摘要： A gas metering valve for an internal combustion engine. The gas metering valve includes a housing in which a gas chamber is formed, which includes an inlet opening and an outlet opening. A movable valve element is situated in the gas chamber, which is movable by an electrical actuator against the force of a return spring and which cooperates with a valve seat for opening and closing the inlet opening. A blocking valve is situated between the valve element and the outlet opening, which opens in the flow direction to the outlet opening and blocks in the opposite flow direction.

摘要： A method for detecting correct connection of at least one energy reservoir to a vehicle electrical system of a motor vehicle. The method includes: ascertaining a voltage dropping at the energy reservoir, and/or a current flowing through the energy reservoir, and/or a voltage present at a terminal as a representative of the electrical system voltage, when the electrical system voltage exceeds or falls below at least one desired voltage, preferably as a function of at least one magnitude characteristic of the energy reservoir, such as an open-circuit voltage or gassing voltage; comparing the ascertained magnitude, such as the voltage and/or current, with at least one limit value; correct connection of the energy reservoir to the vehicle electrical system, or at least one fault, is inferred as a function of the comparison.
