Abstract
A device for supplying at least one sprayer with a liquid coating product comprises a plurality of valves for controlling the flow of the coating product to the sprayer, these valves being aligned along a principal axis of the supply device. Each valve comprises a moving needle, a valve body, pneumatic driver for moving the needle in translation, the driver comprising a piston constrained to move in translation with the needle and slidably mounted in a guide body. The principal axis and the separation/approach axis of a valve coincide at a unique point and together define a principal plane of the valve. The separation/approach axis of each valve is contained within a cone centered on an axis perpendicular to the principal axis and belonging to the principal plane of the valve, the apex of the cone being coincident with the unique point.
