Title:
VARIABLE VELOCITY FLUID COUPLING
Document Type and Number:
Japanese Patent JPS563327
Kind Code:
A
Abstract:
PURPOSE:To enable a high stabilization of a rotative speed at a load side, by a method wherein a plurarity of continuous slits are provided in the radial direction of a core ring. CONSTITUTION:By the aid of slits made continuously in a radial direction in a core ring 7, a free surface current of a working fluid, cycling in a path, flows out stably from the slits 8 without being shut off by an inner circumference ring 7b and an outer circumference ring 7c, whereby the current is not dispersed in 2 directions. As a result, a rapid change in pressure does not occur, and a current of the working fluid, cycling in a circuit of impellers 3 and of runners 5, is improved. Thus, an unsteady velocity range, which occurs partially at an output shaft, i.e., a load side, can be removed, and simultaneously, an efficiency is improved, whereby a rotative speed is highly stabilized.
