A lateral channel compressor having an annular flywheel housing (1) with air inlet stub (3) and air outlet stub (4). Attachments such as mufflers, filters, or safety valves are connected to stubs. A compact design and a lower manufacturing cost is achieved when the attachments are made in the form of a kit preferably having equal-length elements (I,II,III,IV) connectable directly to one another in the axial direction. The elements preferably have tubular main housings (11, 12) flush with one another. The filter and safety valve attachments (II, III, IV) each have a housing stub (13) projecting laterally from main housing (12) for mounting of filter elements and valve components.

Compressor with attachments mounted on stubs of a housing of the

A turbine including a radial compressor having radial blades, with the compressor supplying side channel compressors arranged at its circumference and having chamber blades. To increase the efficiency, the chamber blades and the radial blades are curved in opposite directions, with the chamber blades and radial blades having a curvature transition point at their transition area, and the blades, in the transition area, are inclined by an identical angle of less than 30.degree. and, for example, 15.degree. relative to a circumferential tangent in the transition area.

Turbine for gas compression

A compact flowing gas laser, particularly a CO.sub.2 gas laser, wherein the path or paths between the outlet or outlets and the inlet or inlets of one or more optical resonators contain a turbine whose impeller or impellers are driven by heated gas and which drives the impeller or impellers of a rotor forming part of a compressor serving to compress the thus cooled and expanded gaseous lasing medium prior to reentry into the resonator or resonators. A first heat exchanger is installed between the turbine and the compressor, and a second heat exchanger is provided downstream of the compressor.
