Description

Требовани , предъ вл емые к сальнику форсуночной иглы, заключаютс  в том, чтобы не дать возможности воздуху, давлением пор дка 70 атмосфер, просачиватьс  из форсунки наружу, не вызыва  в то-же врем  значительного трени  иглы, ведущего к нежелательному заеданию последней в сал нике .The requirements imposed on the injector needle gland are to prevent air, a pressure of about 70 atmospheres, from the nozzle seeping out without causing at the same time a significant friction of the needle leading to undesirable jamming of the latter in the valve. .

Набивание сальника требует большой тщательности, а в дальнейшем наблюдени  и осторожного подт гивани .Stuffing the gland requires great care, and further observation and careful tightening.

Предлагаемое приспособление дл  уплотнени  иглы форсунки в двигател х Дизел  и имеет целью или устранить сальник форсунки совсем, или же I облегчить выполнимость требований, предъ вл емых к нему, при чем в основе того и другого лежит известный принцип применени  смазочных веществ, нагнетаемых под давлением в окружающую уплотн емое тело полость.The proposed tool for compacting the nozzle needle in a Diesel engine is designed to either eliminate the nozzle seal completely, or I to facilitate the fulfillment of the requirements imposed on it, and this is based on the well-known principle of applying lubricants injected under pressure the cavity surrounding the body.

На чертеже фиг. 1 изображает форсунку без сальника дл  иглы в продольном разрезе, фиг. 2 - продольный разрез приспособлени , нагнетающего уплотн ющее смазрчное вещество.In FIG. 1 shows a nozzle without a gland for a needle in longitudinal section; FIG. 2 is a longitudinal section of a device that forces a sealing lubricant.

Приспособление дл  уплотнени Compaction device

иглы форсунки в двигател х Дизел  посредством масла, нагнетаемого в окружающую иглу кольцевую выточку 6 направл ющей втулки 1 (фиг. 1), состоит из двух скалок 4 ц 5 (фиг. 2) , разного диаметра, ход щих в корпусе I. С целью повышени  давлени , нагнетаемого смазочного вещества, скалка 4 имеет больший диаметр, чем скалка 5 и находитс  под давлением распыливающего воздуха, поступащего через канал 2 в камеру 3; в последней находитс  слой масла или другой жидкости, служащей дл  уплотнени  скалки 4, от давлени  этого масла, а не воздуха, на ход щегос  над ним.nozzle needles in Diesel engines through oil pumped into the needle surrounding the annular recess 6 of the guide sleeve 1 (Fig. 1) consists of two skalons 4 c 5 (Fig. 2) of different diameters that run in housing I. increasing the pressure of the injected lubricant, the rolling pin 4 has a larger diameter than the rolling pin 5 and is under the pressure of the atomizing air entering through the channel 2 into the chamber 3; in the latter there is a layer of oil or other liquid, which serves to seal the rolling pin 4, against the pressure of this oil, and not of the air flowing over it.

Таким образом,скалка 4, притерта  на плотность масла в 100 атмосфер , под давлением наход щегос  над ним распыливающего воздуха, перемещаетс  вниз и, упира сь в скалку 5,- вызывает перемещение и этой последней. Скалка 5, перемеща сь вниз, производит давление на уплотн ющее вещество в камере б, при чем благодар  меньшему диаметру скалки 5, удельное давление в камере 6 должно получитьс  выше, чем в камере 3. Под этим давлением уплотн юща Жидкость,Thus, the rolling pin 4, ground on the oil density of 100 atmospheres, under the pressure of the atomizing air above it, moves downward and, resting against the rolling pin 5, causes the latter to move. Rolling pin 5, moving downwards, produces pressure on the sealing substance in chamber 6, and due to the smaller diameter of the rolling pin 5, the specific pressure in chamber 6 should be higher than in chamber 3. Under this pressure, sealing liquid,
