Abstract
An electric switching valve for controlling a pneumatic actuator element includes a housing with a ventilation connection channel, a vacuum connection channel and a consumer connection channel. The vacuum connection channel comprises a first valve seat and the ventilation connection channel comprises a second valve seat. An electromagnetic drive is arranged in the housing. The electromagnetic drive is configured so that a magnetic armature is translationally movable in a passage channel to form a valve closure body for each of the vacuum connection channel and the ventilation connection channel. A cross-sectional constriction device is disposed in the ventilation connection channel.
