摘要：To provide a scroll-type expander having a relatively simple structure, small energy loss, and high durability and reliability. A pump-integrated expander 27 includes an expansion unit 50 configured as a scroll-type expander. In the expansion unit 50, a working fluid passage 51e extending from a suction port 51c open to the outside to an inlet 51d open to an expansion chamber 54 is formed in a base 51a of a fixed scroll 51. A working fluid supplied from the outside is guided to the expansion chamber 54 by the working fluid passage 51e. In order to receive a thrust force acting on an orbiting scroll 53 and to prevent the rotation of the orbiting scroll 53, a ball-coupling anti-rotation mechanism 56 using balls as rolling members is disposed between a stepped face 52c of an expander housing 52 and a base 53a of the orbiting scroll 53.
