Claim 7:
8. A fuel delivery assembly comprising:
a common rail comprising a reservoir for containing pressurized fuel and including a plurality of outlets for delivery of pressurized fuel from the reservoir to a plurality of fuel injectors, said common rail supported in a fixed position relative to a cylinder head of an internal combustion engine;
a plurality of fuel injector assemblies of claim 1, said valve body having a forward end axially between the nozzle end and the radially projecting shoulder, said forward end supported on the cylinder head with the nozzle end projecting through the cylinder head into a combustion chamber partially defined by the cylinder head; and
a load ring arranged between each outlet and the load receiving surface of each fuel injector assembly, said load ring comprising:
an annular body having a first surface facing either the outlet of the common rail or the load-receiving surface of each fuel injector assembly,
an plurality of resilient arms connected to the annular body, each resilient arm including a connection projecting radially from the annular body and a resilient portion extending from the connection to a free end, each said resilient arm extending along the circumference of the annular body, the free end of each resilient arm including an end portion having a contact surface facing axially opposite the first surface of the annular body, the contact surface of each resilient arm being axially offset from the first surface of the annular body,
wherein said load ring is compressed between the outlet and the load-receiving surface of the fuel injector assembly to bias the forward end of each fuel injector assembly toward the cylinder head, the load ring generating a bias force that is symmetrical with a longitudinal axis of the fuel injector assembly.
