<p>The invention concerns a module (1) generally parallelepiped in shape, comprising parts (7) wherein emerge at least two bores (8) converging towards a central channel (8) and perpendicular to the end surfaces (2, 3) of the module, and which emerge likewise in said channel (9). Each bore (8) acts as housing for a gate valve (10) whereof the disc (10) is designed, depending on its position, in isolating or in communicating with the central channel, a chamber wherein emerge two channels respectively supplying paint and transporting paint back to the reservoir (17). Each paint supplying or recuperating channel is connected to an outer conduit (17) via a connection (21) comprising a first externally threaded part (20) designed to be urged to be screwed into a conduit (17) and a second part (18) with larger diameter, enclosed by a joint (19) designed to be urged to be tightly interlocked in a well (16) provided in the module (1), in the bottom of which emerges a paint supplying or recuperating channel (12, 13). The part (20) with small diameter of the connection is bent.</p> |
