Abstract
In a device (1) for applying fluids (3), consisting of a carrier pipe (11) provided with outlet openings (13), of a paint distributor (21) rotatably mounted on the carrier pipe (11), and of an applicator roller (7) held on the paint distributor (21). The paint distributor (21) is formed by an insert (22) shaped with multiple corners and assembled from a pipe section (23) and ribs (24) which are shaped onto it, with the applicator roller (7) being in contact with the ribs (24). Furthermore, axially aligned notches (27) are in an inside surface of the pipe section (23) and the notches (27) act in conjunction with an outer surface of the carrier pipe (11) to form throttle ducts (28) which are connected to the inner space (12) of the carrier pipe (11). A cavity (29) is provided as a reservoir between adjacent ribs (24) of the insert (22), the cavities being connected to the throttle ducts (28) by means of bores (30) in the pipe section (23). This structure achieves a constantly satisfactory distribution of paint over long periods of operation and permits the paint distributor (21) to be completely cleaned without difficulty within a short time period. Furthermore, the device (1) posses…
