Abstract

The self-propelled road-sweeper has a rotary transverse brush (3) in a housing (8) connected by ducts (10) to the bin (7) and water is sprayed into the ducts to aid in compacting the dust. The water is distributed from a tank (6) located beneath the bin and valves with filters (20) are provided to allow the water to drain back into the tank for recycling. The valves automatically close when low pressures exist in the bin, and reopen as the pressure rises. The valve seats may be formed by holes (14) in the floor of the bin (7) and the balls (15) may be located by cages (16) in chambers (17) with lateral outlet pipes (19) to the tank (6).
