ABSTRACT:
Device for compensating pressure differences between the inside and the outside of an insulating glass frame, including a closed cylindrical hollow body which is arranged, so that its axis is not horizontal, between the inside and the outside of an insulating glass frame. A ball is movable within the body and has such a diameter as to be in contact with the wall, so as to fully separate the inside into two regions. At least one first hole for connection to the outside/inside is located in a suitable wall portion affected by the passage of the ball, and at least one second hole for connection to the inside/outside is located on the bottom.
