Disclosed is a portable air compressor accessory connectable to the chuck-end of a hand held electric drill via a shaft mount capable of rotating in the same axis of rotation as the chuck. The shaft passes through a housing via bearing mounts. Within the housing is a plurality of radially oriented piston-containing cylinders connected at their respective check valve governed air discharge outlets to a manifold. The manifold discharges to a suitable outlet connection to provide compressed air. Each cylinder has a check valve governed air inlet. Within the housing, the shaft attaches to a cam having a spindle, offset from the axis of rotation, swivel connected to a hub. Piston rods are connected at one end to hub and at the other end swivel connected to the respective pistons. One rod is fixedly connected to the hub, the other rods are swivel connected to the hub as articulating rods. |
