Abstract: A scroll fluid machine includes a revolving scroll in which a revolving wrap stands upright on an end plate supported revolvably on a drive shaft, and a fixed scroll which is provided opposite the revolving scroll and in which a fixed wrap stands upright on an end plate. The revolving and fixed wraps overlap to form a compression chamber for compressing a fluid by causing the revolving scroll to revolve. The scroll fluid machine further includes a rod-shaped member attached to the end plate of the revolving scroll and extending to a rear surface side of the fixed scroll, which is a side not opposing the revolving scroll. A revolving plate is attached to the rod-shaped member, provided with a pin crank mechanism, and supported revolvably on the drive shaft. The revolving plate is provided with a sealing unit that seals the compression chamber in an axial direction.

Abstract: A scroll expander includes a driving scroll body having a first axis line a driven scroll body having a second axis line shifted with respect to the first axis line, a bearing plate including two plates coupled to the driven scroll body and having the second axis line a cylindrical driving pin attached to the driving scroll body, and a cylindrical guide ring attached to the bearing plate and having an inner diameter larger than an outer diameter of the driving pin. The driving pin includes an outer circumferential surface in contact with an inner circumferential surface of the guide ring. A hard film including diamond-like carbon is formed on the outer circumferential surface of the driving pin. The inner circumferential surface of the guide ring includes a polymer resin material with self-lubricity.

Abstract: A scroll expander includes: a driving scroll body having a first axis line as a rotary shaft line; a driven scroll body having, as a rotary shaft, a second axis line shifted with respect to the first axis line; a bearing plate having the second axis line as a rotary shaft; a cylindrical driving pin attached to the driving scroll body; and a cylindrical guide ring attached to the bearing plate and having an inner diameter larger than an outer diameter of the driving pin. Four driving pins are disposed on the circumference of a circle around the first axis line at an equal interval. Four guide rings are disposed on the circumference of a circle around the second axis line at the equal interval so as to correspond to the four driving pins.
