Oilless air compressor driven by universal motor

摘要

An improved oilless air compressor (32) which is driven by a high speed universal motor (33). A sprocket (49) and belt driven pulley (66) are arranged to reduce the compressor speed. A motor driven fan (48) and baffles (120,123,124,129,131,133) are provided to direct cooling air in predetermined sequences over the motor and compressor components to increase the operating life of the compressor components, to optimize the compressor efficiency and to reduce the temperature of the compressed air output. The compressor is provided with improved intake and exhaust valves (96,97) and restrictor surfaces (108,117) which limit movement of the valves. IMAGE
