High pressure fuel container for high pressure fuel injection system of diesel engine of motor vehicle, has protection unit formed from material having mechanical resistance greater than resistance of material of common rail case

摘要

The container has a protection unit (9) with a flange forming part. A channel (92) connects fuel passage channels (15, 19) and an inner passage channel (7a) of a common rail case (7, 8). The protection unit is formed from a material having mechanical resistance greater than resistance of material of the rail case. An intersection part is provided on a curved surface of the flange forming part. METALLURGY- The protection unit is made up of the material such as SCM steel i.e. steel with chromium or molybdenum, steel for bearings or steel formed by carburization processes.
