Abstract
The invention describes a bypass valve () that can be used as a divert air valve. Bypass valves () that work in the closed or opened position in a force-balanced or pressure-balanced manner are known. During the opening of the bypass valve (), a lower pressure is produced in a gap () between a valve closing body () and a valve seat (), which pressure destroys the force balance and thus loads a movable valve unit () in the closing direction. In order to prevent this, according to the invention pressure equalization openings () are embodied or arranged with respect to the gap () in such a way that a reduced pressure is introduced into the chambers () in the interior of the valve, so that the closing-operative force is distinctly reduced. By these means, the opening times of such a bypass valve can be distinctly reduced.
