摘要： A solenoid valve is described, its armature having a part that is slidingly displaceable on the foundation bolt and is movable between two stops of the foundation bolt against the tension force of a restoring spring. When the armature strikes the valve seat of the solenoid valve, the slidingly displaceable part moves further under the influence of its inertial mass on the foundation bolt in the closing direction against the tension force of the restoring spring, until it strikes the second stop of the foundation bolt. The resulting transfer of momentum to the foundation bolt reduces impact of the armature on the valve seat and causes the armature to more quickly reach a defined rest position in which the solenoid valve is closed.

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 solenoid valve for controlling an injection valve of an internal combustion engine is provided, including an electromagnet, a movable armature, a control valve member moved with the armature and cooperating with a valve seat for opening and closing a fuel discharge channel of a control pressure chamber of the injection valve, and a sliding piece guiding the armature, which is positioned together with the armature and the control valve member in an armature chamber. For reducing the bounce of the armature, the sliding piece subdivides the armature chamber into a pressure relief chamber connected to a fuel low-pressure connection and an hydraulic damping chamber, into which a fuel discharge channel opens. The damping chamber may be pressure-relieved to a pressure relief chamber via at least one connecting channel provided with a throttle, the speed of the control valve member being lowered during the closing of solenoid valve, before impact on valve seat, by a fuel pressure cushion acting upon the control valve member in the damping chamber.
