SPRAYER Russian patent published in 2005 - IPC

FIELD: agricultural engineering.

SUBSTANCE: sprayer has tank for storage of toxic chemicals, suction filter, pump, pressure filter, regulator-distributor, and pressure lines for supplying of working fluid to spraying devices. Pressure lines are provided with gauging inserts. Additional gauging inserts are positioned in front of each working device. Sections of gauging inserts are determined from formula: f_n=K_n·f_l cm², where f_n is section of n-line; K_n is coefficient determined by calculation depending on length of line and local resistances, K=(0.6-0.9); f_l is section of line.

EFFECT: increased efficiency by leveling pressure of working fluid in all pressure lines.
