Abstract
A turbo-compressor having a housing and at least one rotor shaft pivotably supported in the housing, with a free shaft end and with a rotor connected with the other end of the rotor shaft. The free end of the rotor shaft facing away from the rotor projects into a pressure chamber connected with the housing, and is acted upon by a pressurized fluid whose force of pressure compensates for the force of the axial thrust acting on the rotor. Thus, the starting friction of the compressor is lower and drive motors of lower output target can be utilized.
Claims7
A turbo-compressor comprising
- a housing (1);
- at:
- least one rotor shaft (4) pivotably supported in the housing and having a free shaft end;
- a rotor (6) connected to the other end of said rotor shaft (4);
- and
- a pressure chamber (8) connected to said housing (1) for covering the free shaft end and for containing a pressurized fluid, the free shaft end being acted upon by the pressurized fluid, whose force of pressure compensates the force of the axial thrust acting on said rotor (6).
