AIR-COOLED POWER MECHANISM Russian patent published in 2001 - IPC

FIELD: mechanical engineering; engines, pumps and compressors. SUBSTANCE: cylinder of each above-indicated machine needs cooling. If engine is used as power unit of gases cutters or mechanical saws, air cooling should be employed as water cooling cannot be practically provided. Holes or channels for cooling air are provided in rotating and stationary disks, thanks to which cooling of engine cylinder is effected. Flanges made on external surface of cylinder improved its cooling additionally. In other design versions, connectors between rotating disk and output shaft are made of shape to operate as fan blades and provide required air flow. EFFECT: improved reliability, provision of long service life. 5 cl, 5 dwg
