Abstract
109,421. Weir, G. & J., and Weir, J. G. May 23, 1917. Regulating or controlling.-A centrifugal pump p is controlled by means involving the pressuredifference at two points in the divergent discharge nozzle a. Venturi pipes f, g lead from the nozzle a to the ends of a cylinder d, the piston n of which is normally balanced by the pressure in the pipe g and that in the pipe f supplemented by a spring s. In the form shown, the piston n is connected to a valve h which controls the supply of fluid to a turbine t. In a modification, the piston-rod is linked to the controlling-rheostat of an electric motor. Specification 24073/13 is referred to.
