Abstract
The throttle valve, for a fluid flow and especially a dispersion of solids, has a fluid feed to the passage surface which imposes a rotary flow component in relation to the main flow direction line and around it. Also claimed is a feed system operation, where the fluid flow is given a rotary component round the main flow line, for a throttling cross-section with a rotary symmetrical shape.
