CONNECTION REGION BETWEEN A HIGH-PRESSURE DUCT AND A HIGH-PRESSURE CHAMBER, AND FUEL INJECTION COMPONENT HAVING A CONNECTION REGION

摘要

The invention relates to a connection region (10) between a high-pressure duct (12) and a high-pressure chamber (11), a transition region (15) being formed between the high-pressure duct (12) and the high-pressure chamber (11), and the transition region (15) having a first cross-sectional area (13) in the opening region to the high-pressure duct (12) and a second cross-sectional area (16) in the opening region to the high-pressure chamber (11), and at least one intermediate cross-sectional area (23) between the first and the second cross-sectional areas (13, 16). According to the invention, the at least one intermediate cross-sectional area (23) is greater than an imaginary intermediate cross-sectional area that results from a continuous, linear transition between the first and the second cross-sectional areas (13, 16).
