Abstract
A solenoid valve for controlling fluids includes: a closing element, which opens and closes at least one outlet opening on a valve seat; a magnetic circuit having an armature, an internal pole and a magnetic return path; and a coil. The armature is connected to the closing element. The magnetic circuit includes (i) a nonmagnetic separating element for interrupting the magnetic circuit and (ii) a magnetic choke device closing the magnetic circuit on the nonmagnetic separating element, which magnetic choke device is a separate individual component which is fixed using a form-locking and/or a force-locking connection.
