ABSTRACT:
A telescopic filling adapter of the type adapted to be mounted on the filling valve of a bottle filling machine is comprised of a mounting element adapted to be sealingly engaged with the filling valve. A centering element is provided with an annular seal for engaging a bottle opening and is mounted for telescopic sliding movement relative to the mounting element. One of the elements defines an annular telescopic chamber for slidably receiving the other element with sufficient clearance to permit the passage of fluid into the telescopic chamber during a bottle filling operation. A sealing ring is provided between the mounting element and the centering element so that the telescopic chamber may be pressurized when the mounting element is sealingly engaged with the filler valve and the centering element is sealingly engaged with a bottle. Suitable springs are provided for biasing the centering element into pressure engagement with the bottle.
