With therise of the water in the steam boiler, the float valve ismoved upwardly, so that the middle group of ports isgradually closed, and the pressure in the dischargepipe of the feed pump gradually increased and themotion of the feed pump retarded. The steam cylinderof the feed pump is provided with a pressure regulator.
