Abstract: Compressor arrangement having an axial compressor and a radial compressor which are arranged axially one behind the other on a common driveshaft which can be coupled to a drive and which each have a compression fluid input and a compression fluid output. The axial compressor is provided with first control elements and the radial compressor is provided with second control elements. The first control elements and second control elements are controllable separately so that the axial compressor and the radial compressor are controllable separately.

Abstract: An inlet connection piece for an axial compressor, particularly for a turbocompressor, includes an inlet housing (1) in which is arranged a bearing housing (2) with a bearing (3), particularly a radial and/or axial bearing, for a rotor. The bearing housing (2) is connected to the inlet housing (1) by an inlet strut (4) which is connected to the inlet housing in a front cross section. The center of the bearing (3) is arranged axially in the flow direction of a fluid to be compressed behind the area center of the front cross section by at least 0.1-times, particularly at least 0.15-times, particularly at least 0.2-times, particularly at least 0.25-times, the chord length of the front cross section. In addition or alternatively, a fluid passage (5, 6) is formed in the inlet strut (4), and at least portions of this fluid passage (5, 6) form an acute angle with a normal plane relative to the longitudinal axis of the inlet connection piece.
