<p>The invention relates to a solenoid valve, more particularly, for tank ventilation in motor vehicles, comprising at least one valve opening forming a sealed seat (103) and a valve member (20) for opening and closing the at least one sealed seat (103) and cooperating with the latter, said valve member being spring-loaded by electromagnets against the restoring force of a readjusting spring (30). The invention is characterized in that a flow element (70) throttling the flow of a gas is mounted downstream from the valve member (20), the configuration of said flow element matching the cross section of the opening of the sealed seat (103) that cooperates with the valve member (20) for determining (dosing) the flow rate of the gas through the cross-sectional area of the flow element (70) when the solenoid valve is open in such a way that the surface of the cross section of the opening of the effective valve seat is 2.5 times bigger, preferably more than 9 times bigger, than the surface of the effective cross-sectional area of the flow element (70).</p> |
