<p>A power generation apparatus (1) includes an expander (3) and a power transmission shaft (6) that extracts a rotational driving force generated by the expander to the exterior of a housing (5) of the expander. The housing of the expander contains a driving unit of the expander within a space enclosed by a partition wall of the housing. The power transmission shaft includes a magnetic coupling, for transmitting the rotational driving force from the expander to the exterior of the housing, that is divided between the interior and exterior of the housing of the expander through the partition wall. The rotational driving force extracted via the magnetic coupling is used as auxiliary power that supplements the power of a driving source provided separately from the expander when driving a rotating machine using the power of the driving source. A clutch mechanism (18) and a speed variator (17) are provided in a power transmission path that transmits the rotational driving force extracted by the power transmission shaft to the driving source.</p> |
