Abstract
The air compressor of the present invention includes an air storage tank with a hollow cylinder having a closed lower end mounted in the upper wall of the tank, so as to project within the interior of the tank. A drive motor mounted on the tank has a piston rod connected thereto and extending downwardly into the hollow cylinder, to reciprocate therein and pump air into the tank. The piston rod has an enlarged head slidably mounted within the cylinder, and an aperture formed through the piston rod head with an operable valve, to permit air flow into the cylinder, but prevent air flow out of the cylinder through the piston rod head aperture. An intake port with an operable valve is formed in the closed lower end of a hollow cylinder, to permit air flow into the tank but prevent air flow out of the tank. An exhaust port formed in the tank may be connected to a hose or other items as desired, to provide compressed air.
