Abstract
A liquid paint suction rod including an upstream tube, a flexible intermediate tube and a rigid downstream tube, which includes a downstream elbow, the downstream tube delimiting a series of passage sections defining centers constituting a trajectory, the downstream elbow extending along a curved part of the trajectory, along which the passage sections are substantially discoid and have a preferably constant diameter; in order to avoid imposing too great a curve on the intermediate tube while offering a reduced head loss for the paint passing through the rod and while being easy to manufacture, the curved part is in the shape of a planar arc of circle, having a curve radius, the ratio of the diameter to the curve radius being less than 1.
