Abstract
An electromagnetic valve, in particular for a motor vehicle air spring system, has a valve closing body which, in its basic position, shuts off a valve outlet and, for this purpose, is pressed against a valve seat by a restoring spring. To assist the opening process, a valve spring is also provided. The valve spring is supported at one side on a valve seat body and at the other side on a spring pot, which is arranged on the valve closing body. Preferably, a tubular section of the spring pot bears, non-displaceably in a lateral direction, directly against the valve closing body. An elastic sealing element may either be arranged on the end side of the valve closing body, or held laterally by a section, which forms an enclosure, of the spring pot.
