ABSTRACT:
A suction type road sweeping vehicle generally has a self propelled chassis with road wheels. Mounted on the chassis is an air tight container for collecting dust etc. swept up by the vehicle. Dust etc. is sucked up into the container via pick up conduits and nozzles, the suction being provided by a fan. When hydraulically driven brushes and the like are used the hydraulic oil must be cooled. This is effected by introducing water into the conduits to mix with the cooling stream of air flowing into the container, separating the cooled water from the air and debris and utilizing the cooled water to cool the hydraulic oil.
