Turbo-machine for compressing a gaseous or liquid fluid

摘要

The turbomachine has a tubular housing (1) which is centered on an axis. A rotor (2) is generally centered on the axis (10) in the housing and bearings (3,4) supporting the rotor in the housing for rotation about the axis. The rotor is formed by a small-diameter shaft (5) extending along and centered on the axis, formed with mounting collar, and carried by the bearings. The annular disks are fitted axially together and formed with radially outwardly extending vanes. One of the disks are fitted with and secured to the mounting collar.
