A high-pressure fuel pump (10), which is used in particular for direct-injection internal combustion engines, comprises a housing (12) which has a low-pressure inlet (20) and a high-pressure outlet (22). In the housing (12) there is a pump chamber (34) whi...

A mechanism for controlling forces in a valve assembly such as flow induced forces. The valve assembly comprises a valve body defining first and second flow passages. A valve is movable in the valve body along an axis to control fluid flow between the firs...

The fuel injector, for an internal combustion motor, has a restricted passage (50) with at least one throttle, which links the control pressure zone (46) of the fuel injection valve (12) with the high pressure fuel pump (10). The throttle has an elastic di...
