Claims (11)

1. Rotacijska mašina koja sadrži: kućište; rotor (720) koji ima aksijalnu površinu; i brtveni sklop za brtvljenje razmaka između aksijalne površine rotora i strane (740) kućišta, gdje brtveni sklop sadrži: prednju brtvu koja ima: vanjski član (711) koji ima (i) aksijalnu kontaktnu površinu (715), aksijalno opterećenu na stranu (740) kućišta, (ii) najmanje jednu drugu površinu (714, 718) za primanje pritiska tekućine i (iii) unutrašnju radijalnu kontaktnu površinu (719) koja je radijalno opterećena na rotor pritiskom tekućine; i član mosta (713) spojen sa vanjskim članom, koji se proteže na radijalnoj udaljenosti prema unutra od vanjskog člana, pri čemu je član mosta konfiguriran da ograniči kretanje prednje brtve radijalno prema van, pri čemu su aksijalna kontaktna površina (715) i najmanje jedna druga površina (714, 718) za primanje pritiska tekućine oblikovane tako da pritisak tekućine izaziva neto silu kojom se aksijalna kontaktna površina (715) potiskuje aksijalno prema strani (740) kućišta i unutrašnja radijalna kontaktna površina (719) vanjskog člana (711) se potiskuje radijalno prema rotoru (720).
2. Rotacijska mašina prema zahtjevu 1, pri čemu prednja brtva dalje sadrži aksijalno napregnutu oprugu (750) postavljenu između člana mosta i svojstva (724) rotora, tako da izaziva aksijalno opterećenje aksijalne kontaktne površine na strani kućišta.
3. Rotacijska mašina prema zahtjevu 2, koja dalje sadrži sekundarnu brtvu (760), postavljenu između aksijalno napregnute opruge i člana mosta, tako da je sekundarna brtva aksijalno napregnuta oprugom i radijalno napregnuta na rotoru pritiskom bilo koje tekućine koja je upuhana preko unutrašnje radijalne kontaktne površine.
4. Rotacijska mašina prema zahtjevu 1, koja dalje sadrži fleksibilnu sekundarnu brtvu (1304), postavljenu radijalno između rotora i prednje brtve.
5. Rotacijska mašina prema zahtjevu 1, pri čemu brtveni sklop dalje uključuje skup opruga (903), spojenih sa prednjom brtvom i rotorom i konfiguriranih da povuku vanjski član radijalno prema osi rotora.

7. Rotacijska mašina prema zahtjevu 6, pri čemu pločasti član uključuje skup otvora (1020) u sebi kako bi omogućio prolaz zraka za hlađenje kroz rotor.
8. Rotacijska mašina prema zahtjevu 1, pri čemu rotor (1201) ima radijalno lice, gdje rotacijska mašina dalje sadrži: rukavac (1202) postavljen po obujmu preko radijalnog lica; pri čemu rukavac ima jezičak (1203) koji se proteže radijalno prema unutra i rotor ima odgovarajući radijalno uvučeni žljeb u koji može primiti taj jezičak.
9. Rotacijska mašina prema zahtjevu 8, koja dalje sadrži: sklop bočne brtve, postavljen na radijalnom licu rotora, gdje sklop bočne brtve ima primarnu brtvu (1403) i kompresibilnu sekundarnu brtvu (1404), gdje je sekundarna brtva u kontaktu sa primarnom brtvom i postavljena u žljebu rotora.
10. Rotacijska mašina prema zahtjevu 8 koja ima periferni kutni isječak za odgovarajuće oblikovanu bočnu brtvu.
11. Rotacijska mašina prema zahtjevu 8, pri čemu rotor rotira u odnosu na kućište da bi uspostavio radnu komoru, gdje rotacijska mašina dalje ima usisni otvor za dopuštanje svježem mediju da uđe u radnu komoru i ispušni otvor za dopuštanje izgaranim plinovima da izađu iz radne komore.
