In order to reduce the friction of a dry-running solenoid valve (1) with a valve housing (2), in which an electric coil (3) and a magnet armature (5) are arranged, and with a valve element (8) which can be actuated by the magnet armature (5) in an axial actuating direction for opening and closing the solenoid valve (1), in which the coil (3) generates a magnetic flux which, when the solenoid valve (1) is actuated, flows via a magnetically conductive valve housing outer wall (2c) of the valve housing (2) to the magnet armature (5), it is provided according to the invention that a magnetically conductive flux element (12) be provided in the valve housing (2) and introduce at least 80%, preferably at least 90%, and particularly preferably 100%, of the magnetic flux flowing over the valve housing outer wall (2c) into an armature end face (5B), facing the coil (3), of the magnet armature (5).

A dry-running solenoid valve for injecting a gaseous fuel into a combustion chamber or a prechamber of an internal combustion engine, with a valve housing, in which an electric coil and a magnet armature are arranged, and with a valve element that can be actuated by the magnet armature in an axial actuation direction for opening and closing the solenoid valve, wherein the coil generates a magnetic flux, when the solenoid valve is actuated, which flux flows via a magnetically conductive valve housing outer wall of the valve housing to the magnet armature, wherein the magnet armature has an armature shaft, and the valve element has a valve shaft which is separate from the armature shaft, wherein the magnet armature actuates the valve shaft via the armature shaft when the solenoid valve is actuated, wherein a buffer element made of plastic is arranged between the armature shaft and the valve shaft.
