Abstract
A ball actuator comprises a case supporting a striker with an energy storage spring , a control rod movable in translation in a direction parallel to a geometric axis , detent balls and control balls . When the rod is moved in translation by an electromagnetic relay , the control balls escape and enable the detent balls to be freed so that the striker is released. Each control ball is in contact with two detent balls and with the rod so that the forces applied to the rod by the control balls are much lower than the forces exerted by the striker on the detent balls . A high-efficiency actuator is thus achieved requiring a low operating energy and with small overall dimensions.
