Abstract

Дюзата ще намери приложение в двигателостроенето. С нея се намаляват количеството на въглеводородите в изго-релите газове и шумът от запалването на горивото. Дюзата включва тяло (1), завършващо с глава (3), в която е офор-мено вентилно седло (6) и са пробити разпръскващи отвори (4). В тялото (1) е поместена игла (5), в горната част на която има (7) към него. Над тялото (1) са разположени две пружини (8 и9), поместени една в друга. Иглата (5) е притисната към вентилното седло (6) от вътрешната пружина (8) чрез пружинната тарелка (7), а външната пружина (9) посредством шайба (10) е притисната към рамо (11), опряно върху тялото (1). Междурамото (11) и петата (19) има хлабина, така че околната повърхнина на масленияцилин-дър, образуван от вътрешния ръб на всеки разпръскващ отвор (4), проектиран върху повърхността на иглата (5) при положение на обрана хлабина между петата (19) и ра-мото (11), е по-малка от напречното сечение на разпръск-ващия отвор(4). 1 претенция, 4 фигуриThe nozzle will find application in engine building. It reduces the amount of hydrocarbons in the burnt gases and the noise from fuel ignition. The nozzle includes a body (1) ending with a head (3) in which a valve seat (6) is formed and spray holes (4) are drilled. A needle (5) is housed in the body (1), at the top of which there is a (7) attached to it. Above the body (1) there are two springs (8 and 9), placed inside each other. The needle (5) is pressed against the valve seat (6) by the inner spring (8) through the spring plate (7), and the outer spring (9) by means of a washer (10) is pressed against an arm (11) resting on the body (1) . There is a clearance between the arm (11) and the heel (19) so that the surrounding surface of the oil cylinder formed by the inner edge of each spray hole (4) projected onto the surface of the needle (5) in the retracted position clearance between the heel (19) ) and the arm (11), is smaller than the cross-section of the spray opening (4). 1 claim, 4 figures
