ABSTRACT:
A fluid flow displacement rotary machine is provided which includes a casing including an inclined rib on an inner surface thereof, and a shaft provided coaxially with the casing such that the shaft and the casing are rotatable with respect to each other. A disk is mounted to the shaft and includes a recess that is engageable with the rib to divide the space and such that the disk rotates about the axis thereof when the shaft moves with respect to the casing. The recess only engages with the rib at first and second rib contacting portions. The first rib contacting portion is provided at an intersection of the first end face of the disk and the first side surface of the recess, and the second rib contacting portion is provided at an intersection of the second end face of the disk and the second side surface of the recess.
