Fluid mixing device, particularly for industrial inks or paints

摘要

An automatic fluid mixing device (1) wherein a cylindrical supporting structure (9) supports a first number of valves (24) angularly spaced along a first circumference (C1), and a second number of valves (24) angularly spaced along a second circumference (C2) concentric with and inside the first (C1); the valves (24) are three-way types, and present a control rod (33) extending axially from one end; and the mixing device (1) presents a blade type selecting device (96) movable angularly about an axis (19) through the center of the circumferences (C1, C2), and which singly engages an end portion (101) of the control rod (33) to move the rod (33) axially and so open the valve (24).
