Abstract

566,019. Centrifugal pumps. GILKES & GORDON, Ltd., G., and FLEMING, N. June 1, 1943, No. 8782. [Class 110 (i)] A main pump 3, 6 is primed by a small pump 14 mounted in a liquid tank 2 and delivering to an injector 26 drawing air from 3, 6 by a pipe 29 and returning the liquid to the tank. The inlet ports 18 of pump 14 are controlled by valve 19 held in open position by a spring 20 and moved up to close 18 by pressure liquid from the main pump delivery through a pipe 23 to the chamber below the valve. The valve has a small port 22 through which normally passes cooling-water to the pump 14 and ejector, and thence by pipe 13, 12 to the gland of the pump shaft.
