COMPRESSOR

摘要

According to a compressor of the present invention, a multi-angular contact ball bearing is installed between a crank shaft and a frame, and inside the crank shaft, an oil flow path penetrated toward the ball bearing is formed, and an upper end height of the ball bearing is formed lower than an upper surface height of the frame, thereby smoothly supplying oil sucked in through the crank shaft to the ball bearing. Thus, a friction loss can be significantly reduced in the ball bearing.
