Abstract

Активный рассекатель для форсунки, содержащей полый цилиндрический корпус с внешней резьбой для подсоединения к штуцеру распределительного трубопровода для подвода жидкости, и, закрепленную в нижней части корпуса, накидную гайку с рассекателем потока жидкости, причем в корпусе, соосно ему, выполнено цилиндрическое отверстие, в верхней части которого установлен сетчатый фильтр, а в нижней части установлена дроссельная шайба с жиклером и рассекателем, отличающийся тем, что рассекатель потока жидкости прикреплен к торцевой поверхности накидной гайки и выполнен стержневого типа в виде усеченного тетраэдра, закрепленного к торцевой поверхности накидной гайки, ребрами которого являются стержни с закрепленными на них лопастями с упорами таким образом, чтобы была возможность их вращения от потоков, исходящих из дроссельной шайбы с жиклером форсунки, при этом ребра основания тетраэдра также соединены стержнями с закрепленными на них лопастями и упорами, при этом проекция оси дроссельной шайбы с жиклером на основание тетраэдра совпадает с точкой пересечения его биссектрис, а к торцевой поверхности дроссельной шайбы, соосно и осесимметрично жиклеру присоединен диффузор, при этом диаметр меньшего основания усеченного конуса диффузора равен диаметру жиклера, при этом диаметр большего основания усеченного конуса диффузора равен диаметру окружности, вписанной в горизонтальную проекцию основания тетраэдра, центром которой является точка пересечения его биссектрис.An active divider for an injector containing a hollow cylindrical body with an external thread for connecting to the nozzle of the distribution pipe for supplying fluid, and, secured in the lower part of the housing, a union nut with a fluid flow divider, and a cylindrical hole is made in the housing, coaxially to it, in the upper part of which a strainer is installed, and at the bottom there is a throttle washer with a nozzle and a divider, characterized in that the liquid flow divider is attached to the end surface flare nut and is made of the rod type in the form of a truncated tetrahedron fixed to the end surface of the flare nut, the ribs of which are rods with blades fixed to them with stops in such a way that they can be rotated from the flows coming from the throttle washer with the nozzle nozzle, while the ribs of the base of the tetrahedron are also connected by rods with blades and stops fixed to them, while the projection of the axis of the throttle washer with the nozzle on the base of the tetrahedron coincides with the intersection point of its bisectors, A diffuser is connected to the end surface of the throttle washer, coaxially and axisymmetrically to the nozzle, while the diameter of the smaller base of the truncated cone of the diffuser is equal to the diameter of the nozzle, while the diameter of the larger base of the truncated cone of the diffuser is equal to the diameter of the circle inscribed in the horizontal projection of the base of the tetrahedron, the center of which is its intersection point bisectors.
