GAS INJECTOR WITH DAMPING DEVICE, ESPECIALLY FOR SHORT STROKES

A gas injector for injecting a gaseous fuel. The gas injector includes a magnetic actuator having an armature, an inner pole, and a coil, a closing element which opens and closes off a gas path at a sealing seat, the armature being operatively connected to the closing element, a sealed lubricant chamber filled with a lubricant and in which the armature is arranged, wherein the lubricant ensures lubrication of the armature, and a brake device which is arranged in the lubricant chamber and is designed to brake the closing element when the gas injector is reset from the open state to the closed state. The brake device has a brake pin, a damping chamber filled with lubricant and fluidically connected to the lubricant chamber via a first fluid path, a resilient brake element, an armature pin which is operatively connected to the armature and includes a guide disk.
