ABSTRACT:
A blower serves for circulating larger gas volumes, in particular for high-power laser systems operating according to the gas-transportation principle. The blower comprises a radial compressor, having a compressor element extending into a connection duct to blow a gas from a first to a second gas duct. The radial compressor is driven by a vertical shaft which is provided with an axial and radial gas bearing within a gas-tight housing. A gas duct system is provided for supplying lubricating gas to both the axial and the radial gas bearings. The gas duct system is fed by both one of the axial gas bearings and by an external pressure-gas pump. Throttles and adjustable valves are provided at predetermined locations of the gas duct system to establish a predetermined profile of gas pressure in the duct system.
