When thebucket is at its highest position the valve will be at its extreme point to the right, closing thefirst two ports and leaving the third one open to a passage under the valve from the interiorof the governor to the atmosphere. The valve is caused to move over the ports by the risingand falling of the bucket through the intervention of a bell-crank lever. The operation is asfollows: The space between the bucket and outer case must first be filled with water by thewater running in from the system of heating-pipes; the valve, however, that admits thesteam to the steam-chest must first be closed until this space is once filled, for the conditionof the apparatus is such that when there is no water in this space the bucket will be necessari-ly in its lowest position, and consequently the two ports for admitting steam to the pumpwill be wide open, and the pump will at once commen
