Claims

[Scope of utility model registration request]

The pressure of the fluid taken into the space limited by the meshing of the pair of scroll members by meshing them with each other and causing them to move in a relative orbit around each other. In a scroll-type fluid machine that discharges fluid by changing the flow rate, the outer edge of the spiral body of one scroll member is attached to the inner surface of the end plate of one scroll member and/or the sliding contact plate mounted thereon. 1. A scroll-type fluid machine characterized by forming a gap that is blocked by the outer circumferential end of the spiral body of the other scroll member when it comes into contact with the outer circumferential surface of the spiral body of the other scroll member.
