Sleeve 5 slides along axis A-A on shaft 6 and is connected by turning pair B to cam-levers 3 which have lugs d engaging annular recess b of clutch body 1. Cam-levers 3 are connected by turning pairs D to pressure plate 2. Owing to the action of spring 4, the working surface of cam-levers 3 tends to clamp friction disk a between the clutch body and pressure plate 2. Body 1 is keyed to shaft 7, and sleeve 8 of friction disk a can slide along a feather key of shaft 6. To release the clutch, sleeve 5 is shifted to the right against the tension of spring 4.
