Claims (2)

1. Способ работы дизельной форсунки путем подачи топлива через топливоподающий канал в подыгольную полость, дросселирующий канал и цилиндрический зазор между внешней поверхностью запорной иглы и внутренней поверхностью корпуса форсунки, отличающийся тем, что топливо в цилиндрическом зазоре центральной части иглы используют для гидрозапирания и охлаждения форсунки.1. The method of operation of a diesel nozzle by supplying fuel through a fuel supply channel to a needle room, a throttling channel and a cylindrical gap between the outer surface of the locking needle and the inner surface of the nozzle body, characterized in that the fuel in the cylindrical gap of the central part of the needle is used for hydraulic locking and cooling of the nozzle. 2. Устройство для осуществления способа работы дизельной форсунки, содержащее полый корпус с топливоподающим каналом, запорную иглу, размещенную в корпусе коаксиально внутренней поверхности, цилиндрический зазор между внешней поверхностью иглы и внутренней поверхностью корпуса, подыгольную полость, образованную нижней частью запорной иглы с корпусом, дросселирующий канал, соединяющий подыгольную полость с цилиндрическим зазором, а также каналы гидрозапирания и охлаждения форсунки, отличающееся тем, что каналы гидрозапирания и охлаждения форсунки совмещены и выполнены путем расширения цилиндрического зазора в центральной части запорной иглы объемом не менее двух минимальных цикловых подач топлива, а дросселирующий канал, образованный зазором между корпусом и уплотняющим пояском на игле, выполнен длиной не менее половины диаметра запорной иглы.2. A device for implementing a method of operating a diesel nozzle, comprising a hollow body with a fuel supply channel, a locking needle placed in the housing coaxially on the inner surface, a cylindrical gap between the outer surface of the needle and the inner surface of the housing, a needle cavity formed by the lower part of the locking needle with the housing, throttling a channel connecting the needle room cavity with a cylindrical gap, as well as channels for the hydraulic locking and cooling of the nozzle, characterized in that the hydraulic locking and cooling channels eniya nozzles aligned and formed by extending the cylindrical gap in the central part of the closure needle of not less than twice the minimum cyclic fuel feed, and the throttle channel formed by a gap between the housing and the sealing belt on the needle, is made a length not less than half the diameter of the needle stop.
