Abstract

Przedmiotem wynalazku jest gazowa maszyna przepływowa (4), która zawiera część sprężarkową, część turbinową połączoną roboczo z częścią sprężarkową (6) i zespół komory spalania (12), połączony przepływowo z każdą z części sprężarkowej i części turbinowej (8). Obudowa turbiny zawiera korpus o powierzchni zewnętrznej i powierzchni wewnętrznej. System regulacji luzu zawiera liczne połączone przepływowo kanały płynu, przechodzące przez obudowę turbiny. Do licznych połączonych przepływowo kanałów płynu należy pierwszy kanał płynu, skonfigurowany do kierowania strumienia płynu w pierwszym kierunku osiowym, obwodowy kanał płynu skonfigurowany do kierowania strumienia płynu w kierunku obwodowym i drugi kanał płynu, skonfigurowany do kierowania strumienia płynu w drugim kierunku osiowym, zasadniczo przeciwnym do pierwszego kierunku osiowego. Pierwszy kanał płynu zawiera pierwszy wylot, przechodzący przez powierzchnię wewnętrzną, a drugi kanał płynu zawiera drugi wylot, przechodzący przez powierzchnię wewnętrzną.
