A centrifugal compressor for which theta-alpha > 0 DEG and 0 DEG < theta < 34 DEG, when the angle formed by a diffuser inlet hub-side line (5a) and the radial direction at a point B in the meridian plane is theta, and the angle formed by a tangent line (3b) and the radial direction at a point A of an impeller hub-side line (3a) nearest the inlet of the diffuser (5) is alpha. Thus, skewing of the velocity distribution of a gas within the diffuser of the centrifugal compressor is eliminated.

The invention provides an scroll expander to improve both the reliability and performance. Lubricating oil 6 held at a suction pressure is supplied into a counter-lap side end plate rear face 13d of a revolving scroll 13. Communicating passages 30a and 30b to communicate the end plate rear face 13d and the lap bottom 13b of the revolving scroll center portion are formed to the end plate 13a. Thereby, since the lubricating oil 6 is supplied into a suction part, and discharged lubricating and sealing a fixed scroll 12 and the revolving scroll 13 successively following the expansion process, so as to provide the relible scroll expander.
