Abstract

157,365. Kaplan, V. Aug. 10, 1914, [Convention date]. Casings; impeller blades.-Passages in which kinetic energy of a fluid is converted into pressure energy comprise side walls of considerable divergence, a deflector wall CDG and an opposite wall E. The angle # between the two parts CD and DG should be large and may be a right-angle. The radius r at D must not be greater than the radius R of the opposite wall, and may be considerably less. The length of the passage measured along the line of flow XY is sometimes not greater than the greatest width between the divergent side walls. Applications of such passages as the diffusers of centrifugal pumps, suction tubes and the cells of pump and turbine rotors are described. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the following subject-matter which does not appear in the Specification as accepted. One or more intermediate guiding surfaces may be introduced between the deflector wall and the wall E, and the curvature of these surfaces at the bend should be intermediate R and r. If there be more than one, the curvatures should decrease towards the deflector.
