Claims (9)
1. En metallpakning (300), omfattende en sirkelformet pakningsring (304) som danner en gjennomgående boring (310) som er konfigurert til å motta i det minste en del av en a stamme (200), og en sirkelformet pakningsleppe (303) anbrakt eksternt i forhold til nevnte pakningsring; en stamme-inngripende region (305) som er anbrakt omkretsmessig på pakningsringen, og nevnte stamme-inngripende region (305) omfatter et parti (305) med en paknings-coating (307) av et hardt materiale, så som et metall eller et keram med høy hardhet, karakterisert ved at pakningsringen (304) og pakningsleppen (303) strekker seg i den hovedsakelig samme retningen langs en pakningsakse (Y-Y), og pakningsleppen (303) omfatter en coating (309) av et smørende og tettende materiale, hvorved sammenstillingsprosedyre og tetningsegenskaper forbedres.
2. Metallpakningen som angitt i krav 1, der paknings-coatingen (307) omfatter wolframkarbid.
3. Metallpakningen som angitt i kravene 1-2, der coatingen (309) omfatter et lag av sølvbelegg.
4. Metallpakningen som angitt i kravene 1-3, der pakningsringen (304) og pakningsleppen (303) strekker seg i hovedsakelig samme retning langs en pakningsakse (Y-Y), og danner et U-formet profil på pakningen.
5. Metallpakningen som angitt i kravene 1-4, videre omfattende en andre sirkelformet pakningsleppepakning (306) som strekker seg i en hovedsakelig motsatt aksialretning i forhold til pakningsringens (304) og pakningsleppens (303).
6. En metall-mot-metall ventilpakningssystem, karakterisert ved
- metallpakningen som angitt i et hvilket som helst av kravene 1-5, og
- en stamme (200; 200’; 200”) konfigurert for å operating en obdurator (106; 406) i en ventilstrømspassasje (101a; 401a); der nevnte stamme videre omfatter i det minste en stamme-omkretsmessig region (206; 206’a, 206’b; 206”) med en stamme-coating (207) av et materiale som tilsvarer materialet i paknings-coatingen (307).
7. Pakningssystemet som angitt i krav 6, der stamme-coating (207) strekker seg mellom aksialt (Y-Y) med mellomrom anbrakte endepunkter (C1, C2) på stammen, og der et første coatet parti (Ca) i regionen har en første stammediameter (d1) som er større enn en stammediameter (d2) utenfor et andre coatet parti (Cb).
8. Pakningssystemet som angitt i krav 6 eller krav 7, der det andre coatede partiet (Cb) er avfaset utover med en avfasingsvinkel (α) for å danne et inngangsparti for stammepakningen når pakningen er aktivert.
9. Pakningssystemet som angitt i et hvilket som helst av kravene 6-8, der pakningscoatingen (307) og stamme-coatingen (207) er konfigurert to å ligge an og danne et tettende grensesnitt når stammen og pakningen er installert og aktivert.
