摘要 |
An electropneumatic converter for connection with an exhaust recirculation valve in a motor vehicle. The electropneumatic converter includes a vacuum port and an atmospheric pressure port configured to connect with a valve chamber using a valve device, wherein a mixed pressure is formed in the valve chamber and supplied to a mixed pressure port. An armature is affixed to a valve body of the valve device movable in an axial direction, the valve body being connected to a suspension device, wherein the armature is displaceable in the axial direction using a solenoid. The electropneumatic converter also includes a damping element configured to dampen the axial movement of the armature and the valve device affixed thereto. The damping element includes at least one of an elastomer or a foamed material. |
