THRUST GAS BEARING, CENTRIFUGAL COMPRESSOR EQUIPPED WITH SAME, AND REFRIGERATION DEVICE EQUIPPED WITH SAME

摘要

A cooling flow path (67) includes a first flow path (61b) and a second flow path (62b). The first flow path (61b) is formed at one axial end side of a first base part (61) and extends from an axis side of the first base part (61) toward an outer circumference side thereof. The second flow path (62b) is formed at the other axial side of a second base part (62) and extends from an outer circumference side of the second base part (62) toward an axis side thereof. The second flow path (62b) is located at a downstream side of the first flow path (61b).
