may alternatively be permitted to turn on its ball-bearing.
In operation, the outward thrust of the balls forces the cone towards the right, and works the rack-rod (5) of the pump via a lever (6). At idling speeds, the rackrod spring (7) is the only one reacting on the cone, but as the speed rises. another spring (8) begins to come into action, thus balancing to some extent the square-law of centrifugal force. The extra spring is actually in two parts, separated by a washer (9) to prevent surging.
