SCROLL-TYPE FLUID MACHINE

摘要

A scroll-type fluid machine (10) in which an edge load acting on a main bearing is relaxed (reduced) to extend the life of the main bearing. A small-diameter shaft section (14a) formed on the one end side of a rotating shaft (14) is supported by a sub-bearing (16), and a large-diameter shaft section (14b) formed on the other end side of the rotating shaft (14) is supported by the main bearing (15). A rotatable annular ring (32) is provided between the large-diameter shaft section (14b) and the main bearing (15).
