US Patent 7520813 Torque limiter having two mechanical inlets

A torque limiter is provided with a first plate that rotates a second plate via a plurality of balls. The second plate shares the same axis as the first plate. Each ball is suitable for escaping from a respective housing in order to cease driving the second plate when the torque exceeds a predetermined threshold. Each housing includes a first orifice and a second orifice facing each other and formed respectively in the first plate and in the second plate. The torque limiter is remarkable in that it includes first and second distinct inlets for causing the first plate to turn about its axis.
