FLUSHER TRUCK Russian patent published in 2016 - IPC E01H3/02 

FIELD: transport.

SUBSTANCE: invention relates to machines for motor roads summer maintenance. Flusher truck comprises basic vehicle with tank and main nozzles. On main nozzles inner surface curvilinear guides are arranged, which curvature has helical line positive rotation direction. Machine also contains additional nozzles, communicated with tank through water pump with high-pressure pulsator, on inner surface of which curvilinear guides are arranged, which curvature has helical line negative rotation direction. Additional nozzles are installed above main ones and connected with air fan pressure chamber by means of ejector, which ejecting input is communicated with pipeline and tank. Fan is equipped with suction branch pipe with air filter, containing housing with conical bottom and condensate drain, and top cover, inside of which perforated metal cylinder is arranged, connected with suction branch pipe, cleaned atmospheric air input union in form of narrowing nozzle and equipped with removable metal mesh, deflecting partition, made porous on nozzle side and solid on perforated metal cylinder side. Water pump blades are made with outer surface coating from nano-sized glass-like film of tantalum oxide.

EFFECT: technical result consists in reduction of corrosion and cavitation effects on water pump blades, which enables reducing of power consumption.
