Abstract
A fluid machine includes a thrust bearing support supporting a dynamic thrust bearing that includes a first dynamic thrust bearing and a second dynamic thrust bearing and including a first bearing base and a second bearing base fixed to each other via a spacer member. The fluid machine includes a main passage through which fluid flows from a motor chamber toward an operation chamber, and a space between an inner side of the spacer member and an outer side of the first dynamic thrust bearing and the second dynamic thrust bearing in a radial direction of a rotary shaft. The space communicates with a first through hole of the first bearing base communicating with the motor chamber and a second through hole of the second bearing base communicating with the main passage. The thrust bearing support includes a connecting passage interconnecting the space and the main passage.
