Claims (5)

1. Уплотняющее устройство между двумя полостями при разных давлениях, которое содержит кольцеобразное уплотнение (52) между двумя концентрическими поверхностями (22, 58), отделяющими упомянутые полости (39, 13), отличающееся тем, что уплотнение (52) сжимается между двумя буртиками (53,54), образованными на упомянутых поверхностях (22,58), в направлении, параллельном их оси, с тем чтобы уплотнить обе упомянутые поверхности (22, 58) и буртики (53, 54).1. A sealing device between two cavities at different pressures, which contains an annular seal (52) between two concentric surfaces (22, 58) separating these cavities (39, 13), characterized in that the seal (52) is compressed between two flanges ( 53.54) formed on said surfaces (22.58) in a direction parallel to their axis in order to seal both said surfaces (22, 58) and flanges (53, 54). 2. Устройство по п. 1, отличающееся тем, что оно используется для топливной форсунки (11) двигателя внутреннего сгорания, содержащей полый корпус (12), несущий сопло и дозирующий клапан (24) для открытия сопла, при этом дозирующий клапан (24) имеет корпус (26), заключенный внутри цилиндрического посадочного места (21) полого корпуса (12), буртики (53, 54) образованы на поверхности (22) цилиндрического посадочного места (21) на наружной поверхности (58) части (59) упомянутого корпуса (26) клапана. 2. The device according to claim 1, characterized in that it is used for a fuel injector (11) of an internal combustion engine comprising a hollow body (12), a nozzle and a metering valve (24) for opening the nozzle, while the metering valve (24) has a housing (26) enclosed inside a cylindrical seat (21) of the hollow body (12), flanges (53, 54) are formed on the surface (22) of the cylindrical seat (21) on the outer surface (58) of the part (59) of the said housing (26) valve. 3. Устройство по п. 2, отличающееся тем, что посадочное место (52) имеет, по существу, круглое сечение; корпус (26) клапана подсоединен к полому корпусу (12) посредством имеющей резьбовую нарезку гайки (31), которая ввинчивается по резьбовой нарезке (19) полого корпуса (12), с тем чтобы деформировать упомянутое сечение для уплотнения как поверхности (22) цилиндрического посадочного места (21), так и наружной поверхности (58). 3. The device according to claim 2, characterized in that the seat (52) has a substantially circular cross-section; the valve body (26) is connected to the hollow body (12) by means of a threaded nut (31), which is screwed onto the threaded thread (19) of the hollow body (12) so as to deform the said section for sealing as a surface (22) of the cylindrical seat places (21) and the outer surface (58). 4. Устройство по п.3, отличающееся тем, что корпус (26) клапана имеет фланец (29), на который действует круглая гайка (31); при этом фланец (29) удерживается у дополнительного буртика (23) полого корпуса (12), торцевой части (62) корпуса (26) клапана придана форма, слегка сходная с усеченным конусом для содействия введению корпуса (26) клапана в цилиндрическое посадочное место (21). 4. The device according to claim 3, characterized in that the valve body (26) has a flange (29), on which a round nut (31) acts; the flange (29) is held at the additional shoulder (23) of the hollow body (12), the end part (62) of the valve body (26) is given a shape slightly similar to a truncated cone to facilitate the introduction of the valve body (26) into a cylindrical seat ( 21). 5. Устройство по п. 4, отличающееся тем, что корпус (26) клапана имеет камеру (38) сжатия, которая сообщается с выпускной камерой (32) через выпускной канал (44) и имеет впускной канал (41) для топлива под высоким давлением, чтобы воздействовать на шток (14), управляющий форсункой (11), при этом выпускной канал (44), будучи управляемым электромагнитом, контролируется затвором (48), а входной канал (41) расположен радиально у кольцеобразной полости (39), буртик (54) корпуса (26) клапана расположен между кольцеобразной полостью (39) и упомянутой частью (62), имеющей форму усеченного конуса. 5. The device according to claim 4, characterized in that the valve body (26) has a compression chamber (38) that communicates with the exhaust chamber (32) through the exhaust channel (44) and has an inlet channel (41) for high pressure fuel in order to act on the rod (14) that controls the nozzle (11), while the outlet channel (44), being controlled by an electromagnet, is controlled by a shutter (48), and the input channel (41) is located radially at the annular cavity (39), the flange ( 54) the valve body (26) is located between the annular cavity (39) and the said part (62) having the shape section of the cone.
