INJECTOR

FIELD: hydraulic devices for dispersing and supply of liquid for windscreen of transport facilities; various industries where such device are required. SUBSTANCE: injector is provided with chamber having hole for delivery of liquid and flat nozzle where flow of liquid is compressed and accelerated over entire length of nozzle; this flow escape through nozzle exit section forming flat jet at required opening angle since horizontal walls of nozzle converge towards nozzle exit at definite angle and vertical walls are bent by quadratic curve forming segments of this curve in plan cut off by chords passing through points of intersection of nozzle exit of preset width with curve at angle to its axis (large for ellipse) which is equal to half difference between two right angles and preset jet opening angle; ratio of nozzle exit section to sectional area of nozzle inlet is no more than 1:5. EFFECT: enhanced efficiency due to increased rate of fan-shaped flow with no increase of pressure of washing liquid and its consumption. 4 dwg
