Gas injector having reduced wear and damping device

A gas injector for injecting a gaseous fuel, comprising:

• a solenoid actuator including an armature, an internal pole, and a coil;
• a closure element which opens and closes a gas path on a valve seat, wherein the armature is connected to the closure element;
• a closed lubricant chamber filled with a lubricant and in which the armature is arranged, wherein the lubricant ensures the armature is lubricated;
• a flexible sealing element which seals the lubricant chamber in relation to the gas path;
• and
• a braking device arranged in the lubricant chamber and configured to brake the closure element during a process of restoring the gas injector from an open state into a closed state;
• wherein the braking device includes a brake pin, a damping chamber that is filled with lubricant and is in fluid communication with the lubricant chamber, and a resilient brake element, wherein the brake pin and the resilient brake element can be operatively connected to the closure element during the restoring process, and the brake pin is configured, during a process of restoring the gas injector, to displace lubricant out of the damping chamber into the lubricant chamber to damp the restoring of the closure element into the closed state.
