Air separator for air compressor

Claim 1

A separator for an air compressor to separate aqueous vapor and oil gas from an air stream comprising: a vertically disposed casing having an air intake pipe for receiving air from a compressor and an outlet for discharging the air stream without the aqueous vapor and oil gas; a conically converging member mounted adjacent to but spaced from the end of said pipe within said casing; a vertically disposed cylindrical protective sleeve surrounding said member and mounted within said casing; said air intake pipe extending through said sleeve for directing air to be separated onto said member so that the impingement of air thereon effects separation; a zig-zag shaped tube extending from the bottom of said sleeve for conducting air and separated aqueous vapor and oil gas from said sleeve and effecting further separation; a plate mounted in said casing so that air leaving said zig-zag shaped tube is directed onto said plate to effect further separation, the separated liquid thereafter accumulating in the bottom of said casing; a transparent pipe connected to the interior of said casing and extending outside thereof for indicating the level of liquid in said casing; and a round pipe mounted adjacent said outlet and above the bottom of said casing has an open end so as to direct air leaving said zig-zag shaped tube to said outlet.
