Abstract

The present invention relates to a fluid machine. A pump integrated expander (A) includes a pump unit () and an expansion unit (). In the pump unit (), a casing member () supports a gear pump (), a rotating shaft () and a driven crank mechanism (). In the expansion unit (), a casing including a main body () and a casing member () supports an expander () including a fixed scroll () and an orbiting scroll (). The pump integrated expander (A) is divided into the pump unit () and the expansion unit () by separating at the fitted portion of a tubular portion () on the pump unit () side and a smaller inner diameter portion () on the expansion unit () side and by pulling the eccentric bush () out of a drive bearing ().
