ABSTRACT:
An inflator for tires having a housing adapted to be hand held, with air compressor means including an electric motor mounted in the housing for supplying air under pressure to a tire. Adjustable valve means is mounted on the housing and operatively connected to the compressor means for selecting a predetermined air pressure for deliver to the tire, the valve means movable between open and closed positions. A hose is operatively connected to the valve means to provide air under pressure for delivery to the tire from the compressor means in the open position of the valve means, and switch means is mounted in the housing and coupled to the motor for supplying electrical energy to the motor in the energized position of the switch means. Actuating means is operatively associated with the valve means and the switch means, the actuating means releasing the switch means from its energized position when the closed position of the valve means is obtained when a predetermined pressure is reached in the valve means, such that the supply of compressed air to the tire ceases.
