Abstract

The present disclosure relates to a nozzle (23, 24) for a rear suction assembly (20) for a road cleaning vehicle (10). The nozzle (23, 24) comprises a nozzle housing (40) forming a nozzle chamber (41) extending and converging between a nozzle inlet (42) and a nozzle outlet (43). At least one guide wall (65, 66, 67, 68, 69) mounted in the nozzle chamber (41) forming a plurality of passageways (70, 71, 72, 73, 74, 75) for dividing air flowing through the nozzle chamber (41) between the nozzle inlet and outlet (42, 43).
