Abstract
A rotor shaft has: an inlet flow passage through which gas inside a gas compression flow passage flows into an outer cavity of a downstream-side cavity group; a radial flow passage that provides communication between the outer cavity and an axial communication cavity of the downstream-side cavity group; an axial flow passage that provides communication between the axial communication cavity of the downstream-side cavity group and the axial communication cavity of an upstream-side cavity group; another radial flow passage that provides communication between the axial communication cavity and the outer cavity of the upstream-side cavity group; and an outlet flow passage through which the gas inside the outer cavity of the upstream-side cavity group flows out into the gas compression flow passage.
