Abstract: A turbomachine inner housing for a radial turbomachine, wherein the turbomachine inner housing includes a partial joint along a longitudinal axis, in particular a rotor longitudinal axis, such that the turbomachine inner housing can be divided into a lower part and an upper part, wherein the turbomachine inner housing is designed for a radial turbomachine with at least two stages, wherein the turbomachine inner housing has a return stage in each case between two stages, wherein the lower part and/or the upper part is designed in one piece so as to span at least two stages at least in sections. In order to improve a turbomachine inner housing of this kind, the lower part and/or the upper part is designed in one piece so as span at least two stages at least in sections.

Abstract: A turbomachine housing, in particular of a radial turbomachine which transfers technical work to a process fluid or from a process fluid, includes: an opening extending along an axis, for the axial feed-through of a shaft extending along said axis; a contact surface extending along a circumferential direction with respect to the axis, for contact with a housing jacket of the turbomachine housing. A flow line provided as an inflow or outflow of the process fluid is designed as an integral part of the cover.
