Seal between the surfaces of two machine units is an inflatable hose within an open groove flush at one surface which can be filled with a pressure medium to bear in a sealed fit against the other surface

摘要

The seal, between at least two facing surfaces (1,2) of neighboring machine units (3,4), has an inflatable sealing hose (5) within a groove (6) at one of the surfaces (1), which is open towards the other surface (2). The hose (5) can be filled with a pressure medium (7) to inflate it, and bear against the facing surface (2) with a sealing action. The outer ends (10,11) of the hose (5) are held in insert units as a sleeve (12,13) in a sealed and clamped elastic fit round the hose ends (10,11). The sleeves (12,13) are fitted into holder openings (14,15) at the first machine unit (3), across the longitudinal line (16) of the groove (6). The relaxed hose (5) and the end sides (17,18) of the hose sleeves (12,13) are flush with the surface (1) of the first machine unit (3).
