The compressor art, namely, such machinery or devices as used to compress gases, is old and differing structural designs are known, many of which are patented.
This invention is concerned with a type of air compressor incorporating a globoid-worm having a plurality of threads in meshing relation with at least one toothed pinion, as exemplified by U.S. Pat. No. 3,945,778, Mar. 23, 1976, and U.S. Pat. No. 3,804,564, Apr. 16, 1954, both granted to Bernard Zimmern. More specifically, the subject invention represents an improvement in such Zimmern compressors insofar as manufacturing costs are reduced, efficiency is improved, and reliability is increased, all as will become evident from the detailed description of the invention set forth hereinafter.
