ABSTRACT:
A recirculating paint apparatus comprising a main body provided with a plurality of radially extending openings in communication with a main axially extending delivery channel, and a plurality of selectively operable valve assemblies for controlling communication between different color paints and the delivery channel is disclosed. Each paint is recirculated through its associated valve assembly right up to its valve for controlling flow through an orifice in communication with the common delivery channel so that all areas are subject to recirculating flow and any settling out of pigments or solids in the paint is prevented or minimized.
