Abstract

103,669. Maag, M., and Aeppli, A. Jan. 24, 1916, [Convention date]. Void. [Published under Sect. 91 of the Act]. Movable-abutment type; compensating for irregularity of flow: discharge and suction passages.-To avoid eddy losses and obviate pulsations, the teeth of a rotary pump of the type having intermeshing gear-wheels 2, 3 are made of helical form, and the inlet conduit 8 and the outlet conduit 9 are provided laterally of the wheels, as shown. The teeth are made more or less pointed at the ends, as shown in dotted lines in Fig. 2; and the angle a of advance of the teeth, the width b of the wheel, and the pitch t are so rotated that tan a = b/t. Double-helical wheels may be employed.
