1. A manifold for deflecting a flow of a medium flowing through the manifold from an inlet side of the manifold to an outlet side of the manifold, the manifold comprising:
the inlet side;
the outlet side, the manifold defining a first flow axis associated with the inlet side of the manifold and a second flow axis associated with the outlet side of the manifold, the first flow axis and the second flow axis being arranged at an angle relative to one another;
a wall at least partially defining and thereby restricting a flow volume of the manifold, the wall including an inside wall section that is curved and an outside wall section that is curved, the inside wall section including a first radius of curvature, the outside wall section including a second radius of curvature that is larger than the first radius of curvature, the inside wall section including a formed-in section which is formed into the flow volume and is drawn in a direction of flow of the medium; and
a diffuser section arranged centrally in the flow volume on the inlet side, the diffuser section being a single component with the wall and being a hub diffuser configured for a turbomachine, the diffuser section being configured such that, during an operation of the manifold, the medium flows around and thus not through the diffuser section, the outside wall section—in a sectional plane perpendicular to a cross-sectional plane and to a longitudinal sectional plane of the manifold—including two indentations which are arranged laterally to the diffuser section and are formed into the flow volume.
