Abstract (en)
[origin: WO0129426A1] The invention relates to a method for the improved cooling of a flow regime in radial slits formed between rotors and stators of turbomachines. The invention also relates to a simple, cheap and robust device for implementing said method. According to the invention, said advantages are achieved by using water as a cooling fluid (29) for the stator component (20) which is positioned adjacent to the radial slit (24). At least one recess (26) is either formed on the inside of the radial slit (24) positioned adjacent to said stator component (20) or at least one cavity (38) is located at the stator component (20). Said recess (26) or cavity (38) is connected to a feed line (27) and to an outlet line (28) for the cooling fluid (29).
