FIELD: armaments. ^ SUBSTANCE: invention relates to combat vehicles equipped with the system designed to clean protective glass of sight-range-finder by fluid-and-air means. In compliance with this invention, drain valve lever is turned through 90, fluid is drained into vessel. Thereafter, the said valve is closed by turning its lever into horizontal position. The system is blown with compressed air by turning aforesaid lever into vertical position. Fluid temperature control pickup effects continuous fluid temperature. The fluid temperature reduced to +5C, microprocessor control unit sends control signal to the valve to remove fluid from the tank. The fluid removed from the vessel, aforesaid pickup sends control signal to microprocessor control unit and, therefrom, to the valve for protective glass to be blown with compressed air in winter. ^ EFFECT: high efficiency of maintenance. ^ 1 dwg |
