Valve for inflation of tires depending on the engine, characterized by comprising a bushing with external thread for coupling in the hollow of the cylinder for the spark plug, whose bushing has an axial bone of double diameter, corresponding the smaller to the threaded head, and the major being provided to receive a shaft with axial hollow that closes the passage to a ball that eventually tends to rest on the step determined by the diameter differences of the inner hollow of the bushing by the action of a spring disposed between the ball and the inner head of the threaded rod.
