Fuel metering unit for the fuel injection system of a combustion engine

High-pressure fuel pump comprising a ball valve in the low-pressure inlet

Overflow valve for e.g. high pressure pump of storage injection system, has vent holes that are formed in main portion for venting spring chamber, and are configured to connect spring chamber directly to channel in housing

Check valve, especially for a high pressure pump of a fuel injection device for an internal combustion engine

High-pressure fuel pump for fuel injection system of internal combustion engine, has spring collar whose surface is pressurized with closing pressure, by which valves are closed, before fuel is pressurized with high-pressure by piston

Check valve for a high-pressure pump of a fuel injection system for an internal combustion engine

High-pressure fuel pump with a ball valve in the low-pressure inlet

Fuel injection device for use as common rail injection system for self-ignition combustion engine, has fuel injector injecting fuel into combustion chamber, where ventilation of device into fuel tank takes place in low-pressure region
