The windows (4,5) with an inserted distance element (9) are pressed to one another by two pressure rings (10,11) screwed to the metal housing (2). Each pressure ring has a pressure surface (19,22) which together with the circumferential surface (20,23) of the respective window and an opposing surface of the metal housing forms an annular groove for a sealing ring (21,24). |
