511 513 the exterior surface 515 defines a maximum radial dimension of the armature assembly 500 the interior surface 517 defines a first portion of a first passage 521 the first portion of the first passage 521 is adapted to permit fuel flow through the first portion 510 of the armature assembly 500 the cross sectional shapes of the exterior surface and interior surfaces 515 517 can be a variety of shapes for example each cross section of the exterior surface 515 and the interior surface 517 can be substantially circular and coaxial with the armature assembly axis 501 such that the exterior and interior surfaces 515 517 define an annular wall 519 the annular wall 519 includes a second passage 531 the second passage 531 is adapted to permit liquid fuel flow therethrough the second passage 531 is in fluid communication with the first passage 521 of the armature 500 and the fuel outlet end portion 150 of the fuel injector 100 by this arrangement the second passage 531 can permit liquid fuel flow from the fuel inlet portion 110 to the fuel outlet portion 150 of the fuel injector 100 the second passage 531 extends along a second passage axis 532 the second passage axis 532 can be disposed at an angle relative to the armature assembly axis 501 of the armature 500 preferably the second passage axis 532 of the second passage 531 is disposed at an angle of about 10 degrees to the armature assembly axis 501 of the armature 500 a cross section of the second passage 531 can be a variety of shapes e g substantially circular a diameter of the second passage 531 can be greater than a fuel bore in a conventional armature according to one example of.
