Abstract: The invention describes a bypass valve (1) that can be used as a divert air valve. Bypass valves (1) 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 (1), a lower pressure is produced in a gap (25) between a valve closing body (3) and a valve seat (20), which pressure destroys the force balance and thus loads a movable valve unit (2) in the closing direction. In order to prevent this, according to the invention pressure equalization openings (24) are embodied or arranged with respect to the gap (25) in such a way that a reduced pressure is introduced into the chambers (7, 8) 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.

Abstract: An actuating device for actuators, such as switching, throttle or swirl flaps, in internal combustion engines for motor vehicles comprises a shaft connected with an actuating motor. The shaft is connected with an actuator, such as a switching flap or the like. In a predetermined position relative to the shaft two pin-type magnets are arranged and preferably connected with a partly toothed gearwheel. When the shaft is rotated, the pin-type magnets move relative to a preferably fixed magnetic field sensor. The magnetic field sensor is a linear Hall sensor. Provision of a linear Hall sensor allows three different shaft positions to be determined. The positions are the two shaft positions defined by the pin-type magnets in which the magnets are arranged opposite the Hall sensor, and a position in which the location of the pin-type magnets does not allow the Hall sensor to detect a magnetic field. In the latter position the linear Hall sensor has a defined bridge voltage.

The control pressure chamber is selectively connected to one of the atmospheric-pressure connector and the underpressure connector to generate a mixed pressure in the control pressure chamber dependent on a position of the plunger-type armature. The position of the plunger-type armature is dependant on the electromagnetic force and on a pneumatic force acting on the membrane.
