Actuating unit for a piezo-electrically controlled fuel injection valve

Tubular hollow body for a piezo actuator module and method for production thereof

Fuel injector, has coupler body whose rigidity is determined such that gap between coupler body and single-row trained biasing spring is increased by locally diameter enlargement of coupler body

Fuel-injection valve for air-compressing, auto-igniting internal combustion engines comprises a valve with a corrugated washer partly surrounding the periphery of a bolt section of a valve bolt

Fuel injector with improved guided stroke movement of the valve closing part

An automotive fuel injection valve has concentric spring with elastic side-extensions subjected to lateral shift

Fuel injection valve, especially for diesel engine, has pin element aperture for ball element, spring element acting on pin element towards initial position in which connection between valve chamber, low pressure region is closed

Fuel injection valve for self-igniting internal combustion engines comprises a valve with a spring sleeve partially enclosing a bolt section of a valve bolt

Valve e.g. for injection device of internal combustion engine sleeve end of spring sleeve, which rests on contact surface of valve member, which is protruding radially outwards
