FILLING DEVICE FOR FILLING A FLUID RESERVOIR, AND DEVICE FOR COUPLING THE FILLING DEVICE TO A FILLING DUCT OF THE FLUID RESERVOIR

摘要

The invention relates to a device (30) for coupling a filling device (10) to a filling duct (16) of a fluid reservoir (12), comprising fixing means (40) for releasably fixing the filling device (10) in relation to the fluid reservoir (12), sealing means (36) for sealing the filling duct (16) with respect to the surroundings, and linearly movable actuating means (42), by way of the advancing of which the fixing means (40) can be brought into engagement with a generally cylindrical wall (20) which surrounds the filling duct (16). In order to make fixing possible on walls (20) with somewhat different dimensions, profiles or tolerances, it is proposed according to the invention that the fixing means (40) comprise, according to the invention, an elastically deformable single-piece clamping ring (14) which is provided in the circumferential direction thereof with an interruption (46), and that the actuating means (42) press the clamping ring (44) against an abutment (50) during the advancing, as a result of which the clamping ring (44) is deformed elastically and comes into engagement with the wall (20) with a change in the diameter of said clamping ring (44).
