Claims (6)

1. Aerostatisk luft- og/eller gasleje med mindst en stator (1) og mindst en rotor (2), hvor statoren (1) omfatter mindst en åbning (5.1,5.2) og en ringnot (7), hvor åbningen (5.1,5.2) forsyner en lejeflade (14) af det aerostatiske leje (L) og statorens (1) ringnot (7) med trykluft og/eller med trykgas, hvor ringnoten (7) i statoren (1) er periferisk, kendetegnet ved, at ringnoten (7) er anbragt i området af lejefladen (14), hvor en infusionsdel (4) er indført mellem statoren (1) og rotoren (2), hvor lejefladen (14) er anbragt mellem infusionsdelen (4) og rotoren (2) og ringnoten (7) i statoren (1) omfatter en ringindsats (3), hvor ringindsatsen (3) er materialefast forbundet med statoren (1) , hvor den materialefaste forbindelse er en svejsesamling (6, 6.1, 6.2), hvor ringindsatsen (3) omfatter en åbning (10) i form af flere dyser og/eller mikrodyser og/eller i det mindste to slidsudløb, og hvor infusionsdelen (4) omfatter en åbning (13), hvor åbningens (13) position i infusionsdelen (4) stemmer overens med positionen af åbningen (10) i ringindsatsen (3).
2. Aerostatisk luft- og/eller gasleje ifølge krav 1, kendetegnet ved, at åbningen (10) i ringindsatsen (3) modtager en indsats (9).
3. Aerostatisk luft- og/eller gasleje ifølge krav 1, kendetegnet ved, at åbningen (13) i infusionsdelen (4) og/eller indsatsen (9) i ringindsatsen (3) er dannet i form af en dyse (8) .
4. Aerostatisk luft- og/eller gasleje ifølge et af kravene 1 til 3, kendetegnet ved, at åbningen (13) i infusionsdelen (4) og/eller indsatsen (9) og /eller åbningen (10) i ringindsatsen (3) leder trykluft og/eller trykgas ind i lejeoverfladen (14) mellem rotoren (2) og infusionsdelen (4).
5. Aerostatisk luft- og/eller gasleje ifølge et af kravene 1 til 4, kendetegnet ved, at åbningen (5.1,5.2), som skal forsyne det aerostatiske leje (L) med trykluft og/eller med trykgas, er en boring.
6. Aerostatisk leje ifølge et af kravene 1 til 5, kendetegnet ved, at ringnoten (7) kan tilføres trykluft og/eller trykgas via en enkelt adgang, fortrinsvis via åbningen (5.1,5.2).
