Description

'Miu- 459 203 10 Ríngarna 5, 6 bildar tillsammans en mekanisk tätning mellan' pumpkammaren och anordningens utsida. Huset 1 täcks av en täckplatta 13. Ett rum 7 beläget mellan glidlagret 4 och den mekaniska tätningen 5,6 matas med smörjmedel för glidlagret medelst en pump 14 genom en kanal 17. Smörjmedel flyter från runnæt 7 genom och genom en kanal 18 och en strypning 16 till en tank 15 variabla strypningen 16 används för att justera trycknivä 7. Detta tryck måste vara högre än gastrycket på andra si mekaniska tätningen 5,6 för att säkerställa att ingen ga från pumpkammaren. Axeltätningen innefattar således en me tätning 5,6 och en labyrinttätníng som består av ett gli lagret 4 . Den n i rummet dan den s läcker ut kanisk dlager 4.

Claims (1)

1. 3 459 205 Patentkrav: Axeltätning för en gaspumpningsanordning, varvid gaspumpningsanordningen innefattar ett hus (1) som definierar en pumpkammare i vilken ett pumpelement (2) är roterbart för att pumpa gas och pumpelementet innefattar en avtätad axelände (3), vars tätning består av två på avstånd anordnade tàtande element vilka mellan sig bildar ett rum i vilket år avsett att inmatas ett tryckrnedium med ett tryck som år högre än gastrycket i npumpkammaren, k ä n n e t e c k n a d d. ä r a-'v att det närmast pumpkanxmaren liggande tätande elementet utgöres av en mekanisk tätning (5,6) och ett axeländen uppbarande glidlager (4) avsett att verka även som en labyrinttátning utgör det andra tàtande elementet, varvid som tryckmedíum utnyttjas smörjmedlet för glidlagret (4).
