Abstract (en)

[origin: JPH01206101A] PURPOSE: To make distance fluctuation be compensated by connecting a guide eye to a disk-shaped rotor via fin and forming the fin as a tangential extension on an inlet-side end of one of spiral strips. CONSTITUTION: A guide eye 5 of an eccentric guiding arrangement 26, 27 is connected to a disk-shaped rotor 1 via fin 29 with it longitudinal direction tangentially extending toward a spiral and connected with an inlet-side end of a spiral-shaped strip 3. Consequently, since a high rigid in the tangential direction and a high elasticity in a radial direction can be obtained, a distance fluctuation generated between two working points can be compensated automatically.
