communicating means has opposed ends opening in the chambers at the substantially identical radial distance which is determined such that the axial thrust applied to a runner by pressure water in sections of the outer runner crown chamber and of the runner band chamber inside of the opposed ends becomes substantially equal to the axial thrust applied to the runner by pressure water in the remaining sections of the chambers outside of the opposed ends.
