<p>The present invention relates to an automatic air injection nozzle for an automobile. The present invention provides an automatic air injection nozzle which comprises an air pressure control unit wherein, when an automobile moves and a tire touches the ground, leading to a transformation of the tire, a piston is operated, and the internal air is compressed and supplied into the tire; when the piston returns to the original position, the atmospheric pressure inside is made low, and the external air is taken into the inside; and, when the internal air pressure becomes the determined air pressure or higher, the compressed internal air is not supplied to the tire but is discharged to the outside. The automatic air injection nozzle according to the present invention can continuously maintain a uniform air pressure of the automobile tire by a simple transformation to remove the conventional air injection nozzle mounted on an automobile′s wheel and install the automatic air injection nozzle of the present invention in the pertinent position.</p> |
