Abstract

11,879. Berliner-Maschinenbau Akt.- Ges., [formerly L. Scheartzkopff]. June 6. [Patent of Addition to No. 13,167, A.D. 1907.] Centrifugal pumps.-Relates to improvements i n the end-thrust balancing - device for centrifugal pumps described in Specification N o . 13,167, A.D. 1907. The impeller d and balancing-piston a are secured to a shaft w and are capable of slight endwise movement. A balancing- chamber f is formed in the casing e. Fluid leaks from the pump delivery space to the chamber f around the periphery of the piston a and escapes through an annular throttling space formed by shoulders c<1>, c<2> on the piston and casing respectively. The variation of this throttling space by the axial movements of the shaft causes a variation of the balancing pressure in the chamber f. The end-thrust is accordingly automatically balanced.
