Abstract

14,668. Elling, A. June 23, 1911, [Convention date]. Casings, centrifugal fan and pump. The spaces on each side of fixed diffuser blades are connected by a passage through the blade or in the wall of the diffuser passage, the opening on the inner side of the blades being near the point thereof. Figs. 5 and 6 show one form of opening d<2>. By this means, loss of pressure due to variation of discharge is eliminated. In a pump with a single diffuser blade, the passage connects the inlet and outlet sides of the blade.
