<p>An electrical actuator for actuating a valve or other device includes an electrical motor rotating a rotary member and centrifugal body. The centrifugal body is mounted to the rotary member and is biased to normally assume an inner position with respect to the rotary axis of the rotary member, and to move to an outer position by centrifugal force when the rotary member rotates. An actuator pin is normally biased to a non-actuating position but is movable to an actuating position, to actuate a valve or other device, when the centrifugal body is moved to its outer position by centrifugal force upon the rotation of the rotary member by the electric motor.</p> |
