A sprayer boom (2) on a vehicle serves for, by means of a number of liquid nozzles (8), spraying a carriageway with a liquid fed under pressure to the nozzles from a storage container via a feed pipe (4). The nozzles are divided into sets each with their valve arrangement (13) for selectively shutting off and opening for liquid supply to the respective set. The sprayer boom is suitable for tasks where the same amount of liquid per area unit must be sprayed across the area the vehicle passes irrespective of the speed of the vehicle, in as much as the nozzle sets can be regulated quickly and easily to optimun functioning at a given speed and a corresponding liquid flow. |
