IMPROVED WATER RING ROTARY AIR COMPRESSOR ABSTRACT OF THE DISCLOSURE An improved water ring rotary air compressor in which the rotor assembly has a cylindrical bore while the port head includes a cylindrical port sleeve, made from a high lubricity thermoplastic material, which fits within the bore. The use of a high lubricity thermoplastic port sleeve eliminates the need for shimming the port head following an overhaul of the compressor. The port sleeve includes a plurality of longitudinal slots which eliminate cavitation during start up under pressure. A needle valve built into the manifold allows bypass of a portion of the discharge air into the air inlet. Adjustment of the needle valve permits the maintenance of constant air flow as the compressor becomes worn.
