Document Type and Number:
Japanese Patent JP2016050509
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an air compressor capable of enhancing cooling performance of a compression mechanism part.SOLUTION: In a crankcase, an internal fan 41 being blade elements is disposed on a non-compression mechanism part side of a flywheel 40. Each blade 41b of the internal fan 41 is positioned on or extended to a further peripheral side than bearings 36a, 36b of a compression mechanism part 7. A pair of vent holes 42a are formed to penetrate a flat plate part 49 of the flywheel 40 and a flat plate part 41a of the internal fan 41. In addition, a pair of vent holes 42b are formed further inside than the vent holes 42a to penetrate the flat plate part 41a of the internal fan 41, the flat plate part 49 of the flywheel 40, an eccentric collar 37b, a spacer 38b, a spacer 38a and an eccentric collar 37a in the axial direction. Furthermore, a vent hole 43a is formed in a first connecting rod 33a, and a vent hole 43b is formed in a second connecting rod 33b.SELECTED DRAWING: Figure 5
