High pressure applying device for air-compressing auto-ignition internal combustion engine, has high pressure channel comprising blind hole, where section hole in region of hole base opens out into blind hole over sectional surface

摘要

The device has a body (7), in which a high pressure channel (13) is formed for conveying fuel, where the high pressure channel comprises a blind hole (8) and a section hole (9). The blind hole in a region of a hole base (18) is cut by the section hole, where cross section of the section hole in the region of the hole base is smaller than cross section of the blind hole. The section hole in the region of the hole base opens out into the blind hole over a sectional surface (19), which is formed in conical shape.
