Abstract
A guide vane for a turbomachine having an outer platform, a blade airfoil protruding from the outer platform, extending in a longitudinal direction and defining a cavity in its interior, an inner platform arranged opposite the outer platform and connected to the blade airfoil, and a connecting tube which passes through the cavity of the blade airfoil in the longitudinal direction. The first free end of the tube is inserted into a through-opening formed in the inner platform and materially bonded to the inner platform, and the second free end of the tube is arranged in a cooling fluid inlet opening formed on the outer platform, away from the edge thereof, and projecting outward from the outer platform. At least one guide is attached to the outer platform and designed to guide the connecting tube in the longitudinal direction in the event of a thermal change in length.
