Metering valve for the metered delivery of color pigments particularly in apparatuses for mixing coloring substances.

摘要

The present invention relates to a metering valve (1) for the metered delivery of color pigments particularly in apparatuses for mixing coloring substances. The valve (1) comprises a color pigment feed duct (2) which defines a delivery port (3) controlled by a laminar shutter (10) which can move transversely with respect to the port (3) itself. The port (3) is arranged in a plane which is inclined with respect to a vertical plane and has, on the plane of contact with the laminar shutter (10), a configuration which tapers in the direction of translation of the laminar shutter (10) toward the end of the port (3) which is last-closed by the laminar shutter (10).
