DEVICE TO GENERATE SERIES OF MOVING FLUID DROPS

FIELD: measurement technology.SUBSTANCE: invention relates to investigation of properties of liquids, namely to batchers with external control for repeated measurement and dispensing a preset volume of liquids and can be used in scientific researches in the areas of hydrodynamics, chemistry, biology, medicine etc. Device to generate series of moving fluid drops comprises a body in the form of a rectangular parallelepiped, ribs of which are made of interconnected angle bars. Inside the body there is a frame in the form of a rectangular parallelepiped, ribs of which are made of interconnected racks with guide rollers installed on them. Inside the frame there is a vertically fixed rectangular box with open top and bottom ends. On opposite sides of the box along the axis of the frame movement there are n identically made through holes arranged vertically in a row to accommodate hollow needles with their ends pressed with a holder fixed inside the frame on the corresponding side of the box. Opposite the needles spikes on the frame the first plate is fixed. Inside the body, on the outer side of the frame, opposite the first plate there is the second plate with guide rollers installed on it. One side of the second plate is equipped with a handle. On the other side of the second plate there is a rod fixed with the possibility of back-and-forth movement in a hole of the third plate vertically mounted inside the body. Bulge on the end of the rod is directed towards the first plate. Between the second and third plates there are springs.EFFECT: technical result is generation of identical size series moving at a fixed distance from each other fluid drops.1 cl, 2 dwg Изобретение относится к области исследования свойств жидкостей, а именно к дозаторам с внешним управлением для повторяющегося отмеривания и выдачи заданных объемов жидкостей и может быть использовано при проведении научных исследований в области гидродинамики, химии, биологии, медицины и др. Устройство для генерации последовательно движущихся капель жидкости содержит остов в виде прямоугольного параллелепипеда, ребра которого выполнены из соединенных между собой уголков. Внутри остова размещен каркас в виде прямоугольного параллелепипеда, ребра которого выполнены из соединенных между собой реек с установленными на них направляющими роликами. Внутри каркаса вертикально закреплен прямоугольный короб с открытыми верхним и нижним торцами. На противоположных сторонах короба вдоль оси перемещения каркаса идентичн
