Title: Universal toroidal circuit for hydraulic torque converters

Abstract: The improved design of a closed toroidal circuit enabling various arrangements of bladed converter members or elements, with many of them standardized for the economical manufacture of various types of converters. The shapes of the outer and inner walls of the toroidal circuit in a radial converter plane are determined by a construction trapezoid and construction rectangle, respectively, that are specified by a system of rectangular coordinates and which have their corners rounded by arcs of specified radii. The outer and inner walls are tangent to an infinite number of circles the diameter of each of which is formulated in relation to the distance of the circle center from the converter axis and the maximum radius of the circuit.
