A nozzle assembly (3) for a fuel injection valve (1) and a fuel injection valve (1) for a combustion engine with the nozzle assembly (3) are disclosed. The nozzle assembly (3) comprises a valve body (7) with a central longitudinal axis (15), the valve body...

To improve the injection fuel mass accuracy of a fuel injector, it is necessary to make the fuel injector perform seat valve (114B) opening and closing operation quickly. When the shapes of a fixed core (107) and an anchor (102) are optimized to improve th...

The valve (113) has a magnetic coil (103) arranged in a radial direction on an outer side of a sleeve (105), and a magnetic core (111) arranged in a radial direction in an inner side of the sleeve. An armature (106) is arranged axially opposite to the core...

Allocation of fuel to be injected into the engine takes place at the cylinder surface shell established by the radius of the valve closing body (4) and the height of a torsion chamber (37). The resulting cylinder surface shell is smaller than the cross-sec...

An electromagnetic fuel injector (1) for an internal combustion engine, comprising a main body (4) having a central cylindrical cavity (5) adapted to act as a duct for the fuel, a valve (6) which is disposed to close an end of the central cylindrical cavit...

Allocation of fuel to be injected into the engine takes place at the cylinder surface shell established by the radius of the valve closing body (4) and the height of a torsion chamber (37). The resulting cylinder surface shell is smaller than the cross-sec...

Electromagnetic actuator (4) for a fuel injector (1); the electromagnetic actuator (4) is provided with an electromagnet (11), which has a fixed magnetic core (17) which is delimited at the base by a first annular contact surface (18), and with an anchor (...

An engine fuel injector (10) includes an internal fuel passage (12) in which pressure waves can develop upon opening and closing of an injection valve (22). A fuel pressure damper (48) is associated with the fuel passage (12) and operates to vary the inter...

The fuel injection valve comprises a valve-closing body forming a seal with a valve seat surface formed on a valve seat body, and a twisting module. The twisting module comprises several wires (42) twisted around one another and inserted in a sleeve (44) ....
