Rotary compressors with primary and secondary oil separation means

摘要

An air compressor wherein oil mist lubricates a rotor stator in the compressor casing whereby an oil mist is produced in the compressed air provided with primary and secondary oil removal sections. The primary and secondary oil removal sections are connected by an oil separation manifold. The manifold and the secondary oil removal section are in a housing detachable from the main compressor housing. The main and detachable housings communicate with a tube which has apertures in its side wall at its inlet end which end communicates with the interior of the main housing and apertures in its side wall at its outlet end which end communicates with the manifold.
