Document Type and Number:
WIPO Patent Application WO/2016/016958
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a scroll-type fluid machine which reduces the load on a rotation prevention mechanism and which can improve performance and service life. This scroll-type fluid machine is characterized by being provided with a fixed scroll, an orbiting scroll which is provided opposite of the fixed scroll and which turns, a casing which is provided on the outside of the orbiting scroll, a driveshaft which turns the orbiting scroll, a back plate which is provided separated from the orbiting scroll and connected to the drive shaft, and multiple rotation prevention mechanisms which are disposed between the back plate and the casing, wherein a gap is provided between the portion of the back plate where the drive shaft is connected and the portion where the rotation prevention mechanisms are disposed, and the back plate and the orbiting scroll are brought into contact without connecting in the radial direction.
