Abstract
A system for cooling a turbo compressor includes two compressing parts on opposite ends of a rotational shaft driven by a motor. Fluid from a fluid chamber within the casing of the device is supplied to a bearing chamber when the temperature of the bearing chamber increases. A supply passage is formed in a first support where the radial bearing for supporting a load in the axial direction is formed. The open-and-shut valve supplies fluid when the temperature of the bearing chamber increases.
