Definitions
- Conventional fuel injection systems may have leaks caused by construction.
- the injectors may have leaks. Due to the amount of leakage, a temperature-induced shrinkage of the fuel volume in the system can be compensated. When special fuel injection systems occur when starting the engine delays that are undesirable.
- a further preferred exemplary embodiment of the fuel injection system is characterized in that the valve bushing has a through-hole extending in the radial direction, which communicates with the high-pressure through-hole and in which a valve sleeve is arranged, the opening to the low-pressure region and an opening having the high-pressure passage hole. Via the two openings of the valve sleeve, a connection is created between the low-pressure region and the high-pressure region.
- Figure 2 is a schematic sectional view through a check valve device according to a first embodiment
