ABSTRACT:
A speed governor for a rotational drive includes a rotor arranged to be driven by the rotational drive and located within a housing having a cylindrical inner side wall and an end wall. Centrifugal brake shoes are pivotally mounted on the rotor and contact the cylindrical side wall and the end wall during rotation of the rotor in a first direction and to move and remain out of contact with the cylindrical inner side wall and end wall during rotation of the rotor in the opposite direction. The brake shoes may be moved and retained out of contact with the end wall by riding up over a portion of the rotor.
