Abstract
At least one spraying device (1) and several supply lines (8) for supplying the spraying device with a coating product, the lines being linked to a connecting assembly (3). Each downstream end (6) of a line is provided with a gate valve which can be controlled by an actuator (30) which is itself controlled and which is positioned at the entrance to a product supply pipe (2) for the spray device (1). The actuator (30) and the connecting assembly (3) can be displaced in relation to each other (F1-F4) in such a way that the actuator (30) can be positioned selectively facing a downstream end (6) of one of the supply lines (8) and can manoeuvre the valve of the line. The ends (6) of the lines are arranged in rows and columns and an assembly (30) composed of the actuator and connected to the supply pipe (2) is mobile parallel to a plane surface (5a) where these line ends (6) open out.
