Abstract

533,895. Rotary diaphragm compressors. BLACKMAN, Ltd., KEITH, and KEITH, G. Dec. 13, 1939, No. 32097. [Class 8 (i)] A compressor comprises flexible diaphragms 13 carried by a rotor comprising end walls 1, 2 respectively carrying a hub 6 carried by a ported boss 7 and a trunnion 4 carried by a bearing 5. The boss and trunnion are integral with the end plates of the outer casing 30, and the boss carries an eccentric shaft 10 surrounded by a sleeve 12 carrying U members 11 attached to the diaphragms. The trunnion 4 is turned by a handle. The sleeve and hub receive lubricant through passages 28, 28a. Air is supplied and discharged through radial ducts 19 leading to passages in the boss. The sleeve 12 may be omitted. The outer plates 15 of the compressor chambers may also be omitted, the chambers then being closed by contact with the casing 30.
