Abstract: A circuit for dispensing fluids, in particular, dyes, inks, paints and the like, including pump means including a variable-volume chamber with at least one flexible wall. The pump means communicate with an output duct for dispensing the fluids. Two one-way valves are mounted in series in the outlet duct.

Abstract: A device for campling a container in a mixer for fluids comprises a clamping unit (7) selectively operable for clamping a container by the application of compressive forces. Resilient compression members (40) and a sensor (50) are associated with the clamping unit for detecting the application of a predetermined clamping force to the container by means of the determination of the deflection of the resilient compression members (40) proportional to said predetermined clamping force.

Abstract: A dispensing machine for the metered delivery of fluid products, especially painting products. The dispensing machine includes a dispensing head with a nozzle, and the ends of a plurality of delivery ducts communicate with the dispensing head in order to feed a plurality of fluid products thereinto. A mixing device, in particular a rotating turbine, is mounted between the ends of the delivery ducts and the dispensing nozzle to continuously mix the fluid products coming from the different delivery ducts and simultaneously entering the dispensing head.

Abstract: A system for the preservation, transportation and dispensing of dyes provides for a combination of a hollow reservoir having at least one deformable wall so that its internal volume can vary from a maximum to a minimum substantially close to zero, and an opening for the connection of the reservoir to a dye-dispensing circuit; the reservoir is airtight so that its internal volume corresponds to the volume of dye contained therein in essentially any condition of use.
