Abstract
A power generation apparatus according to the present invention includes: an expander; a generator that includes a generator rotor driven by the expander and a stator disposed outside the generator rotor in the radial direction; and a casing that includes an expander chamber accommodating the expander and a generator chamber accommodating the generator. The casing includes a first communication portion that causes an expansion chamber which gradually expands a working medium by the expander in the expander chamber to communicate with a front generator portion which is located nearer the expansion chamber than the generator in the generator chamber and a second communication portion that causes a portion which is a downstream portion from the expansion chamber and is located near the expansion chamber with respect to the generator to communicate with the front generator portion.
