Patent ID: 8578968

Claim:
An electric switching valve for controlling a pneumatic actuator element, the electric switching valve comprising: an integral housing comprising a vacuum connection channel comprising a first valve seat, a ventilation connection channel comprising a second valve seat, and a consumer connection channel; an electromagnetic drive arranged in the housing, the electromagnetic drive being configured so that a magnetic armature is translationally movable in a passage channel arranged between the ventilation connection channel and the vacuum connection channel to form a valve closure body for each of the vacuum connection channel and the ventilation connection channel; and a cross-sectional constriction device selected from at least one of a nozzle and an aperture, the cross-sectional constriction being disposed in the ventilation connection channel, wherein, the vacuum connection channel, the ventilation connection channel, the electromagnetic drive, the magnetic armature, the passage channel and the valve closure body are each aligned on a same axis, wherein, the consumer connection channel is arranged perpendicular to the same axis and is arranged directly next to the vacuum connection channel, and wherein, when the electric switching valve is switched into a deenergized state, the ventilation connection channel is in an open position so that air flowing therethrough is throttled by the cross-sectional constriction device.
