    摘要: The invention relates to a metering device for introducing liquid reducing agent into an exhaust gas pipe. The metering device has a working tank with contents, a delivery unit which is connected to the working tank and the delivery direction of which can be reversed, and a metering valve which is connected to the delivery unit. The metering valve is supplied with contents by the delivery unit and is designed to dispense the tank contents in a discharge direction. The metering valve is designed and connected to the delivery unit in such a way that the delivery unit establishes a negative pressure between the delivery unit and the metering valve when the delivery direction is reversed. The negative pressure causes gas to be drawn off through the metering valve against the discharge direction. The invention also relates to a method for operating a metering device for introducing liquid reducing agent into an exhaust gas tract. The method has the steps of providing a delivery unit that is connected to a metering valve and to a working tank, and discharging liquid reducing agent via a metering valve in a discharge direction. The method further has the step of emptying the metering valve by drawing gas into an emptying flow direction, which is the opposite direction from the discharge direction, achieved by operating the delivery unit in the opposite direction to that of the delivery direction.

    摘要: A metering device for introducing liquid reducing agent into an exhaust gas pipe. A metering valve is supplied with contents from a working tank by a delivery unit and dispenses the tank contents in a discharge direction. The delivery unit establishes a negative pressure between the delivery unit and the metering valve when the delivery direction is reversed. The negative pressure causes gas to be drawn off through the metering valve against the discharge direction. The delivery direction is reversed by either a feed pump with a reversible effective direction or a feed pump and a repolarization valve which communicates with the feed pump and transposes an inlet and an outlet of the feed pump.
