Abstract: A fuel injection device (IA) includes: a needle valve; and a nozzle body (10) that accommodates the needle valve (20), which reciprocates along the axis (AX) of the nozzle body, and that includes a fuel passage having a fuel inlet port formed in a portion of the inner wall surface (13) of the nozzle body that comes in contact with the needle valve (20). The nozzle body (10) has a first fuel passage (14) and a second fuel passage (16). A merged injection hole (18), at which outlet ports of the first and second fuel passages (14, 16) merge, is formed in a surface of the nozzle body (10). The passage cross sectional area of the merged injection hole (18) is larger than the sum of the passage cross sectional areas of the first and second fuel passages (14, 16). The axis line (Ll) of the first fuel passage (14) and the axis line (L2) of the second fuel passage (16) intersect each other in the merged injection hole (18).

Abstract: The fuel injection valve for a motor vehicle fuel injection engine has a small diameter piston (54) lifted hydraulically by a piezo-electric actuator (51) via larger diameter piston, to lift the valve needle (1). The small diameter piston has a body (54a) and a variator ring (54b) to vary the area under pressure. The variator ring cooperates with a stop to vary the surface of the piston exposed to the pressure.

Abstract: The fuel injector for a motor vehicle internal combustion engine has a needle (1) to open a fuel spray orifice (11). The valve has a control chamber (2) with a high pressure fuel passage to produce a closure force on the needle. A control valve (3) has a valve chamber (31) and a low pressure opening (33) opening into a low pressure passage (104). An actuator (51) has a piston (52) to position the needle.
