<p>The auxiliary control comprises an auxiliary valve providing a valved fuel passage in series fluid communication with a transfer pump outlet, inlet metering passage and pumping chamber downstream of the transfer pump outlet and upstream of the pumping chamber. The auxiliary valve has a valve bore, a valve piston axially shiftable in the valve bore, a spring biasing the valve piston in one axial direction to a first axial position, and a pressure device biases the valve piston in the opposite axial direction with a bias which increases with the regulated outlet pressure.</p> |
