Abstract
A solenoid valve, such as, for example, a tank-vent valve f or tank venting in motor vehicles, includes at least one valve orifice forming a sealing seat, and a valve member, which cooperates with the sealing seat for releasing and closing it, the valve member being stressed by at least one spring element and activated by an electromagnet. An essentially unstressed neutral position of at least one additional spring element, which acts upon the valve member in the activation direction, is provided in which the valve member is set apart from the sealing seat. In this manner, the impact of the valve member on the sealing seat, which may be accompanied by distracting noises and wear, is damped.
