Claims (4)

1. Клапанная форсунка для впрыскивания топлива для двигателей внутреннего сгорания, содержащая корпус, подвижный запорный элемент, взаимодействующий с седлом клапана, которое выполнено на образующем это седло элементе и которое переходит в направлении течения потока топлива в выпускное отверстие, отличающаяся тем, что изготовленный из листового металла образующий седло элемент (16) выполнен чашечной формы, полученной путем глубокой вытяжки, и имеет донную часть (19) и кольцевую стенку (20), причем седло (24) выполнено на обращенной к кольцевой стенке (20) верхней поверхности (21) донной части (19).
2. Клапанная форсунка по п. 1, отличающаяся тем, что к противоположной от кольцевой стенки (20) образующего седло элемента (16) нижней поверхности (31) донной части (19) прилегает и приварена к ней распылительная шайба (34) по меньшей мере с одним распылительным отверстием (39) в зоне, перекрываемой выпускным отверстием (25).
3. Клапанная форсунка по п. 1 или 2, отличающаяся тем, что запорный элемент (7) выступает через направляющее отверстие (14) в направляющей шайбе (15), прилегающей к торцу (26) кольцевой стенки (20) образующего седло элемента.
4. Клапанная форсунка по п. 2, отличающаяся тем, что в корпусе (1) установлено опорное кольцо (49), удерживаемое с помощью предусмотренного в корпусе (1) буртика (55) и прилегающее к распылительной шайбе (34) таким образом, что образующий седло элемент (16) своей кольцевой стенкой (20) прижат к уступу (45) в корпусе.
