Compressor having a piston performing simultaneous functions

Abstract

AN COMPRESSOR HAVING A PISTON PERFORMING SIMULTANEOUS FUNCTIONS, which consists of a piston with a top part having a diameter smaller than that of the bottom part. Over the piston, in a reservoir (which has an outlet for compressed air) over the piston cylinder, is located a valve that covers the whole of the top opening of the cylinder. The bottom reservoir, where a crankshaft is located, is connected to the top part of the piston cylinder through passages that allow air to flow from this bottom chamber into the top part of the cylinder. The bottom reservoir has intake valves that open as the piston moves up and close as the piston moves down.
