A centrifugal clutch, in particular a centrifugal powder clutch, comprising a housing and a rotor mounted for rotation in said housing. The rotor has at least one circumferential groove, each wall of which is provided with a passage that is at an angle different from 90 DEG to the median plane of the rotor, thereby to promote circulation of the powder when the clutch slips. |
