Abstract
A device for supplying at least one sprayer with a liquid coating product comprises at least one valve for controlling the flow of the coating product to the sprayer. The valve comprises a moveable needle, a valve body which defines a circulation volume of the coating product and a seat for supporting the needle in the closed configuration of the valve. A pneumatic driver drives the pointer in translation along an axis away from or towards the seat. The pneumatic driver comprises a piston constrained to move in translation with the needle and mounted slidably in a guide body. The pneumatic driver also comprises an end-piece penetrating into a transfer chamber. The communication line links the end-piece or the transfer chamber with a variable-volume chamber defined by the guide body and a first face of the piston.
